The most common causes of irregular ovulation

The most common causes of irregular ovulation

There are more and more women who suffer from irregular ovulation. In some cases, they experience complete loss of ovulation during their reproductive age.

The problems arise mainly due to the lack of one of hormones responsible for the ovulation control. They are called follicle-stimulating hormone (FSH) and luteinizing hormone (LH).  Discontinuation of hormonal contraceptives after a long period can also cause ovulation dysfunction.

The ovulation problems are as complex as the ovulation cycle itself - even the smallest hormonal and other imbalances can have an important effect. That includes, for example, weight loss, long-term stress or prior infections. Another cause of ovulation dysfunction is hyperandrogenic syndrome which is an increased level of male hormones (often associated with the polycystic ovary syndrome).

To determine ovulation, specialists used to measure basal temperature. However, they agreed that this method is unreliable and slow. Today, ovulation tests, follicle ultrasound  (tracks the activity of the ovaries; ovulation occurs on the basis of the quantity and size of follicles) and hormone tests are used.

Over 40 % of couples are unable to conceive a child just because of the ovulation dysfunction. There are cases where, despite thorough examination, the cause fails to be identified. However, most women usually have a very good chance of getting pregnant thanks to an intervention of specialists.
