Ovulation in humans is controlled by

Options

A. FSH and LTH
B. FSH and TSH
C. LTH and LH
D. FSH and LH

Answer

**Step-by-Step Solution:**

1. **Understanding Ovulation**: Ovulation is the process in human females where an egg (ova) is released from the ovarian follicles. This is a crucial part of the menstrual cycle.

2. **Hormonal Control**: The process of ovulation is regulated by hormones. In particular, two key hormones are involved: Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

3. **Role of FSH**: FSH is secreted by the anterior pituitary gland. It is responsible for stimulating the growth of ovarian follicles in females, which is essential for the maturation of the eggs.

4. **Role of LH**: LH, also secreted by the anterior pituitary gland, plays a significant role in triggering ovulation. It stimulates the final maturation of the ovarian follicles and the release of the egg.

5. **Conclusion**: Both FSH and LH are crucial for the ovulation process. Therefore, the correct answer to the question "Ovulation in humans is controlled by" is FSH and LH.

6. **Evaluating Options**:
- Option A: FSH and LTH - Incorrect (LTH is not involved).
- Option B: FSH and TSH - Incorrect (TSH is not involved).
- Option C: LTH and LH - Incorrect (LTH is not involved).
- Option D: FSH and LH - Correct (both hormones are involved in ovulation).

**Final Answer**: Ovulation in humans is controlled by FSH and LH.
