What is Luteal phase.

Text Solution

Verified by Experts

The luteal phase is one stage of menstrual cycle. It occurs after ovulation. It begins with the formation of corpus luteum and ends in either pregnancy or luteolysis, i.e regression of corpus luteum. The main hormone associated with this stage is progesterone which is secreted by corpus luteum. This phase lasts between 10-16 days. Luteal phase of less than 12 days may make it difficult to achieve pregnancy.
