Key takeaways:

  • Sperm can live in the female reproductive system for as long as five days, depending on the environment

  • Sperm are continually produced in the testes, meaning most men are fertile throughout their lifetime 

  • Sperm quality is an important factor in fertility and can be promoted by making healthy lifestyle choices

Sperm can live inside a woman's body for up to five days. If you have unprotected sex even a few days before you ovulate, there's a chance of getting pregnant. In this article, we’re tackling the life cycle of sperm, plus their survival rate in different circumstances. Read on to learn more about what can influence sperm production, survival, and health.
