How is corpus leuteum formed?What is its function?how do copperT function?
The corpus luteum is what is left of the follicle after the ovulation process. During the follicular phase of a womans cycle, several follicles develop under the influence of FSH (follicle stimulating hormone). Each follicle contains an egg. In a typical cycle only one egg will become mature enough for ovulation. When a woman ovulates the egg will burst from the follicle. Then what is left of the follicle will become the corpus luteum.
The corpus luteum produces progesterone. Progesterone makes the lining of the uterus thick for implantation and is necessary to sustain a healthy pregnancy. The corpus luteum produces progesterone until the placenta begins to take over progesterone production around ten weeks gestation.
If the egg is not fertilized, the corpus luteum dies and progesterone production stops. When progesterone levels drop, the uterus lining stops thickening and is consequently shed during menstruation.
