Final answer:
Growth of ovarian follicles is stimulated by FSH, while LH surge triggers ovulation and the formation of the corpus luteum, which secretes hormones to prepare the endometrium for implantation.
Step-by-step explanation:
The growth of follicles present in the ovary occurs under the effect of FSH (Follicle Stimulating Hormone). This follicle secretes estrogen. The endometrium grows/regenerates under the effect of estrogen. Under the effect of LH (Luteinizing Hormone), the fully grown follicle bursts, ovulation occurs, and the corpus luteum is formed from the remaining part of the follicle. It secretes progesterone and estrogen. Under the effect of these hormones, glands of the endometrium are activated and it becomes ready for implantation.
