Sperm can survive inside a woman's body for up to five days.
Sperm Viability and Survival Time
The lifespan of sperm within the female reproductive tract is a crucial factor in determining the window of fertility. Several factors influence how long sperm remain viable, including the quality of the sperm itself and the conditions within the woman's reproductive system.
While sperm are not designed to live for an extended period outside of the body, the female reproductive tract provides a relatively hospitable environment that allows for sperm survival. This allows for fertilization to occur even if intercourse doesn't coincide perfectly with ovulation.
- Optimal Conditions: The cervical mucus and the environment of the fallopian tubes can help protect and nourish sperm, prolonging their lifespan.
- Individual Variation: The exact survival time can vary depending on individual factors.
- Maximum Survival Time: As noted, viable sperm, capable of fertilization, can remain active within the female reproductive tract for up to five days.
The statement "Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days" provides a definitive answer regarding the maximum timeframe.
