What is the Corpus luteum?
The corpus luteum, latin for "yellow body", is a structure formed from the Graff follicle. The formation of this body takes place after ovulation, that is, when the secretory phase of the menstrual cycle begins.
The corpus luteum is responsible for producing estrogen and progesterone. For this reason, the corpus luteum becomes larger when the egg is fertilized and can thus release hormones to help in pregnancy. On the other hand, the corpus luteum degenerates if fertilization of the released egg does not take place.
