Which of the following methods of contreception prevents ovulation?

Options

A. Pills
B. Depo-provera
C. Norplant
D. All the above

Answer

To determine which methods of contraception prevent ovulation, we can analyze each option provided:

1. **Pills (Oral Contraceptive Pills)**:
- These pills contain hormones, primarily estrogen and progesterone.
- They work by inhibiting the release of eggs from the ovaries (ovulation).
- Therefore, this method effectively prevents ovulation.

2. **Depo-Provera (Injection)**:
- Depo-Provera is a hormonal injection that also prevents ovulation.
- It contains a form of progesterone, which stops the ovaries from releasing eggs.
- Thus, this method is also effective in preventing ovulation.

3. **Nexplanon (Implant)**:
- Nexplanon is a small rod that is implanted under the skin and releases hormones.
- It primarily releases progesterone, which prevents ovulation by inhibiting the release of eggs from the ovaries.
- Therefore, this method also prevents ovulation.

4. **All of the Above**:
- Since all the methods listed (pills, Depo-Provera, and Nexplanon) prevent ovulation, this option is correct.

Based on the analysis, the correct answer is **Option 4: All of the Above**.
