Ovulation – LH and FSH attain peak level and sharp fall in the secretion of progesterone |
b) |
Proliferative phase – Rapid regeneration of myometrium and maturation of Graafian follicle |
|
c) |
Development of corpus luteum – Secretory phase and increased secretion of progesterone |
d) |
Menstruation – Breakdown of myometrium and ovum not fertilized |

(c)
In secretory phase during ovulation, the follicle breaks and collapse under the continuous influence of Luteinizing Hormone (LH). It begins to enlarge and forms a yellowish structure, called the corpus luteum. The corpus luteum plays an important role in the preparation of the endometrium for the implantation of the fertilized egg by secreting estrogens and progesterone.
