The corpus luteum is formed from the ovary. The pituitary gland increases its production of the second hormone, luteinizing hormone (LH). This second hormone allows the mature egg to rupture from the ovary (called ovulation) and enter into the uterine tube. The postovulatory phase has begun. LH also encourages the formation of a "scar" within the ovary. This "scar" is called the corpus luteum, and it produces the hormone progesterone.
A corpus luteum is a hormone-secreting structure that develops in an ovary. It develops after an ovum has been discharged, but degenerates after a few days unless pregnancy has begun.
From a follicle after ovulation
ovary
The corpus luteum is located in the ovary.
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 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.
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.
Lutein cells are the glandular-epithelial cells forming the outer layer of the corpus luteum. They develop from cells of the Graafian follicle.
corpus luteum
Progesterone is the primary hormone produced in the corpus luteum. Secondary is estrogen.
The main function of the corpus luteum is to produce progesterone, which increases the body temperature in preparation for the fertilized egg. Therefore, without a functioning corpus luteum there would be no increase in progesterone or temperature.
The corpus luteum prepares to become a corpus albicans
The corpus luteum produces progesterone during the time that the placenta is forming, about the first trimester. After the placenta is mature, it will continue to produce progesterone while the corpus luteum degenerates. Progesterone is an important pregnancy hormone. Pregnancy cannot continue without it.
