Name the hormone and its source organ responsible for the events occurring during proliferative phase of menstrual cycle. Explain the event.

Ans.

Hormone responsible: Estrogen Source organ: Developing ovarian follicles

Events during the proliferative phase:

  1. Rise in estrogen levels

  2. Stimulation of endometrial lining proliferation and growth

  3. Thickening and increased vascularity of the endometrium

  4. Production of nutrient-rich secretion by endometrial glands

  5. Thin, clear, and stretchy cervical mucus facilitating sperm movement

Overall, estrogen stimulates the preparation of the uterine lining for potential embryo implantation during the proliferative phase of the menstrual cycle.
