Is 4-day-old sperm capable of pregnancy?

The quality of male sperm has always been a topic of great concern to everyone. During sexual intercourse, if the male's sperm motility is poor, it seems that it is very difficult for women to get pregnant. Under normal circumstances, after male ejaculation, the fertilization ability of male sperm can only reach about 3 days at most. And it will continue to weaken over time, and finally completely lose the fertilization ability.

The first thing newlyweds do is to "make a baby", but insufficient sperm activity of male friends can easily affect fertility. Therefore, you must pay more attention to maintaining your body in your daily life, only in this way can the quality of sperm be up to standard. Under normal circumstances, after a man's sperm is ejaculated out of the body and enters the woman's vagina, it can survive for up to 72 hours. But within 72 hours, the fertilization ability will gradually weaken. The fertilization ability of male sperm is strongest within 24 hours, but if it exceeds 24 hours, the ability will become worse and worse.

Does 4-day-old male sperm have the ability to conceive?

Sperm survival time and sperm fertility time are two different things.

After a man ejaculates, sperm rapidly rises through the vagina to reach the uterus, but poor quality sperm moves slowly and cannot reach the uterine cavity quickly, thus losing its potency. The sperm density that can reach the uterine cavity is only 1% to 5% of that in male ejaculation.

Then when the sperm entered the fertilization site in the fallopian tubes on both sides, it disappeared in a flash, but at this time it had a strong fertilization ability. In the end, only 1 to 2 sperm were lucky enough to fuse with the egg cells, and the other sperm died one after another within 24 to 36 hours.

Sperm survival time can be between 3 and 7 days, but its ability to conceive does not exceed 48 hours, so the probability of pregnancy during ovulation is much greater.

The fertilization ability of male sperm is closely related to the specificity of male sperm. If the motility of sperm ejaculated by a man is very low, even if it can survive in the female vagina for 72 hours, it is impossible to make the woman pregnant. Simply put, male sperm with poor charm cannot meet with the egg cell to produce sperm and egg fusion. Therefore, although the fertilization ability of male sperm can last up to 72 hours, the strongest fertilization period is within 24 hours. If a couple wants to successfully conceive, they must have sex during the woman's ovulation period. Only in this way can the woman have a chance to successfully conceive.

If the quality of a man's sperm is poor, in other words, the sperm motility is very weak, the possibility of making a woman pregnant after 48 hours is generally very small. From a physiological point of view, after a man ejaculates from orgasm, the fertilization ability of the male sperm gradually weakens. Under normal circumstances, the fertilization ability of male sperm can generally last for about 3 days. But if you want to really achieve the goal of pregnancy, the fertility ability of male sperm is the strongest one or two days before. Male friends must pay more attention to physical examinations on a regular basis, and if the sperm survival rate is low, they should actively seek treatment.

In general, I believe that many male friends already know that the fertilization ability of male sperm can only be maintained for about three days at most. If you are anxious to have a baby, the couple should have sex during the woman's ovulation period. Only in this way can the probability of pregnancy be increased, but whether it can make women pregnant is unknown. In the process of having a baby, the couple should actively exercise, and usually eat more foods rich in protein, vitamins and nutrients. Only in this way can women get pregnant as soon as possible.
