Patient's question:
Hello doctor, how is the so-called safe period calculated?Doctor's answer:
Hello! The ovulation date of a woman is generally about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive for 1 to 2 days in the fallopian tube, waiting for fertilization; male sperm can maintain its vitality in a woman's reproductive tract for 2 to 3 days, so sexual intercourse during the days before and after ovulation increases the likelihood of conception. For safety, we refer to the 5 days before the ovulation date, the 4 days after it, and the ovulation date itself as a total of 10 days, known as the ovulation period. Because sexual intercourse during the ovulation period increases the likelihood of conception, it is also called the fertile period or the risky period.
