Patient's question:
Please ask if ovulation occurs in the morning or at night, and how long can the egg cells survive?Doctor's answer:
Hello, the ovulation date for women is generally about 14 days before the next menstrual period. For safety, we refer to the 5 days before the ovulation day, the 4 days after, and the ovulation day itself as a total of 10 days, known as the fertile window. Generally, an egg can survive for 1 to 2 days after being released, and sperm can survive in the female reproductive tract for 2 to 3 days. The fertilization ability of sperm is usually at its peak within 24 hours after ovulation, and sperm loses the ability to combine with an egg after 2 to 3 days.
