 FSH and Fertility – A Simple Guide to the Relevance of FSH Readings

 

The link between FSH and fertility is something that many couples considering IVF treatment only vaguely understand. But in order to establish in your own mind what treatment fertility tarot reading is best for your body so as to increase your chances of conceiving a baby you really need to know how this aspect of your body works. So here is a simple explanation.

FSH governs the production of eggs in females and sperm in males, and a lack of quantity or quality in either may make that couple infertile. FSH readings are invariably taken on women undergoing or considering IVF treatment, and so this article refers to women rather than men.

We are primarily concerned with just two body organs – your hypothalamus gland and your pituitary gland. Your hypothalamus gland has been likened to a thermostat, except that instead of monitoring temperature it monitors your hormone level. This gland, at the appropriate time in each menstrual cycle, releases a hormone called the gonadotropin releasing hormone (GnRH), which in turn affects the pituitary gland.

The pituitary gland is responsible, among other things, for releasing hormones into the body at the required levels, so as to maintain fertility. Possibly the most important of these hormones is the follicle stimulating hormone (FSH), and it is this that is released as a result of the interaction of the GnRH on your pituitary gland. This FSH then stimulates the ovarian follicles (which contain the egg cells) into producing the hormones needed to enable and sustain pregnancy.

When you have difficulty conceiving one of the possible causes is that your pituitary gland is releasing an incorrect amount of FSH. Hence the need to monitor it. Measurements are normally taken on the second or third day of your cycle and the reading should be below 15 mIU/ml.

Between 15 and 25 is outside the normal range but does not necessarily mean you are infertile. Above 25, however, usually does mean you are, at least for the time being, infertile. Possibly your pituitary gland is trying, in its own way, to make up for an insufficiency elsewhere. This is usually in your “ovarian reserve”, i.e. the number and quality of eggs, or responsive follicles, remaining in your ovaries.
