Boost Your Fertility by Combating Estrogen Excess the Bane of All Infertility

Estrogen (estradiol) is the hormone that is responsible for majority of the cases of infertility in both male and female. Estrogen dominance relative to progesterone and or testosterone is the major hormonal imbalance in infertility treatment. Every other symptoms or manifestation of infertility stems from hormonal imbalance. This is exactly what most fertility doctors and reproductive endocrinologists ignore to master. You must realign these hormones in proper balance to boost fertility. For infertile women, estrogen must be balanced with progesterone while infertile men must balance estrogen with testesterone.

Both men and women consume environmental toxins in their food and drink which are loaded with estrogens. In addition, women make a lot of endogenous estrogens while men above 40 aromatize testosterone back to estrogen and dehydro-testesterone. Estrogen excess causes several known female infertility issues like fibroid tumors, uterine polyps, endometriosis, adenomyosis, endometrial hyperplasia, anovulation, primary ovarian failure, ovarian cysts (polycystic ovary disease), luteal phase defect, and tubal blockage. On the other hand, the male infertility factors like poor sperm profile is caused by lack of testesterone (stimulate sperm production) relative to dorminant estrogen (from aromatization of testosterone) which suppress male potency.

Unlike testesterone, estrogen is a group of three hormones: estriol (good estrogen), estrone (bad estrogen), and estradiol (the real bad and ugly estrogen). By the way hormones are chemical messengers that power cellular function. They are produced by endocrine or ductless glands that secret these chemicals directly into the blood stream. Hormones like estrogen and progesterone are secreted by some glands but exert their effect in other organs that has surface proteins called receptors. The receptors are like lock while the hormones behave like keys. Therefore, estrogen has its receptors in reproductive organs like ovary, uterus, birth canal, breast, and falopian tubes. Other estrogen receptors include the fat cells, liver, brain, and thyroid gland.

Estrogen can come from diet or is made from within the body (endogenous estrogens). Exogenous estrogens come from food sources like soy which has isoflavons and genistein which are forms of plant estrogen called phytoestrogen. Flax, carrot, red rasberry, black cohosh, and squash are all forms of estrogens. Other sources of estrogen are meat and dairy loaded with bovine growth hormones. Zenoestrogens are names given to estrogens from petroleum products (organophosphates), pesticides, dioxins, insecticides, herbicides, and synthetic fertilizers (especially by eating genetically modified foods).

Another source of estrogen is myco-estrogens which comes from the colon through the activity of candida. Yeast come from bread, nuts, seeds and packaged foods. Yeast crave sugars and multiply in seconds to produce estrogens called mycoestrogens. And because yeast is saprophytes, they coexist with bad bacteria (anaerobes) in the colon. The bad bacteria include bacteriodes, clostridium and E.coli. These bad bacteria produce an enzyme called glucuronidase which makes it hard to eliminate used estrogen from the liver. Therefore, they raise estrogen level indirectly.

Having related all these, to boost fertility and combat infertility, estrogen dominance must be controlled for the infertility to turn to conception. Estrogen elimination must take a multi-pronged approach at five cardinal places:

Liver Detoxification: 
Aggressive cleansing detoxification of sluggish liver is necessary. The Chinese believe that it is the liver that controls ovulation. Yes, if you don't make the eggs, you are not going to make the babies. You detoxify the liver with liver friendly fruits and vegetables. The chief of which is green leafy vegetables and bitters. The list include watercress, dandelion greens, cucumbers, lemon juice, lecithin, B-complex vitamins, milk thistle, broccoli, cabbage, cauliflower and NAC (N-acetyl cysteine).

Colon Cleansing: 
Do a special type of colon cleanse with saline laxative like Epsom salt, olive oil and lemon juice. Added to that are anti-yeast herbs like caprylic acid, oil of oregano, and pau d'arco. More vital is to eliminate beta glucuronidase enzymes that prevents phase II liver detoxification and elimination of estrogen with calcium d-glucarate. D-glucarate breaks down glucuronidase produced by the bad bacteria in the colon. They preserve glucuronic acid which is necessary for conjugation and elimination of spent estrogen in the liver. Otherwise estrogen is reabsorbed into the circulation where it goes back and causes further harm.

