'''Anovulation''' is when the ovaries do not release an [[oocyte]] during a [[menstrual cycle]]. Therefore, [[ovulation]] does not take place. However, a woman who does not ovulate at each menstrual cycle is not necessarily going through [[menopause]]. Chronic anovulation is a common cause of [[infertility]].

In addition to the alteration of menstrual periods and infertility, chronic anovulation can cause or exacerbate other long-term problems, such as [[androgen|hyperandrogenism]] or [[osteopenia]]. It plays a central role in the multiple imbalances and dysfunctions of [[polycystic ovary syndrome]].

During the first two years after [[menarche]] 50% of the menstrual cycles could be anovulatory cycles.

It is in fact possible to restore ovulation using appropriate medication, and ovulation is successfully restored in approximately 90% of cases. The first step is the diagnosis of anovulation. The identification of anovulation is not easy; contrary to what is commonly believed, women undergoing anovulation still have (more or less) regular periods. In general, women only notice that there is a problem once they have started trying to conceive.

Temperature charting is a useful way of providing early clues about anovulation, and can help gynaecologists in their diagnosis.
