Which of the following hormone/s is/are maintained at high level during hormonal method of birth control ?

Options

A. FSH
B. LH
C. Progesterone
D. Both (1) & (2)

Answer

### Step-by-Step Solution:

1. **Understanding Hormonal Birth Control**:
- Hormonal methods of birth control are commonly used by females to prevent pregnancy. These methods typically involve the use of hormonal pills or injections.

2. **Identifying the Hormones Involved**:
- The primary hormones involved in hormonal birth control are **progesterone** and **estrogen**. These hormones can be present alone or in combination in contraceptive pills.

3. **Role of Progesterone**:
- Progesterone is crucial in hormonal contraceptives. It helps to inhibit ovulation (the release of an egg from the ovaries) and prevents the implantation of a fertilized egg in the uterus.

4. **Understanding the Mechanism**:
- By maintaining high levels of progesterone, these contraceptive methods effectively prevent ovulation and reduce the chances of fertilization and implantation.

5. **Duration of Usage**:
- Oral contraceptive pills are usually taken for a duration of 21 days, starting from the first five days of the menstrual cycle.

6. **Other Hormones**:
- Other hormones such as Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) play roles in the menstrual cycle but are not maintained at high levels during hormonal birth control. In fact, the presence of high levels of progesterone can suppress the peaks of these hormones, particularly LH, which is responsible for triggering ovulation.

7. **Conclusion**:
- The hormone that is maintained at high levels during the hormonal method of birth control is **progesterone**.

### Final Answer:
- **Progesterone** is the hormone maintained at high levels during hormonal methods of birth control.
