The gonadotropic hormones are secreted by

Options

A. aneterior lobe of pituitary
B. intersttitial cells of testes
C. aderenal cortex
D. posterior part of thyroid.

Answer

**Step-by-Step Solution:**

1. **Understanding Gonadotropic Hormones**: Gonadotropic hormones are hormones that specifically act on the gonads (the reproductive organs). The primary gonadotropic hormones are Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH).

2. **Identifying the Source**: To answer the question, we need to identify which gland secretes these hormones. The main gland responsible for the secretion of LH and FSH is the pituitary gland.

3. **Differentiating Pituitary Lobes**: The pituitary gland has two main lobes: the anterior (front) lobe and the posterior (back) lobe. The anterior lobe is responsible for producing and releasing several hormones, including LH and FSH.

4. **Reviewing Other Options**:
- Interstitial cells of the testes primarily produce testosterone and progesterone, not gonadotropic hormones.
- The adrenal cortex secretes hormones like cortisol and aldosterone, which are not gonadotropic.
- The posterior part of the thyroid gland releases hormones like T3 and T4, which are also not gonadotropic.

5. **Conclusion**: Based on the information gathered, the gonadotropic hormones (LH and FSH) are secreted by the anterior lobe of the pituitary gland.

**Final Answer**: The gonadotropic hormones are secreted by the anterior lobe of the pituitary gland.