Aromatization Blocker (Aromatase Inhibitors): 
Aromatization is a process of turning one hormone into another. Testesterone is responsible for both male and female libido. It is also necessary to stimulate sperm production in males. Therefore, aromatase inhibitor will prevent testesterone from turning into harmful estrogen. An aromatase inhibitor is also necessary in blocking testesterone from turning into dehydrotestesterone which is the hormone responsible for hair loss in both male and females. Dehydrotestesterone (and estrogen) are also responsible for prostate cancer in males. By the way, prostate is the male equivalent to the uterus. MYOMIN is the ultimate aromatase inhibitor. Myomin is a blend of four Chinese herbs developed by Dr. Chi who was a researcher with the Park Davis Drug Company. Myomin is also anti-inflammatory and can stimulate interleukin 6 (IL6) and tumor necrosis factor that can shrink fibroids and ovarian cysts. Combating inflammation is central to any disease management. Myomin can also blocks estrogen receptors.

Estrogen Receptor Blockers: 
You must block estrogen at the receptor sites. Without receptors, estrogens will no have any effect at the target organs. Receptors are surface proteins that modulate the internal activities of estrogens to minimize their damaging effects. Myomin is a non-selective estrogen receptor blocker. It is better than tamoxifen which is a selective estrogen receptor blocker and only works in the breast and not the reproductive organs and fat cells. By the way fat cells manufacture estrogens themselves and myomin can block this process also.

Dissolve the Tumor or Fibrosis: 
This is necessary because the causes of infertility is due to women fibrosis diseases which hamper chances of fertility. Tumors or cyst anywhere in the body is unacceptable. Excess estrogen is free radical generating, inflammatory, fibrosis-forming and carcinogenic. Myomin is also great here because it can balance hormones especially with DIIM (diindolemethane). However, the infertile surfferer need a blend fibrinolytic enzymes. Fribrin is a type of protein that cause problem and mount immune response that cause most infertility problems.

These include uterine fibroids, endometriosis, ovarian cysts, polyps and cancers. Vitalzym is the enzyme of choice. It contains a blend of proteolytic or protein eating enzymes that dissolve all these tumors regards of where they are in the body. These enzymes also clean the blood, modulate the hormones, clean out bacteria and viruses and regulate the blood PH. Myomin and DIIM can stop series of miscarriages which is a form of inflammatory response and fetus rejection. Obstetricians in Europe use myomin to stop miscarriages (regarded as a type of infertility if it occurs three or more times).

In a nutshell, to combat infertility and boost fertility due to estrogen excess, you must clean the liver and colon by aggressive detoxification, add calcium d-glucarate to the mix. You must further block estrogen at the receptor sites, use aromatase inhibitors like MYOMIN and DIIM. To cap it up, use a systemic proteolytic enzyme blend like Vitalzym to eat up any tumor or growth that is already generated by excess estrogens. Yes, hormonal balance is necessary for the man to remain potent and for the woman to conceive a baby. These five outlined mechanisms enhance the harmonious dance of steroids (sex hormones) that sets the stage for fertility and potency. Any treatment that can boost fertility can cure infertility.

Reasons for Pregnancy Failures

It is the dream of every woman to become the mother. Motherhood is the immortal part of the woman’s life. Woman once get married, want to start the family. It is like a dream come true for a woman when she becomes pregnant.

Pregnancy is a fulfilling experience for every woman.

Every woman wants to enjoy the experience the pregnancy and wants to be the mother. Instead of emphasizing the stresses and strains of motherhood and divisions among mothers, the findings reveal that--regardless of background or life circumstances--mothers across the globe have a great deal in common and derive deep satisfaction from motherhood.

But according to the latest survey, around 2 million of the women are childless due to the problems in the pregnancy.

Here, I am mentioning you the reasons for pregnancy failures along with there solutions. I feel every woman should read it and should enjoy the experience of motherhood. I feel that if I am able to solve even the problem of one woman then I will be the happiest person in this world.

1. Infertility in Women
Infertility in the women is found to be the main cause in getting the women pregnant. In spite of the successful intercourse and the transfer of the sperm to the women ovule and even the ovulation takes place but the chromosomes from the women are not indulged in the ovule and as a result the egg fails to develop in the embryo and the pregnancy is found to be failed in such women. Sometimes infertility in the women is found from the birth. But, very rare cases of infertility from the birth were noted.

