Menstrual cycle

From IKE

The menstrual cycle is the cycle by which the reproductive female experiences menses, the ultimate goal of which is ovulation and pregnancy. The cycle has four main phases: follicular (proliferative), ovulatory, luteal (secretory), and menstrual.

A normal menstrual cycle may last between 21 and 35 days, with 3 to 10 days of menses and up to 80mL of blood lost per cycle.

Problems

Irregular patterns of bleeding include menorrhagia, hypomenorrhea, polymenorrhea, metrorrhagia, oligomenorrhea, amenorrhea, and menometorrhagia.
