Question

• A. Eggs are released but no fertilisation
• B. Eggs are not released and no fertilisation
• C. No formation of eggs
• D. Lining of uterus breaks off

Answer 1

Answer:

B. Eggs are not released and no fertilisation

• Oral contraceptive pills primarily work by preventing the release of eggs (ovulation)and thickening the cervical mucus, making it difficult for sperm to reach the egg.

• Therefore, there is no egg release and no fertilization.

• Anovulation (also called an anovulatory cycle) happens when an egg doesn't release from your ovary (ovulation).

• Ovulation only happens one time during your menstrual cycle.

• The egg that your ovary releases at ovulation has the potential to be fertilized by sperm and create a pregnancy