Pelvic inflammatory disease is found to be one of the major causes of the infertility in women. Pelvic inflammatory disease comprises a variety of infections caused by different bacteria that affect the reproductive organs, appendix, and parts of the intestine that lie in the pelvic area. About 25% of the women who develop pelvic inflammatory disease are found to suffer from the infertility. Pelvic inflammatory disease significantly increases the risk of ectopic pregnancy (fertilization in the fallopian tubes). This infection particularly damages the fallopian tubes and leads to the infertility in the women.

Endometriosis is found to be another cause of infertility in women. Endometriosis is the condition in which the tissue that normally lines the uterus (endometrium) grows on other areas of the body causing pain and irregular bleeding. This damages the egg’s passage. Thus, the transfer of the egg to the fallopian tube is prevented and the pregnancy doesn’t occur.

2. Ovulation Problems
Ovulation problem is found to be the major and most prominent problem in getting pregnant. About 41% of the women face the problem of ovulation in their life span either temporarily or permanently. Ovulation problem is explained as—the ovaries don’t release an egg each month. Ovulation problems result when one part of the system that controls reproductive function malfunctions. This system includes the hypothalamus (an area of the brain), pituitary gland, adrenal glands, thyroid gland, and genital organs. Ovulation is often the problem in women who have irregular periods or no periods.

In the ovulation the sperm is transferred from the man to the woman but the fertilization of the egg fails. Polycystic ovarian syndrome is a common cause of anovulation and infertility in women. There are several possible ways to attempt ovulation induction in women with polycystic ovaries. Clomid tablets are found to be the best and easiest method to treat the ovulation problems in the women. Clomid is used by women want to become pregnant or having problem in becoming pregnant. Clomid works by causing ovulation to occur.

3. Hormone Imbalance
Hormonal imbalance causes the pregnancy problems in about 8% women around the globe. Progesterone is the main hormone that is responsible making the problems in the women pregnancy. Progesterone is necessary for the formation of the egg in the female ovum. If the less amount of the progesterone is present in the women body then the formation of the egg fails and as a result women are not able to become pregnant. Progesterone is the female hormone that causes the lining of the uterus to thicken in preparation for a potential fetus. Ovulation may not occur because the hypothalamus does not secrete gonadotropin-releasing hormone, which stimulates the pituitary gland to produce the hormones that trigger ovulation. Thus, you need to consult your doctor to check the progesterone levels in your body, and if are found lower than the standard levels. Then, please ask doctor to prescribe some medicines that will increase the levels of progesterone and help you in becoming pregnant.

4. Poor Nutrition
Poor nutrition is the cause of many diseases and thus is also related to the pregnancy failures in the women. Proper nutrition is very essential for the women to get pregnant. Lack of nutrition disturbs the formation of egg and thus failure in the pregnancy in noted among the women who are having poor nutrition. Hence to avoid the pregnancy problems, women should take the balanced diet. Women can even contact the dietician for the proper diet to remain fit and fine to get pregnant.

5. Physical Problems
Painful intercourse in one of the physical problem that leads to the failure in the pregnancy, perhaps due to something physically wrong. It can also be that she is afraid and unable to relax. Thus, these women avoid the intercourse and don’t get pregnant. Physical damages like accidents, sports like weight lifting, cycling may damage the fallopian tube. As a result these women fail in getting pregnant. Sexually transmitted diseases also damage the ovulation by the infection as a result these women fail to carry a child.

6. Sexual Dysfunction 
Sexual dysfunction in the women is the problem that arises due to the loss of sensitivity of the female reproductive organ. It is due to the sexual dysfunction that women feels disinterested in the sex. This makes its difficult for the pregnancy to occur. It is necessary for the couple to have sex at least twice in a week to bore a child. But due to the women’s disinterest, couples don’t have sex for months. This results in pregnancy failures.

Remember that all the above mentioned conditions are 100% curable and there also some techniques like sperm transplantations that can also be used to make you pregnant. Thus, don’t get yourself stuck-up with these problems in pregnancy and don’t keep yourself abide from the wonderful experience of motherhood.

