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.f 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. If the egg is fertilized, the corpus luteum will begin receiving HCG from the embryo.
The corpus luteum is made up of lutein cells (from the Latin luteus, meaning âsaffron-yellowâ), which develop immediately following ovulation, when yellow pigment and lipids accumulate within the granulosa cells lining the follicle. The size of the corpus luteum is highly variable.
