How many days approximately the corpus luteum of menstruation persists after ovulation?
The fate of the corpus luteum depends on whether a pregnancy occurs. Following the LH surge, the corpus luteum is programmed to secrete progesterone for 10-12 days. Without fuher LH stimulation and in the absence of pregnancy, both major cell types of the corpus luteum cease steroid production and undergo apoptosis while the tissue regresses. The corpus luteum that persists for pa of only one menstrual cycle is called a corpus luteum of menstruation. Remnants from its degeneration and regression are phagocytosed by macrophages, after which fibroblasts invade the area and produce a scar of dense connective tissue called corpus albicans.
