Select the correct match of endocrine gland, its hormone and its function

Options

A. Corpus luteum - estrogen -essential for maintenance of endometrium
B. Leydig cells - androgen - initiates production of sperms
C. Ovary - FSH - stimulates follicular development and secretion of estrogens
D. Pancreas - estrogen - initiates secretion of milk

Answer

To solve the question of matching the endocrine gland with its hormone and function, we will analyze each option provided and determine if they are correctly matched.

### Step-by-Step Solution:

1. **Identify the Endocrine Gland and Hormone:**
- **Option A:** Corpus Luteum → Progesterone
- **Option B:** Leydig Cells → Androgens (Testosterone)
- **Option C:** Ovaries → Estrogen
- **Option D:** Pancreas → Glucagon and Insulin

2. **Understand the Functions of Each Hormone:**
- **Progesterone (Option A):** This hormone is crucial for the maintenance of the endometrium during pregnancy.
- **Androgens (Testosterone) (Option B):** This hormone stimulates spermatogenesis, which is the production of sperm in males.
- **Estrogen (Option C):** This hormone is involved in the development of ovarian follicles and the regulation of the menstrual cycle.
- **Glucagon and Insulin (Option D):** These hormones regulate blood sugar levels, with insulin lowering blood sugar and glucagon raising it.

3. **Match Each Option with Its Function:**
- **Option A:** Correctly matched (Corpus Luteum → Progesterone → Maintenance of endometrium).
- **Option B:** Correctly matched (Leydig Cells → Androgens → Stimulates spermatogenesis).
- **Option C:** Partially correct (Ovaries → Estrogen → Development of ovarian follicles is stimulated by FSH, but estrogen itself is involved in broader functions).
- **Option D:** Correctly matched (Pancreas → Glucagon and Insulin → Regulates blood sugar levels).

4. **Determine the Best Match:**
- Based on the analysis, **Option B** (Leydig Cells → Androgens → Stimulates spermatogenesis) is a clear and direct match, making it the best answer.

### Final Answer:
The correct match of endocrine gland, its hormone, and its function is **Option B: Leydig Cells → Androgens (Testosterone) → Stimulates spermatogenesis.**
