The lifespan of sperm inside a woman's body, even when she is on birth control, can be 5 to 7 days.
While birth control methods are designed to prevent pregnancy, they are not always 100% effective. Therefore, understanding sperm viability is crucial.
Here's a breakdown:
- Sperm Lifespan: Sperm can survive in the female reproductive tract for up to 5 to 7 days.
- Birth Control Effectiveness: Birth control methods, such as pills, implants, and IUDs, primarily work by preventing ovulation or altering the cervical mucus to hinder sperm movement.
- Variations in Ovulation: A woman's ovulation cycle can vary, making it challenging to predict the exact "safe" days for unprotected sex.
- Importance of Consistent Use: The effectiveness of birth control heavily relies on consistent and correct use.
Even with birth control, there's a chance of pregnancy if:
- The birth control method is not used correctly or consistently.
- Ovulation occurs despite the birth control method.
Therefore, even while on birth control, the potential for sperm to survive and possibly fertilize an egg remains for up to 5-7 days.
