Luteal Phase

The luteal phase is the second half of a woman’s menstrual cycle, typically lasting about 14 days. After ovulation, the ovary produces a structure called the corpus luteum, which releases hormones like progesterone. These hormones prepare the uterus for possible pregnancy by thickening its lining. If pregnancy does not occur, hormone levels decline, leading to menstruation and the start of a new cycle. The luteal phase is crucial for fertility because it supports early pregnancy, and its proper functioning is essential for conception and maintaining pregnancy.
