Which one controls the secretion of oestrogen

Options

A. h CG
B. Progesterone
C. LH
D. FSH.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks which hormone controls the secretion of estrogen. Estrogen is a key female sex hormone involved in the regulation of the menstrual cycle and reproductive system.

2. **Identifying the Options**: The options provided are:
- HCG (Human Chorionic Gonadotropin)
- Progesterone
- LH (Luteinizing Hormone)
- FSH (Follicle Stimulating Hormone)

3. **Analyzing Each Option**:
- **HCG**: This hormone is secreted by the placenta during pregnancy and helps maintain the corpus luteum, but it does not directly control estrogen secretion.
- **Progesterone**: This is another female sex hormone that plays a role in maintaining the uterine lining but is not responsible for the secretion of estrogen.
- **LH**: Luteinizing Hormone is involved in the reproductive system and stimulates the growth of ovarian follicles, but it is not the primary hormone that controls estrogen secretion.
- **FSH**: Follicle Stimulating Hormone is secreted by the anterior pituitary gland and is crucial for the growth of ovarian follicles. It directly influences the ovarian follicles to produce estrogen.

4. **Conclusion**: Based on the analysis, the hormone that controls the secretion of estrogen is **FSH (Follicle Stimulating Hormone)**.

5. **Final Answer**: FSH (Follicle Stimulating Hormone)
