Patient's question:
On the 20th of last month, my period started, and it ended on the 25th. Could you please tell me on which day my ovulation period is? How is it calculated?Doctor's answer:
Hello, the ovulation day is generally around 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. After this period, sperm lose the ability to fertilize the egg. 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 chances of pregnancy.
