Infertility<\/span> is defined as the inability to achieve a pregnancy after 12 months of unprotected intercourse. According to a recent <\/span>report<\/span><\/a> published by the World Health Organization (WHO), many people experience infertility at some point in their lives. In fact, about 17.5% of adults (that is, about one in six) have this problem. This is why it is urgent to increase access to information and attention to infertility, accessibly and qualitatively, for those who need it.<\/span><\/p>\n

The male <\/span>contribution<\/span><\/a> to the infertility of the couple ranges between 30 and 40% of the cases. One in 20 males generally has some type of fertility problem, with low sperm counts in the ejaculate. However, only one in 100 men does not have sperm in his ejaculate. What are the main causes of this? How many have a solution? What to do to avoid it? We will be talking about these issues in the article.<\/span><\/p>\n

Life of a sperm<\/b><\/p>\n

Before fully talking about the subject of male infertility, we must refer to <\/span>spermatogenesis<\/span><\/a>. Or, to put it simply, to the process of formation of the spermatozoa, which are the male <\/span>gametes<\/span><\/a>. This process occurs in the testicles, specifically in a structure called the testicular seminiferous tubules, and lasts approximately 62 to 75 days.<\/span><\/p>\n

However, the formation of spermatozoa begins, strictly speaking, much earlier: around day 24 of the embryonic development of the male organism. At that time about 100 germinal cells are produced that migrate towards the buds of the genital organs. About the fourth week of development, they will have become about 4,000.<\/span><\/p>\n

But it is not until puberty that the testicles begin to produce sperm. This process will continue throughout the life of the man, although the quality and quantity of the spermatozoa may decrease over time.<\/span><\/p>\n

On the other hand, it is essential to understand that this is a hormonally controlled process. It involves the <\/span>hypothalamic-pituitary-gonadal axis<\/span><\/a>. Alterations in the secretion of hormones can lead to non-generation of spermatozoa.<\/span><\/p>\n

Phases of spermatogenesis<\/b><\/p>\n

Spermatogenesis <\/span>consists<\/span><\/a> of three phases. In the first, first-level germinal cells are formed from a stem cell, which have a complete set of chromosomes. That is 23 pairs.<\/span><\/p>\n

In the second phase, the genetic information is halved. In this way, the initial spermatocyte, with 46 chromosomes, divides into two second-level spermatocytes that, in turn, divide into two cells with 23 chromosomes.<\/span><\/p>\n

The final maturation of the cells occurs in the third phase. During the process, the tail increases in size and the head, which contains the genetic information, decreases and becomes pointed in order to pass through the area that precedes the ovule.<\/span><\/p>\n

The hormones involved in sperm formation are:<\/span><\/p>\n
