What do the researchers inform about men's reproduction trends?
The researchers found that the number of sperm in a man is decreasing since year 1950. In this 50 years ago, they found that the number of sperm in a man is in lower rates by 50%.
What are differences between normally sperm and abnormally sperm?
Number of Sperm:
Usually when sperms were produced from the testicles, they will be sent to the bulb which is called "seminal vessicle" within the abdomen. When the male reached the orgasms, then sperms will be injected to mix with the eggs of the female. As a matter of fact, the human's reproductive system has a very low efficiency. Because each time the male ejaculates the semen into female's vagina, there're about 40 to 120 million sperms, but there is only one sperm that it can mix with eggs. So by this ratio, if some male has sperms than 20 million in each ejaculation, then it's likely to get trouble if they want to have a child.
When does sperm get mixed with eggs and make female get pregnant?
Ovulation:
In addition, the sperms will be mixed with the eggs only if it's the same time that the female get ovulation. The best chance is having intercourse in the same day with ovulation. the minor chance is having sex on the day before the ovulation day. But the day after the ovulation will get most bad result of getting pregnancy. So generally people will don't know which day is the ovulation day, but if they've often got sexual intercourse, they'll get more chance that the female get pregnant. Sometimes, it seems that it's a coincidence of getting pregnancy.What is the furthermore information that the researcher got from the ratio of fertile and Infertile men?
Testicular Cancer:
The research hasn't only found a decrease of the number of sperm. But it has also found that the quality of sperm are diminished as well. Actually, the good sperm must be strong and movable. But this is not so in the latter generation of men. Furthermore, it also found that men have more issues about the increasing rate of testicular cancer and that the testis doesn't get into the scrotum. Moreover, the size of testis is smaller as well. All this is the reason why the male are diminished to reproduce. There are other factors that maybe they affect to the weak of the sperm. Let's see more below..Why do men get hard to reproduce?
- Men today decide to have a desire of getting a child at the age more that 33.
That is why the number of sperm get decreased by nature.
- Men today have sexual freedom than before.
It affects an infection such as infertility as well.
- Men today wear bikini underwear.
It affects getting humidity in the surrounding area. Because the air can't flow in and out, the result is that the semen got weak and the sperm production is diminished.
- Taking a hot bath of sauna is also one of the reasons to decrease the number of sperm production of testicles.
Because of the environmental pollutants, such as DDT, dioxins ,some PCBs and synthetic variety. these things are very likely to affect the fertility of the reproductive ability of men. Because when these toxins go into the body, they will affect a distorted work of sexual hormones.
