Sperm can survive in the female reproductive system for six days, but they need to have 10 hours after ejaculation to undergo capacitation. Ovulation typically occurs on day 14 of a woman's menstrual cycle. An ovulated egg can survive only up to 24 hours if it is not fertilized. Given this information, what days of a woman's sexual cycle would be a window of opportunity for an egg to be fertilized

Five days prior to ovulation and day of ovulation represents a six day fertile window of a women’s cycle

In the five days prior to ovulation and day of ovulation, the chances of conception are high. These six days represents the fertile window of a women’s cycle during which the sperm with a life span of five days and egg with a life span of 24 hours can fuse. However, likelihood of conceiving increases if two individuals mate in the first three days of these six days fertile window of women’s cycle.
