Corpus luteum in pregnancy has a long life. However, if Fertilisation does not take place, it remains active only for 10-12 days. Explain.
Answers (1)
During ovulation, the Graafian follicle breaks open, releasing the secondary oocyte. The remaining cells of the Graafian follicle transform into a structure called the corpus luteum. Corpus luteum is responsible for the secretion of progesterone, which is essential to maintain the endometrium and helps in the proper development of the foetus.This is the reason for the long life of Corpus luteum when Fertilisation has occurred. However, when there is no fertilisation, it serves no purpose and thus remains active only for 10-12 days
