What is the Meaning of Luteal Phase?

The second half of the female reproductive cycle, occurring after ovulation and culminating in menstruation or implantation, during which the corpus luteum secretes significant amounts of progesterone. This phase is characterized by elevated basal body temperature and preparation of the endometrium for potential pregnancy. It is critically regulated by the preceding LH surge.

What is the Origin of Luteal Phase?

Derived from Latin, 'luteus' meaning yellow, referring to the yellowish appearance of the corpus luteum, the structure that dominates this phase in the ovary. This phase is a fundamental component of the ovarian cycle, first characterized through anatomical and histological study. It represents the post-ovulatory hormonal shift.

What is the Mechanism of Luteal Phase?

Following the LH surge, the ruptured follicle transforms into the corpus luteum, which is primarily responsible for synthesizing and releasing progesterone under continued LH and prolactin support. Progesterone acts on target tissues, notably the endometrium, promoting secretory changes and maintaining uterine lining stability. Should fertilization not occur, the corpus luteum regresses, leading to a drop in progesterone and the initiation of menses.
