Pronunciation: an-OV-yuh-lay-shun
The absence of ovulation in a menstrual cycle. A key diagnostic finding in fertility assessments.
Full Definition
Anovulation refers to menstrual cycles in which the ovaries do not release an oocyte. This condition can be temporary or chronic and is a major cause of female infertility. It can result from various factors including hormonal imbalances, stress, extreme weight changes, or underlying medical conditions such as thyroid disorders. Diagnosis typically involves tracking ovulation through various methods including basal body temperature charts, ovulation predictor kits, or hormonal testing.
Usage
Usage note: Often confused with amenorrhea; anovulation specifically refers to lack of ovulation while menstruation may still occur.
