Which one of the following is the correct matching of the events occurring during menstrual cycle?
Ovulation - LH and FSH attain peak level and sharp fall in the secretion of progesterone
Proliferative - Rapid regeneration of myometrium and maturation of Graafian follicle
Development of corpus - luteum - Secretory phase and increased secretion of progesterone
Development of corpus - luteum - Secretory phase and increased secretion of progesterone
C.
Development of corpus - luteum - Secretory phase and increased secretion of progesterone
In secretory phase during ovulation, the follicle breaks and collapses 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 fertilised egg by secreting oestrogens and progesterone.
