Question

Explain how the intake of oral contraceptive pills prevent pregnancy in humans.

Hint:

Copper IUDs provide long-term, reversible contraception by creating an inhospitable environment for sperm and preventing implantation. Oral contraceptives work by regulating hormonal levels, inhibiting ovulation, and making the cervix less permeable to sperm.

Answer 1

How the intake of oral contraceptive pills prevent pregnancy in humans:
- Oral contraceptive pills contain synthetic hormones (typically a combination of estrogen and progesterone) that work in several ways to prevent pregnancy:
1. Inhibition of ovulation:
- The hormones prevent the release of eggs from the ovaries, making ovulation impossible.
2. Thickening of cervical mucus:
- The pills cause the mucus in the cervix to thicken, which blocks the entry of sperm into the uterus.
3. Altering the uterine lining:
- They also alter the lining of the uterus, making it less likely for a fertilized egg to implant.
