Oral contraceptives contain :-

Options

A. Progesterone
B. LH
C. Oxytocin
D. Steroles

Answer

**Step-by-Step Solution:**

1. **Understanding Oral Contraceptives**: Oral contraceptives are medications taken by women to prevent pregnancy. They are commonly referred to as "the pill."

2. **Types of Oral Contraceptives**: There are two main types of oral contraceptives:
- **Mini Pills**: These contain only the hormone progesterone.
- **Combined Pills**: These contain both estrogen and progesterone.

3. **Mechanism of Action**: The primary function of these pills is to prevent conception. They can do this by:
- Preventing ovulation (the release of an egg from the ovaries).
- Preventing implantation of a fertilized egg in the uterus.
- Altering the quality of cervical mucus to impede sperm entry into the female reproductive tract.

4. **Identifying the Correct Hormone**: The question asks what oral contraceptives contain. The key hormones involved in these pills are:
- **Progesterone**: Found in mini pills and combined pills.
- **Estrogen**: Found only in combined pills.
- Other options like LH (luteinizing hormone) and oxytocin are not components of oral contraceptives.

5. **Conclusion**: The correct answer is that oral contraceptives contain progesterone (and sometimes estrogen in combined pills). However, since the question specifically asks about the main component, progesterone is the most relevant answer.

**Final Answer**: Oral contraceptives contain progesterone (and may also contain estrogen in combined pills).
