Which of the following is correctly matched :

Options

A. Testosterone-Can be used as contraceptive in females
B. Progesterone-Endometrial hyperplasia
C. Estrogen-Increase secretion of endometrium
D. FSH-Promotes estrogen synthesis and secretion

Answer

To solve the question "Which of the following is correctly matched?", we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option A: Testosterone can be used as a contraceptive in females.**
- Testosterone does have contraceptive properties in females. It works by suppressing the secretion of FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone), which are crucial for the maturation of ovarian follicles. Thus, this statement is **correct**.

2. **Option B: Progesterone leads to endometrial hyperplasia.**
- This statement is **incorrect**. Endometrial hyperplasia occurs when there is an excess of estrogen without sufficient progesterone. Progesterone actually helps to stabilize the endometrium and prevent hyperplasia. Therefore, this option is **wrong**.

3. **Option C: Estrogen increases secretion of endometrium.**
- This statement is also **incorrect**. While estrogen does promote the growth of the endometrium, it is progesterone that is primarily responsible for maintaining the endometrium after ovulation. Therefore, this option is **wrong**.

4. **Option D: FSH promotes estrogen synthesis and secretion.**
- This statement is **incorrect**. FSH is indeed important for the maturation of ovarian follicles, but it does not directly promote estrogen synthesis and secretion. Estrogen is produced by the ovarian follicles under the influence of FSH, but FSH itself does not promote the synthesis. Therefore, this option is **wrong**.

### Conclusion:
The only correct statement is **Option A: Testosterone can be used as a contraceptive in females**.
