Patient's question:
NoDoctor's answer:
It is best to have intercourse during ovulation, as the chances of pregnancy are higher. Ovulation is influenced by the cyclical changes in endocrine hormones secreted by the pituitary gland and ovaries. Both have the same cycle length, which is one cycle per month, and ovulation occurs between two menstrual periods. The calculation method is to start from the first day of the next menstrual period, count backward 14 days or subtract 14 days to determine the ovulation day. The days before and after the ovulation day, plus the ovulation day itself (5 days before and 4 days after), are collectively referred to as the fertile window.
