How long does sperm survive outside the body?

Many couples do not want to have children before they get married. So they ask men not to get sperm into their bodies. However, sperm often gets into their bodies accidentally. At this time, many women want to know how long sperm can survive outside the body so that they can be prepared. Let me introduce it to you.

Sperm survival time outside the body: Sperm survival time outside the body is generally about 30 minutes, but if you do not ejaculate inside, the chances of pregnancy are low.

Sperm can be divided into animal sperm and plant sperm. Male cells in the process of sexual reproduction of animals, reproductive cells of male animals, male gametes in heterogamous reproduction, and haploid reproductive cells produced by the spermatorrhea. In life, sperm refers more to mature male reproductive cells, which are formed in the testis. Semen is an organic substance. Semen contains fructose and protein, as well as some enzymes, inorganic salts and organic salts.

Five factors

1. Car exhaust

Nowadays, people living in big cities cannot do without masks. Especially for women who are preparing to get pregnant, the sulfur dioxide and carbon dioxide contained in automobile exhaust may not only increase the incidence of diseases such as tumors, but most seriously, the dioxins contained in exhaust are extremely strong environmental endocrine disruptors, which can change the shape of men's testicles, reduce the number of sperm, and reduce spermatogenesis.

2. Tobacco and alcohol

Smoking is harmful to health, especially to semen. Compared with non-smokers, smokers have significantly lower indicators of semen quality, higher sperm deformity rate, and more white blood cells in semen. Alcohol has a direct impact on the human liver and male testicles. Excessive alcohol intake by the liver will cause testicular atrophy, leading to a decrease in semen quality.

3. Noise and radiation

Noise can disrupt the body's endocrine system and cause abnormalities in semen and sperm. Long-term noise pollution can cause male infertility; for women, it can cause miscarriage and fetal malformations. Large doses of radiation can cause changes in testicular tissue structure, increase the rate of sperm deformity, and reduce important indicators such as sperm count and sperm density.

4. Frequency of sexual intercourse

In order to increase the success rate, some prospective parents reduce the frequency of sexual intercourse to improve the quality of sperm. In fact, if a man only ejaculates 1-2 times a month, the number of sperm will increase, but the activity and survival rate of sperm will decrease, and the proportion of aging sperm will increase significantly, which is not conducive to conception. Experts recommend that sexual life should be moderate to 1-2 times a week, and women can increase the frequency appropriately before and after ovulation.

Through the introduction above, you should know that sperm can survive for a relatively long time outside the body. So if you don't want to have children, you should take corresponding preventive measures to reduce the occurrence of problems. At the same time, you should also pay attention to whether the preventive measures are appropriate, so as not to damage your body and lose more than you gain.
