Pregnant couples who are preparing for in vitro fertilization are required by doctors to abstain for a few days before getting pregnant. The main purpose of abstinence is to improve the quality of the sperm and eggs of the couple, facilitate conception and eugenics. So how long does the man need to abstain before undergoing in vitro fertilization in response to abstinence? Please take a look together with the editor.

Generally speaking, ordinary people do not need to abstain before preparing to conceive. Normal men can fulfill their reproductive needs as long as their sperm quality is not compromised. If you want to increase the chances of pregnancy, you can moderate abstinence for about 5-7 days. It is worth noting that the longer the abstinence time, the better. If semen is stored in the seminal vesicles for too long, it can cause sperm aging, loss of vitality, and reduce the chance of pregnancy. Therefore, there is no need for special abstinence before preparing for pregnancy. If the pregnancy period is too long, the quality and quantity of each sperm will be affected, thereby reducing the chances of a woman becoming pregnant.

Generally speaking, the best time to conceive is the day before ovulation or the day of ovulation. If you don't know how to calculate ovulation day, you can start from the first day of menstruation, and around the 14th day is ovulation day. Monitor the basal body temperature, and if it rises, it can be determined as ovulation. In general, women can survive for 2 days during ovulation, while sperm entering the female reproductive tract can last for 1-3 days. This time difference can be used to have sexual intercourse 1-3 days before ovulation, on the day of ovulation, or 1-2 days after ovulation, which can increase the chances of pregnancy.

When the body is healthy and the reproductive system is working normally, abstinence for 3 to 7 days can replenish semen. However, prolonged abstinence can actually lead to decreased sperm quality and death. The husband and wife are preparing to conceive, and only need to abstain for 3-5 days to achieve the best sperm quality. In addition, it is necessary to control the time of pregnancy, prohibit smoking and alcohol consumption, eat light food in daily life, and avoid spicy and stimulating food to avoid affecting sperm treatment. To ensure sufficient sleep and not overwork, it will increase the chances of pregnancy.
