Plan B Emergency Contraceptive Pill

Understanding the Science Behind Plan B Emergency Contraceptive Pill

The effectiveness of the Plan B emergency contraceptive pill is rooted in its ability to intervene in the potential fertilization process. Here’s a brief breakdown of how it operates:

Delay in Ovulation: The active ingredient in Plan B, levonorgestrel, works primarily by preventing the release of an egg from the ovary. By delaying ovulation, it ensures that there’s no egg available for a sperm to fertilize.

Alteration of Cervical Mucus: Plan B may also increase the thickness of the cervical mucus. This makes it more challenging for sperm to move through the cervix and reach an egg, reducing the chances of fertilization.

Possible Alteration of Uterine Lining: There’s some evidence to suggest that Plan B might alter the lining of the uterus, making it less receptive to a fertilized egg. However, this is still a topic of research.

It’s crucial to understand that Plan B does not terminate an existing pregnancy. It acts proactively to prevent a potential pregnancy from occurring.

Timing is Essential

The sooner Plan B is taken after unprotected intercourse, the higher its effectiveness. It is most effective when taken within the first 24 hours but can be used up to 72 hours after.

Recommended Use

Plan B® helps prevent pregnancy after unprotected sex (if a contraceptive failed or you did not use birth control).
