Triple Contraceptive Action of the Pill

The contraceptive pill offers a triple protection mechanism for reliable contraception:

  1. Effectively Inhibits Ovulation – Prevents the release of eggs.
  2. Thickens Cervical Mucus – Makes it difficult for sperm to enter the uterus.
  3. Changes Endometrial Thickness – Makes it hard for a fertilized egg to implant.

This triple action makes the pill a reliable choice for many, but consult a doctor to ensure it suits your individual needs.
