How long does sperm survive in the fallopian tube?

Nowadays, many doctors and experts have done a lot of research on sperm and eggs, because the fertilized egg period is a relatively important period and is the key to fetal development. And now women do not have a correct understanding of their own physical conditions. So, today we will introduce to you how long sperm can survive in the fallopian tube, and whether the sperm survival rate is high? Let's take a look together.

A man's sperm can only live for 24 hours outside the body.

Although a normal sexually mature man can discharge tens of millions or even up to 200 million sperms in one ejaculation, most of these sperms lose their vitality and die in the acidic environment of the female reproductive tract. Generally speaking, the life span of sperm in the vagina does not exceed 8 hours, and only a small number of sperms escape and continue to move forward. When sperms rush up to the uterine cavity, their number is only 1%-5% of that at ejaculation. Why is this? Because the sperms that remain in the semen during ejaculation can be protected by a large amount of fructose and enzymes that decompose sugars in the semen. When the sperms enter the uterine cavity, they leave the semen and their living conditions are far worse than in the semen, so their life span is greatly shortened. Poor-quality sperms move slowly and cannot quickly reach the uterine cavity, and they lose their vitality. After passing through so many checkpoints, only a few sperm can finally reach the fertilization site in the fallopian tube.

However, once the sperm enters the fallopian tube, it has a strong fertilization ability. Of course, only 1-2 sperms are lucky enough to combine with the egg, and the rest of the sperms die within 24-36 hours. Only the sperm stored in the crypts of the cervical mucosa can live for 2-6 days, but even so, its fertilization ability has basically been lost, because the fertilization ability of sperm can only be maintained for about 20 hours.

The survival time of sperm and the time of its fertility are two different things. If the living conditions are right, sperm can indeed survive for three to seven days, but its fertility time is no more than about 48 hours. The person above is probably wrong. The egg has the best fertility time between 15 and 18 hours after being released, which is three hours.

The OP's menstrual cycle spans such a large period that the safe period is already very inaccurate. I wonder if you really want to get pregnant or not? If you don't want to get pregnant, then if your cycle this month is 28 days, you may still get pregnant if you happen to have sex on the 18th; if your cycle this month is 34 days, then having sex on the 27th is just as dangerous as above.

If you want to get pregnant, the chances of getting pregnant with this arrangement are very small, because just because you had a follicle stretch at 18, you can't pin all your hopes on this point, which is really too absurd, because in fact, ovulation is not necessarily caused by follicle stretching. In reality, many women have very long follicles, and the ovulation test paper is only weakly positive. It is not the majority of women who can achieve the longest follicle stretch that is consistent with the test paper test result.

The above is what professionals have told us about the survival time of sperm in the fallopian tube. If you are not familiar with this knowledge, you can read more about it in the above article. This will help us have a correct understanding of sperm and make a plan for body care. I hope the above content can help you.