Infertility Frustrations?

While some women are able to get pregnant rather easily, many others have great difficulty. Infertility is not uncommon; fortunately, there are some things women can do to increase their chances of boosting their fertility.

According to the Centers of Disease Control and Prevention, 6% of married women aged 15 to 44 are infertile, and 7.4 million of all women in that age bracket have used infertility services.

If you are a woman who is trying to conceive and who meets any of the conditions listed below, you should consider making an appointment with a fertility specialist to discuss your options. A fertility expert can also help women who have had unprompted miscarriages.

Infertility Conditions & Causes

Each of the following circumstances officially defines infertility:

• Inability to become pregnant after one year of trying
• Irregular menstrual cycles (no cycle, no egg)
• Women who are 35 or older and have not conceived after 6 months of trying.

There are myriad causes of infertility, but the most common in women include:

• Early menopause
• Ovulation maladies
• Endometriosis
• Damage or blockage of the fallopian tube
• Increased level of prolactin
• Fibroids
• Polycystic ovary syndrome
• Thyroid problems
• Pelvic adhesions
• STDs

Things that Increase Your Infertility

Lifestyle certainly plays a role in infertility. The older a woman gets, the more difficult it is to conceive. With the increasing number of American women (20%) who wait until they are 30-something to think about parenthood, the cases of infertility in women will surly increase as well.

The CDC reports approximately one-third of women over 35 who are trying to conceive experience infertility. Age seems to be the leader factor why a woman is unable to get pregnant.

With age, the likelihood of miscarriage and genetic problems also increases. In some cases when pregnancy does occur, women can have difficulty bringing the child to full term.

While women seeking to conceive can't do much about the age of their ovaries and eggs, they should avoid the following:

• Smoking
• Excessive use of alcohol
• Excessive weight gain or loss
• Excessive stress either physical or emotional (which can result in absent periods).

It is also advisable to avoid, or at least reduce, caffeine intake. Studies have also shown that ovulation problems are associated with individuals exercising for more than 7 hours per week.

Increasing Your Fertility

Just as there are conditions that increase infertility, there are also actions you can take to increase your ability to get pregnant. It is natural for women to want to do everything possible to increase chances of pregnancy before seeking a fertility specialist.

Eat Healthy Foods

Eating a healthy diet is important for ovulation. Women trying to conceive should be mindful of the following:

• Eat less trans fats and more monounsaturated fats (like olive oil).
• Eat less red meat animal protein and more vegetable protein (like soy).
• Eat less refined sugars and carbohydrates and more high fiber, low-glycemic foods such as whole grains, vegetables, and some fruits.
• Eat moderate amounts of high-fat dairy products such as ice cream, whole milk, and cheese.

Control your Weight

Maintaining a healthy weight is helpful in making sure your cycles are regular as well as contributing to the overall health of your ovaries. The more irregular the body mass index (BMI), both higher and lower, the more a woman's ability to conceive is directly affected.

Reduce Stress

While highly debated, many physicians believe reducing stress positively enhances a woman's chances of pregnancy.

Ovulation

Tracking your ovulation cycle is very helpful in making sure you don't miss that prime-time window of opportunity. This method is especially helpful because sperm lives much longer than eggs. There are even OTC kits that assist you in determining when you are ovulating.

Conception Kits and Other Tests

Until recently, ovulation kits couldn't actually help you get pregnant. A kit is now available that not only helps you predict ovulation, it includes a small latex-free cervical cap to ejaculate in and is then inserted into the woman's cervix directly.

Think of it as a way to perform an at-home mini-insemination. Essentially, the procedure places the sperm where it needs to be without having to swim their way there.

If you are having difficulty getting pregnant, make an appointment with your gynecologist or fertility specialist for more information about your options. Long strides have been made in the fertility field, helping many people become parents.

Whether you're trying to get pregnant or are currently pregnant, it 's very important to consult with a board-certified obstetrician. Florida pregnancy care specialists at All About Women offer not only the highest quality, but the most compassionate care for this special time in your life.

