How to determine the normal number of effective sperm

For couples who are preparing for pregnancy, the most important thing they care about is the calculation method of eggs and sperm. Today we only know one side of it, which is how men calculate their own effective sperm count. I believe that many men do not know this problem. There are many ways to calculate eggs, but nowadays, only the decimal calculation method is rarely mentioned. Let's take a look at it together and understand this issue to provide convenience for couples who are preparing for pregnancy.

1. Normal Rate

The survival rate of normal male sperm should be between 65% and 70%. If it is lower than this value, the sperm survival rate is low. According to your situation, the pregnancy rate is very low, which belongs to weak sperm. There are many reasons for weak sperm. It is recommended to go to a specialist hospital for further examination to clarify the cause so as to provide targeted treatment.

2. Factors that affect sperm quality

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 car exhaust may not only increase the incidence of diseases such as tumors, but most seriously, the dioxins contained in the exhaust are extremely strong environmental endocrine disruptors, which can change the morphology of male testicles, reduce the number of sperm, and reduce spermatogenesis. Tobacco and alcohol: Smoking is harmful to health, especially to semen. Compared with non-smokers, smokers have significantly lower major indicators of semen quality, higher sperm deformity rate, and increased number of white blood cells in semen. Alcohol has a direct impact on the human liver and male testicles. Excessive alcohol intake by the liver can cause testicular atrophy, leading to decreased semen quality. Noise and radiation: Noise can cause endocrine disorders in the human body, leading to abnormalities in semen and sperm. Long-term noise pollution can cause male infertility; for women, it can lead to miscarriage and fetal malformations. Large doses of radiation can cause changes in testicular tissue structure, increase the deformity rate of sperm, and reduce important indicators such as sperm count and sperm density. Frequency of sexual intercourse: In order to increase the hit rate, some prospective parents reduce the number of sexual intercourse to improve sperm quality. In fact, if a man only ejaculates once or twice 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 suggest that sexual intercourse should be moderate to one to two times a week, and women can increase the frequency of sexual intercourse around the ovulation period.

3. Sperm lifespan

Although a normal sexually mature man can release 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 eight hours, and only a small number of sperms escape and continue to move forward. When the sperms rush up to the uterine cavity, their number is only 1% to 5% of that at the time of 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. Therefore, their life span is greatly shortened. Sperms of poor quality move slowly and cannot reach the uterine cavity quickly, so they lose their vitality. After passing through so many checkpoints, only a few sperm can finally reach the fertilization site in the fallopian tube.

IV. Notes

In particular, we should pay attention to zinc supplementation. Animal foods generally contain more zinc than plant foods. Foods rich in zinc include: lean meat, liver, eggs, dairy products, cocoa, lotus seeds, peanuts, sesame seeds, walnuts, seaweed, kelp, shrimp, marine fish, red beans, lychees, chestnuts, melon seeds, almonds, celery, persimmons, etc. It is advisable to eat more semolina, tofu and other soy products, beef, mutton, fish, lean meat, peanuts, sesame seeds, and dairy products.

This is the end of the introduction to your effective sperm count. There are many ways to calculate it, but it is a bit complicated and not suitable for everyone. Different carriers require different calculation methods. You need to choose a calculation method that suits you according to your own situation. In fact, it is similar to the calculation method of female eggs. The ovulation period is different every month and may be advanced or postponed. The same is true for the effective number of male sperm. It is not fixed every day or even every month, and it may be more or less. It depends on factors such as the male's environment, physical condition, and emotions.
