anovulation
Pronunciation: an-oh-vyuh-LAY-shun
The absence of ovulation in a menstrual cycle, a common cause of female infertility requiring specific treatment approaches.
Full Definition
Anovulation is the medical condition characterized by the absence of ovulation during menstrual cycles, meaning no oocyte is released from the ovarian follicles. This condition is a significant cause of female infertility and can be associated with irregular menstrual cycles, absent periods (amenorrhea), or apparently normal but non-ovulatory cycles. Anovulation can be caused by various factors including hormonal imbalances, polycystic ovary syndrome, thyroid disorders, excessive exercise, stress, or significant weight changes. Diagnosis typically involves hormone testing, ovulation monitoring, and ultrasound assessment. Treatment approaches depend on the underlying cause and may include ovulation induction medications, lifestyle modifications, or hormonal therapies to restore normal ovulatory function.
Usage
Usage note: Distinguish from oligoovulation (infrequent ovulation) and amenorrhea (absent menstruation).
