Estrogen and fertility are inextricably bound together.
Without the right and precise amount of estrogen there can be no fertility.
Women who suffer from lack of fertility can very often trace this to either a lack of estrogen or a glut of it.
Estrogen based fertility problems are very often capable of being resolved quite easily and should not be allowed to induce despair of ever getting pregnant.
Without being too technical, and in plain English as far as possible, let's look at the role of estrogen in the female fertility cycle.
The pituitary gland produces a hormone commonly referred to as FSH.
This is sent out to tell the ovary to make estrogen so that an egg can be made ready for ovulation and the menstrual cycle can begin.
But it doesn't always happen.
The reason is usually too little estrogen, although sometimes it can be too much.
Estrogen is a family of ovarian hormones, all with similar characteristics, and playing a vital role in fertility.
It has to be produced in very strictly controlled amounts, and the hormone that controls the amount produced is known as LH (Luteinizing Hormone).
It only takes a few nanograms off the precise amount required to cause infertility.
The trouble is that the pituitary gland, where it all starts, is very sensitive and can be adversely affected by a number of things, including excessive exercise, body weight and eating habits.
Excessive exercise can lead to a loss of body weight, as can eating insufficiently.
This in turn can trigger the pituitary gland into producing low levels of estrogen.
Conversely, lack of exercise or eating to excess (or both) can lead to excessive body fat, and this can fool the pituitary gland into producing too much estrogen.
Lack of estrogen very often leads to hot flashes, night sweats, headaches (and even migraines) and vaginal dryness.
This latter condition alone means coping with infertility, even if only temporarily, as it invariably means the uterus lining is thin and incapable of sustaining a fertilised ovum.
Often ovulation doesn't even take place owing to this inhospitable environment.
If this happens the pituitary gland sends out more and more FSH in an attempt to stimulate the ovary whose turn it is to produce an egg, rather like putting on too much fertiliser when you don't have enough flowers growing in your garden.
This causes even more imbalance in the delicate hormonal makeup and makes matters worse.
If the ovaries cannot produce good quality eggs, or produce no eggs at all, then the level of estrogen is kept too low, or is even non-existent.
In cases of obesity the pituitary gland is prompted to produce too much estrogen, resulting in conditions in the uterus, such as benign growths, that are hostile to a fertilised ovum.
In most cases of infertility that result from abnormal levels of estrogen there is a solution.
The amount of exercise taken, and the quality and amount of food eaten can be controlled fairly easily.
Often this is all that is necessary.
Where, however, there is still a lack of estrogen then estrogen-rich medication is available that can induce further production.
The trouble here is the need for your body to produce the precise amount of estrogen required, and no more.
In summary, lack of estrogen can often be treated by entirely natural means.
If you can maintain a balanced diet and engage in sufficient, though not excessive, exercise, then you have an excellent chance of nursing your reproductive system back to full fertility.
