Yoram Yasur Abt | Male infertility is defined as the inability of a man to impregnate a fertile woman. After trying for a long time and without any method of contraception.
In people under 30, between 20 and 37% achieve pregnancy in approximately 3 months.
But when there are medical conditions that interfere with the ability to conceive.
When we start talking about infertility. According to several studies, 15% of couples trying to conceive.
For a year without success are infertile.
Yoram Yasur Abt: “As the biological process of reproduction is more focused on the woman, who hosts the future baby inside her body, we tend to believe that when a couple is unable to conceive infertility is in the woman. However, 7% of all men are infertile and among infertile people, between 40 and 50% are men”.
The importance of semen and spermatozoa:
Fertility in men depends on the quality of the semen, the organic fluid through which sperm move, which are the haploid cells (male gamete) that fuse their nucleus with an ovum of a female (gamete), which later will lead to the formation of an embryo and fetus.
For this reason, semen is very important in sexual reproduction. The quality of the semen is measured by the ability to achieve fertilization, that is, what define the semen quality are the spermatozoa, both in quantity and in their functional capacity. A “good quality” sperm is one that can travel to the position of the eggs to fuse their nucleus.
The road to fertilization:
In order for men to be clinically capable of conceiving, several things must happen. On one hand, man must produce healthy spermatozoa.
They have an adequate quantity and quality. As sperm are produced in the testicles. This requires the proper functioning of the male reproductive organs.
Which depend mainly on proper formation and growth during puberty. In turn, the body of man must produce the necessary amount of testosterone. And other hormones that are involved in the production of sperm.
Once formed, the spermatozoa must be transported to the semen. This is done through specific tubes that lead to the sperm.
In the semen and then be ejaculated by the penis.
In this case, a correct amount of spermatozoa is necessary in the semen.
Since the smaller the amount, the less chance a sperm can fertilize an egg.
A low concentration of spermatozoa is about 15 million sperm per milliliter of semen or less than 39 million per ejaculate.
“In addition, spermatozoa have to be able to be functional and able to move. In case the movement or functionality is not appropriate. Then it is likely that they will not find the egg or not penetrate it.”
