Which of the following are gonadotrophins ?

Options

A. FSH + GH
B. LH + FSH
C. LH + GH
D. GH

Answer

To determine which hormones are gonadotropins, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Gonadotropins**: Gonadotropins are hormones that stimulate the activity of the gonads (ovaries and testes). They are primarily produced by the anterior pituitary gland.

2. **Identify the Source**: The anterior pituitary gland releases gonadotropins in response to signals from the hypothalamus. The hypothalamus releases Gonadotropin-Releasing Hormone (GnRH), which stimulates the anterior pituitary to produce gonadotropins.

3. **List the Gonadotropins**: The main gonadotropins produced by the anterior pituitary gland are:
- Follicle-Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)

4. **Understand Their Functions**:
- **FSH**: In males, it influences spermatogenesis (the production of sperm). In females, it is involved in the maturation of ovarian follicles.
- **LH**: In males, it stimulates the production of testosterone from Leydig cells. In females, it triggers ovulation and supports the corpus luteum.

5. **Analyze the Options**: Given the options in the question, we need to identify which of them include FSH and LH as these are the gonadotropins.

6. **Select the Correct Answer**: After reviewing the options:
- Option 1: FSH and GH (Growth Hormone) - Incorrect (GH is not a gonadotropin)
- Option 2: FSH and LH - Correct (Both are gonadotropins)
- Option 3: LH and GH - Incorrect (GH is not a gonadotropin)
- Option 4: GH - Incorrect (GH is not a gonadotropin)

Thus, the correct answer is **Option 2: FSH and LH**.
