Progesterone hormone is active during:
Correct answer: C. Secretory phase
- A. Follicular phase
- B. Menstrual phase
- C. Secretory phase
- D. Proliferative phase
Explanation
The secretory phase occurs after ovulation and is also known as the luteal phase. During this phase, the ruptured follicle transforms into the corpus luteum, which produces progesterone. Progesterone plays a crucial role in preparing the uterine lining to support a potential pregnancy. If fertilization and implantation of an embryo occur, the corpus luteum continues to produce progesterone. If no pregnancy occurs, the corpus luteum regresses, leading to a decline in progesterone levels.

The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
