The growth of corpus luteum is initiated by
(a) human chorionic gonadotropin
(b) follicle stimulating hormone
(c) luteinizing hormone
(d) prolactin
Answers
Answer:
follicle stimulating hormone
Option ( c)
Corpus luteum, yellow hormone-secreting body in the female reproductive system. It is formed in an ovary at the site of a follicle, or sac, that has matured and released its ovum, or egg, in the process known as ovulation. The corpus luteum is made up of lutein cells (from the Latin luteus, meaning “saffron-yellow”), which develop immediately following ovulation, when yellow pigment and lipids accumulate within the granulosa cells lining the follicle.

The steps of ovulation, beginning with a dormant primordial follicle that grows and matures and is eventually released from the ovary into the fallopian tube.

m secretes estrogens and progesterone. The latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. If the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