Women Want Men With A Vasectomy

Having a vasectomy has been the wise choice of over five hundred thousand American men each year. This is because raising children has become less important to both men and women. There are many reasons for this change in values and the main one is economics--- it is too expensive to raise a child. It is estimated the cost of raising a child from birth until the age of eighteen runs over one hundred and fifty thousand dollars. This does not include the loss of income.

There are women that demand a potential lover get a vasectomy before they would be willing to have an affair with him. One attractive woman claims that she had seventeen lovers who had the operation done in order to get the chance to make love to her. She even paid the two hundred dollar cost of each operation out of her own pocket. The operations were done at the office of her private physician while she watched the hour long procedure. The doctor himself was one of her devotees who also had a vasectomy to get a chance to be her lover.

Men who are either unemployed or are on the low income scale are not recognized as husband material by most women. They would never consider raising a family with that type of individual. But he might be an attractive guy who she would like to have an affair with. There is now no reason for a woman to avoid a guy that is broke. She could ask him to get a vasectomy before he could become her lover. That is a sure way to prevent her from ever becoming a welfare mother.

Most health plans cover the costs of a vasectomy. Without health insurance doctors would do it for two hundred dollars. It is a wise choice for a guy that is having a hard time earning money. But remember to get a statement from the doctor. It will help your love life with a woman that has a fear of getting pregnant with a guy that is broke.

There are couples that have already had a few children and don’t want to have another one. The vasectomy would be the perfect solution. It is becoming the best way of keeping the family size contained to affordable levels.

Today’s women have a power never before dreamed of. They can control who the father of their child will be. A woman no longer has to take the chance of becoming pregnant with a guy that is sure to wind up as a dead beat dad--- a guy that can’t support his children and disappears. For two hundred bucks she can take him to her doctor and get him a vasectomy. If she decides her potential lover will make a good father than let it happen.

How to Practice Home Massage Techniques When Pregnant

More and more women are turning to alternative treatments for the aches and pains associated with pregnancy. This is largely thanks to a growing knowledge base, which tells us that alternative treatments are safer, for you and your baby.

Home massage is one of those types of treatment, and if you are interested in practising home massage while you are pregnant, then there are a few things you should know before hand.

Speak to Your Doctor

There are specific conditions that you may have while pregnant, that make some or all forms of home massage dangerous or unsafe.

If you’re considering making home massage a part of your ante natal treatment, make sure that you speak to your doctor first, and rule out all of those conditions first. It is always best to be safe, rather than sorry, and while home massage during pregnancy is usually perfectly safe, you need to be sure before you start!

Learn Proper Techniques

Home massage during pregnancy is not as simple as it is at other times. There are certain areas of your body that should be massaged in certain ways and specific techniques that should, and should not be used.

There are online courses, as well as real world training programs, that can help you to practice home massage during pregnancy safely, and with maximum benefit to you and your baby, and it is always a good idea to make sure that you know what you are doing before you incorporate it into your pregnancy routine.

Equip Yourself

If you are planning to make home massage a part of your pregnancy routine, then there are specific types of equipment and materials that can be useful. Heating and cooling pads, pregnancy safe massage oils and lotions; a firm and stable massage surface and other items are all things that you might like to consider. There are, of course, also many items that you probably already own that can be incorporated into home massage during pregnancy, and it need not be an expensive or difficult process.

Enlist Your Partner

During the early stages of your pregnancy, it may be possible to practice home massage techniques yourself, however, as you progress through your pregnancy, that will become more difficult. Enlist your partner’s help to massage your back, abdomen, and other areas of your body that you cannot reach. Not only does this make home massage during pregnancy easier, and more comfortable, but it allows your partner to become involved in the process of pregnancy, on a physical level.

Home massage is a great form of relaxation and therapy, as well as an effective treatment for many aches and pains, and it is a good idea to include it in your pregnancy routine from early on. Make sure that you do so safely, and that you stop if you notice any adverse or worrying effects and it should be a great way to relax and enjoy your pregnancy more.

Foods That Can Help You Get Pregnant Easily

Unknown to most women, there are some foods that can help you get pregnant easily. There are actually other factors to help you get pregnant fast and food is just one of them. What you eat can actually affect how fast you will conceive. This even applies to your partner, as it takes two to tango.

