Final answer:
Sperm can live up to 5 days in a woman's body, but the highest chances of pregnancy occur within the first 1 to 2 days after intercourse.
Step-by-step explanation:
Sperm can live inside a woman's body for up to 5 days.
After ejaculation, sperm enters the vagina and travels through the cervix into the uterus. From there, they can reach the fallopian tubes where fertilization of an egg can occur. If an egg is not fertilized, the sperm will eventually die and be expelled from the body.
It's important to note that the chances of conception decrease significantly as the days go by, so the highest chances of pregnancy occur within the first 1 to 2 days after intercourse.
