FSH is secreted by

Options

A. anterior lobe of pituitary
B. hypothalamus
C. gonads
D. posterior lobe of pituitary.

Answer

**Step-by-Step Solution:**

1. **Understanding FSH**: FSH stands for Follicle Stimulating Hormone. It is a hormone that plays a crucial role in the reproductive processes of both males and females.

2. **Identifying the Source**: To determine where FSH is secreted from, we need to look at the glands involved in hormone production. The options provided are:
- Anterior lobe of pituitary
- Hypothalamus
- Gonads
- Posterior lobe of pituitary

3. **Analyzing Each Option**:
- **Hypothalamus**: This gland produces releasing hormones like GnRH (Gonadotropin-Releasing Hormone) that stimulate the pituitary gland but does not directly secrete FSH.
- **Gonads**: These are the reproductive organs (ovaries in females and testes in males) that produce sex hormones like testosterone and progesterone but do not secrete FSH.
- **Posterior lobe of pituitary**: This lobe secretes hormones like vasopressin and oxytocin but does not produce FSH.
- **Anterior lobe of pituitary**: This lobe is responsible for the secretion of several hormones, including FSH, LH (Luteinizing Hormone), TSH (Thyroid Stimulating Hormone), GH (Growth Hormone), and Prolactin.

4. **Conclusion**: After analyzing all the options, it is clear that FSH is secreted by the anterior lobe of the pituitary gland.

5. **Final Answer**: Therefore, the answer to the question "FSH is secreted by" is the **anterior lobe of the pituitary gland**.