New findings indicate that your diet during pregnancy could even affect your chances of having either a baby girl or boy. In fact, research has discovered that expecting mothers who often had a high-calorie diet and ate breakfast regularly had more chances of giving birth to a baby boy. Scientists are suggesting that people being too busy for breakfast and having low calorie diets these days probably influence the increasing number of girls being born in recent years.

So how can food make one get pregnant easily? To date, there is proof established yet, but there is increasing evidence on the subject. In studies, those who took multivitamins that included folic acid or iron were found to have better chances of getting pregnant. It is also found that nutrients deriving from vegetables, fruits, beans and supplements in contrast to red meat, are able to boost fertility.

Watching Weight 
Experts suggest that anyone wanting to get pregnant easily should initially watch her weight. Women who have a BMI (body mass index) of 20 to 24 have the most likelihood of falling pregnant. On the other hand, women with a BMI over 24 or less than 20 have a less likelihood of conceiving. However, this definitely does not mean there's no hope for those who do not fall in the healthy weight category. Studies indicate that any woman can jump-start ovulation by making some healthy and moderate changes in their weight.

Organic Food 
So what foods can you try to get pregnant easily? There are a number of foods that are considered fertility boosting. Try to consume about 8 portions of organic fruits and vegetables each day. Go for organic when it comes to animal produce such as meat and dairy products. Consume more brown whole foods instead of white refined foods-whole foods contain more zinc, which is good for you. Moreover, you need to eat fewer portions but on a regular basis each day to maintain proper blood sugar levels in your body.

Fiber 
Don't forget your fiber, which is important in maintaining a healthy bowel and boosting fertility. Finally, eat more "good fats," which could be taken from oily fish like salmon, tuna and mackerel. You may take fish oil supplements or eat sunflower/pumpkin seeds, as mercury levels can be high in seafood. While you're at it, drink around 8 glass of water each day.

Foods To Avoid 
While there are foods that can help you get pregnant easily, there are those that you should avoid. Avoid drinking caffeine as much as possible. Also avoid drinking alcohol. These substances are known to present a risk of infertility in women.

Choose your diet well. Food has obviously been used as a source of nutrients for our well-being. But with so many choices these days, we need to choose the right kinds of food. Eating wisely can help any woman get pregnant easily.

Personalised Baby Gifts - The Perfect Way to Say Congratulations

Nine months. 38 weeks. 266-odd days. No matter how you break it down, being pregnant takes a while. And over that time, you've watched as she's got bigger and bigger. Then, finally, after a manic drive to the maternity ward, the world's presented with another little bundle of joy. It can only mean one thing - baby gift time.

In this instance, two things are a given. Number one - half of everybody who knows the new parents will buy Baby some cute clothes. You know the sort of thing - dinky jeans and a T-shirt with a cartoon helicopter on the front. Number two - the other half will buy Baby some brightly coloured toys, all of which will end up being chewed. And that's all well and good. But if you want to buck the trend, get online and shop for personalised baby gifts.

Kicking things off is something for mum and dad - personalised Champagne. After all, nothing says congratulations quite like our favourite French import. You'll be able to personalise the label with their names and a message dedicated to their newborn bub. It's a lovely touch, and far more personal than grabbing something in Sainsbury's during your big shop. What's more, with mum having gone cold turkey for the last eight months, it'll be a particularly big hit with her!

But what about if you're more interested in a personalised gift for Baby? A couple of options spring to mind. Firstly, there's a Tatty Teddy Message Bear. This cuddly little chap comes with a cream jumper that can be embroidered in either pink or blue. Any name can be added, in addition to three extra lines for a message. Super soft and very cute, he's the sort of bear that'll be sneaked up to the university halls in 18 years time.

The second alternative is a personalised baby blanket. Available in the classic baby pink and baby blue, they're made from a soft, durable fleece which can be personalising by adding Baby's name and either a message or their date of birth, both of which will then be embroidered onto the fleece. It all adds up to one seriously cute baby gift.

And of course, you've got all sorts of other gifts for babies to pick from, too - be it personalised picture frames, personalised newspaper covers or various china keepsakes. In fact, it just goes to show that when it comes to buying baby gifts, there's more to it than nipping down to Mothercare.
