MDCAT Biology QUESTION #11391
Question 1
During the menstrual cycle, after the female gamete is released from the ovary in the ovulation, the remains of the ovary is:
  • FSH
  • LH
  • Corpus luteum✔️
  • Testosterone
Correct Answer Explanation
After ovulation, the ruptured follicle transforms into the corpus luteum ('yellow body'). Under LH stimulation, the corpus luteum secretes progesterone and estrogen to maintain the uterine lining for potential implantation. If fertilization does not occur, the corpus luteum degenerates (corpus albicans) and hormone levels fall, triggering menstruation.
