Lifespan of sperm
5 amazing things to know about SPERMTOZOIDS
***The lifespan of a sperm is 30 days
If there is no ejaculation, the sperm live for about 30 days in the male body before being destroyed and replaced.
When there has been ejaculation and the sperm then move through the female body, their lifespan is 2 to 5 days. This is why having sex a few days before ovulation can lead to pregnancy.
***Semen contains an average of 100 million sperm per milliliter
Semen is 20% sperm and 80% fluid, produced by the seminal vesicles and the prostate.
The ejaculated volume is on average 3 to 4 milliliters and contains about 100 million sperm per milliliter.
The number of sperm in the semen is also one of the basic measures of male fertility.
***Spermatozoa prefer winter
The period when the most children are born is from July to October, with a peak in September, these children are therefore conceived in winter.
Is it because we have more sex in the winter?
No, say researchers at the Soroka University Medical Center in Israel.
Indeed, these researchers discovered that male reproductive cells prefer the winter season.
By examining nearly 6,500 sperm samples from men who had consulted the department of assisted reproduction with their partner, they realized that in winter, in healthy men, the spermatozoa were more numerous, better trained and above all more mobile!
***It takes 70 days to produce sperm
The process of producing sperm is called spermatogenesis and it lasts a little over 70 days.
Spermatogenesis takes place in several stages. First with stem germ cells, the spermatogonia.
These multiply and turn into spermatocytes, then spermatids and finally spermatozoa.
At each stage, they will migrate and acquire new components.
Spermatogenesis begins in the seminiferous tubules of the testicles, where the temperature is lowest (34°C), because at body temperature the formation of spermatogonia would be impossible.
They then pass into the epididymis, a small canal overhanging the testicle in which they gain their flagella, which allow them to move.
Finally, they migrate to the seminal vesicles where they mix with the liquid that will be propelled at the time of ejaculation.
***Sport increases the concentration of sperm in sperm
A study conducted has shown the link between physical activity and criteria for good male sex cell health.
According to this study, conducted on 189 men aged 18 to 22, the regular practice of 7 hours of sport per week increases the concentration of sperm in spermatozoa by nearly 50% compared to a weekly practice of less than one hour.
The results also showed that from more than 15 hours of physical activity per week, the concentration of sperm in sperm increased 73% higher than those who exercised less than five hours.
According to these researchers, the most profitable sports would be weightlifting and outdoor activities.
