Patient's question:
How many days can ovulation last in a month?Doctor's answer:
Women of normal childbearing age release only one egg from the ovary each month. It takes about 14 days for a primordial follicle to develop into a mature follicle and ovulate, during which a series of complex physiological and biochemical reactions occur. During this process, special cells in the follicle secrete male and female hormones. Female hormones regulate the cyclical changes of the endometrium, forming the menstrual cycle.An egg can survive for 1-2 days after being released, while sperm can survive in the female reproductive tract for 2-3 days. Fertilization capability is usually within 24 hours after ovulation, and sperm loses the ability to fertilize an egg after 2-3 days. Therefore, having intercourse 2-3 days before and 1-2 days after ovulation increases the chances of conception, and this period is called the fertile window or risky period.
A woman's ovulation date is generally about 14 days before her next menstrual period. For safety, we consider the 5 days before and 4 days after the ovulation day, including the ovulation day itself, as a total of 10 days, which is called the ovulation period. The remaining time, except for the menstrual period, is called the safe period.
