Question

Quizplus · Accepted Answer

Progestin-only pills thicken cervical mucus and make it harder for sperm to reach the egg. They also interfere with implantation, making it less likely that a fertilized egg will successfully implant in the uterus. While they may occasionally prevent the release of an egg, this is not their primary method of action. They do not kill sperm or create a physical barrier.
