- CDevelopment of corpus luteum - Secretory phase and corpusluteum increased secretion of progesterone
- DMenstruation - Breakdown of myometrium and ovum
Correct answer
C. Development of corpus luteum - Secretory phase and corpusluteum increased secretion of progesterone
Step-by-step solution
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 fertilized egg by secreting estrogens and progesterone.
