What is the Best Time for Having Sex to Increase the Likelihood of Pregnancy?

Women are more likely to conceive during ovulation in the afternoon from 5 to 7 pm in March to April or September to October, which is also considered as the ideal time for pregnancy.

According to scientific research on the likelihood of conception throughout the day, if planning for pregnancy, the optimal time for sexual intercourse is in the afternoon from 5 to 7 pm. Studies have found that both the quantity and quality of sperm vary greatly throughout the day, reaching a peak in the late afternoon, coinciding with the time when women are most fertile.

Women's ovulation generally occurs around 14 days before the next menstrual cycle. After ovulation, the egg can survive for 1-2 days in the fallopian tube, waiting for fertilization. Male sperm can maintain fertility for 2-3 days in the female reproductive tract. Therefore, sexual intercourse during the few days before and after ovulation is more likely to lead to pregnancy. To be on the safe side, the five days before and four days after ovulation, including the ovulation day itself, are collectively referred to as the fertile period, which spans a total of 10 days. Sexual intercourse during this period is more likely to result in pregnancy, hence the fertile period is also known as the susceptible or critical period.

The ideal seasons for conception are late spring or early autumn, specifically March to April or September to October. Scientific advice suggests that conception during the late summer and early autumn is preferable. This is because the early pregnancy symptoms would occur during autumn, avoiding the impact of summer heat on appetite. Additionally, the availability of fresh vegetables and fruits is abundant during this time, making it easier to increase nutrition and regulate appetite. When winter, a season prone to windpox and influenza, arrives, the pregnancy would have reached the mid-term, reducing the impact on the development of fetal organs. Full-term delivery would occur during the pleasant spring-summer transition, beneficial for the newborn to adapt to the external environment and facilitate good growth and development.
