Luteal phase

Luteal Phase

The Luteal phase is a stage in the menstrual cycle that occurs after ovulation and before the start of a woman's next period. It typically lasts about 14 days and ends just before the next menstrual period begins.

Overview

The luteal phase begins after ovulation, when the corpus luteum forms in the ovary. The corpus luteum is responsible for the production of the hormone progesterone, which prepares the endometrium (the lining of the uterus) for the potential implantation of a fertilized egg.

Hormonal Changes

During the luteal phase, the levels of estrogen and progesterone increase to thicken the endometrium. If fertilization does not occur, the corpus luteum degenerates and the levels of these hormones decrease. This leads to the shedding of the endometrium, or menstruation.

Luteal Phase Defect

A Luteal Phase Defect (LPD) is a condition characterized by an inadequate luteal phase, either in terms of length or function. This can lead to difficulties in achieving or maintaining a pregnancy.

Treatment

Treatment for LPD typically involves hormone therapy to increase the levels of progesterone. This can be done through the use of progesterone supplements or fertility drugs.
