Patient's question:
NoDoctor's answer:
Hello, the ovulation period is approximately 14 days before the next menstrual period. On this day, an egg is released. The egg can survive for 1 to 2 days, while sperm can survive in the uterus for 2 to 3 days, losing the ability to combine with the egg after this period. Therefore, we refer to the 5 days before and 4 days after the ovulation day as the fertile window, during which sexual intercourse increases the likelihood of pregnancy.
