It becomes the corpus luteum.
A regressing corpus luteum indicates that the egg was not fertilized. As the corpus luteum regresses it loses its capacity to produce progesterone. A regressed corpus luteum is termed as corpus albicans. The lack of progestorone, which leads to the shedding of the uterine lining, is responsible for the menstrual cycle.
The corpus luteum is located in the ovary.
The corpus luteum produces progesterone, which is a very important hormone for maintaining pregnancy. A corpus luteum or "yellow body" occurs after the mature follicle has been released from the ovum, then cells of the follicle change into the corpus luteum.
Prostaglandin F2alpha is the hormone responsible for triggering luteolysis, the regression of the corpus luteum in the ovary. This process leads to the cessation of progesterone production in non-pregnant animals.
corpus luteum
Progesterone is the primary hormone produced in the corpus luteum. Secondary is estrogen.
The corpus luteum is the area from which the mature egg broke free from the ovary during ovulation. The corpus luteum produces progesterone which is responsible for the uterine lining build-up.

The corpus luteum prepares to become a corpus albicans
The corpus luteum degenerates when the placenta is fully formed because the placenta takes over the production of hormones, particularly progesterone, that are necessary to maintain the pregnancy. Initially, the corpus luteum produces these hormones to support the early stages of pregnancy, but once the placenta is established and functional, it secretes sufficient hormones to sustain the pregnancy independently. This transition reduces the need for the corpus luteum, leading to its degeneration.
