Anovulation

Meaning

Anovulation is the clinical phenomenon where the ovaries fail to release an oocyte, or egg, during a menstrual cycle, signifying an absence of ovulation. This condition is a primary cause of infertility and is characterized by irregular or absent menstrual bleeding, known as amenorrhea or oligomenorrhea. Recognizing anovulation is vital in reproductive endocrinology, as it indicates a fundamental disruption in the hypothalamic-pituitary-ovarian axis signaling. Proper diagnosis requires careful assessment of hormonal markers and cycle tracking.
