Polycystic ovarian syndrome is one of the most common conditions that otherwise healthy woman can suffer from. As you describe, it leads to an imbalance in circulating body hormones, the most obvious effect of which is that it causes irregular and sometimes heavy menstrual cycles.
For many people, polycystic ovarian syndrome also is a major cause of fertility. This is because those "irregular periods" occur because of cycles in which an egg follicle develops but does not get released. Since ovulation is unpredictable, so too is fertility and getting pregnant.
Luckily, several things are available to help you out. Sometimes birth control pills can be used to normalize the ovaries' cycle, helping with pregnancy. Also a common diabetes medication, metformin, is often used to encourage ovulation. There are also more advanced techniques available from your
OB GYN doctor if these do not work.
Maintaining a health weight and exercising frequently are important, as many women with PCOS tend to be overweight or be at risk of becoming overweight. Not only does this increase fertility, but it also protects against other possible long term complications of PCOS, such as developing diabetes,
high blood pressure, and other chronic conditions later in the course of your life.
