During luteal phase, which hormone stimulates the uterine glands to produce watery mucus?

Options

A. Progesterone
B. FSH
C. LH
D. GnRH

Answer

**Step-by-Step Solution:**

1. **Understand the Luteal Phase**: The luteal phase is a part of the menstrual cycle that occurs after ovulation and before the start of menstruation. It is characterized by the formation of the corpus luteum.

2. **Identify the Role of Corpus Luteum**: The corpus luteum is formed from the remnants of the follicle after ovulation. Its main function is to produce hormones, particularly progesterone.

3. **Function of Progesterone**: During the luteal phase, progesterone plays a crucial role in preparing the endometrium (the inner lining of the uterus) for potential implantation of a fertilized egg.

4. **Effect on Uterine Glands**: Progesterone acts on the uterine glands, stimulating them to produce secretions that are essential for creating a suitable environment for implantation.

5. **Type of Mucus Produced**: The uterine glands produce a watery mucus in response to the action of progesterone. This mucus helps in nourishing the fertilized egg and supports early pregnancy.

6. **Conclusion**: Therefore, the hormone that stimulates the uterine glands to produce watery mucus during the luteal phase is progesterone.

**Final Answer**: Progesterone.
