Luteal Phase

Meaning

The luteal phase represents the post-ovulatory stage of the menstrual cycle, commencing immediately after ovulation and concluding with either the onset of menstruation or the establishment of pregnancy. During this critical period, the ruptured ovarian follicle transforms into the corpus luteum, a temporary endocrine gland responsible for producing the hormone progesterone, along with a lesser amount of estradiol. This hormonal shift is essential for preparing the uterine lining for potential embryo implantation.
