Menstruation without ovulation. Because ovulation does not occur, the endometrium remains in the proliferative phase and does not change to the secretory phase due to progesterone, but bleeding occurs periodically. This is a physiological occurrence several years after menarche and several years before menopause, and is not pathological.

排卵を伴わない月経。排卵が起らないため,子宮内膜は増殖期の状態にとどまり,黄体ホルモンによる分泌期への変化も起らないが,周期的に出血する。初経後数年間と閉経の数年前では生理的に起るもので,病的なものではない。
