Which of the following is the component of oral pills?

Options

A. Progesterone
B. oxytocin
C. relaxin
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Oral Pills**: Oral pills are contraceptive medications taken by women to prevent pregnancy. They are commonly referred to as birth control pills.

2. **Types of Oral Pills**: There are two main types of oral contraceptive pills:
- **Simple Pills**: These contain only one hormone, which is progesterone.
- **Combined Pills**: These contain two hormones, estrogen and progesterone.

3. **Function of Progesterone**: Progesterone plays a crucial role in maintaining the endometrium (the lining of the uterus). When progesterone is administered externally through these pills, it mimics the hormonal state of pregnancy.

4. **Hormonal Effects**: The presence of progesterone leads to:
- Inhibition of Follicle Stimulating Hormone (FSH) release.
- Consequently, there is no release of Luteinizing Hormone (LH).
- The absence of LH prevents ovulation.
- Without ovulation, fertilization cannot occur.

5. **Identifying the Correct Component**: Among the options provided, the question asks for the component of oral pills. The correct answer is progesterone, as it is a key ingredient in both simple and combined oral contraceptive pills.

6. **Eliminating Incorrect Options**: Other options such as oxytocin and relaxin are hormones involved in childbirth and delivery but are not components of oral contraceptive pills.

**Final Answer**: The component of oral pills is **progesterone**.
