Patient's question:
NoDoctor's answer:
Generally, the five days before ovulation and the four days after ovulation are collectively referred to as the fertile window. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days, waiting for fertilization; male sperm can remain in a woman's reproductive tract for 2-3 days, maintaining the ability to fertilize. Therefore, sexual intercourse during the days before and after egg release increases the likelihood of conception. For safety, we refer to the five days before the day of ovulation, the four days after, and the day of ovulation itself as a total of 10 days—the fertile window. Because sexual intercourse during the fertile window increases the likelihood of conception, this period is also known as the "high-risk period" or "dangerous period."
