Luteal Phase

The luteal phase is the second stage of the menstrual cycle, which begins after menstruation and ends 13-15 days after ovulation. During the luteal phase, the corpus luteum is still functioning and produces progesterone. If pregnancy does not occur, it transforms into a white body, is replaced by connective tissue and stops working.

Luteal stage - one

The luteal phase is the last and longest phase of the menstrual cycle in women, occurring immediately after ovulation and lasting until the start of the next menstruation. It is caused by the activity of the corpus luteum - a temporary endocrine gland that forms at the site of a ruptured follicle after ovulation.

The luteal phase begins on the day when the egg leaves the follicle that ruptured the day before and ends the existence of the corpus luteum. During this phase, the uterus of the unborn child is formed: it greatly increases. After 4-7 days, its walls grow, thicken and become loosely fibrous, and the cervical canal expands and the lumens expand sharply. The uterus rises from the pelvic cavity below and protrudes above the womb (“baby place” compared to the “uterine udder”). The edges of the uterus are moving closer together. The upper part of the uterus is shaped like the number 2 or 3. MU - the lumen of their cavity, expanded by the lumen (here the fertilized egg), filled with liquid, protects the uterine cavity from possible mechanical damage and stretching, providing optimal conditions for conception.
