The correct answer is 'ovulation and fertilisation'.

Key Points Oral contraceptive pills  or Hormones in birth control pills prevent pregnancy by:

  • Stopping or reducing ovulation (the release of an egg from an ovary) and fertilisation.
  • Thickening cervical mucus to keep sperm from entering the uterus.
  • Thinning the lining of the uterus so that a fertilized egg is less likely to attach.

Additional Information There are two different types of birth control pills. Both types contain hormones that prevent pregnancy.

  • Combination pills contain estrogen and progestin.
  • Progestin-only pills are also called “the minipill.” They’re better for some women, such as those who are breastfeeding or have a history of blood clots and strokes and shouldn’t take estrogen.
