What is male infertility? Why does male infertility occur? Nowadays, more and more men are experiencing infertility
According to the regulations of the World Health Organization, couples who have not taken any contraceptive measures for sexual intercourse for more than 1 year and have caused female infertility due to male factors are considered male infertility.
There are multiple reasons for male infertility, and there are too many cases of unknown causes
According to the diagnosis and treatment guidelines for male infertility, the main causes of decreased male fertility include congenital and acquired urogenital malformations, reproductive tract infections, elevated scrotal temperature (varicocele), endocrine disorders, genetic defects, and immune factors.
It may seem obvious at a glance, but when it comes to a patient, what exactly causes infertility is often a difficult question to answer.
It's difficult to explain clearly, "the expert also felt helpless," because male infertility has a characteristic of too many unexplained cases
The so-called unexplained infertility, also known as idiopathic infertility, refers to the situation where both husband and wife use existing examination methods without obvious abnormalities, but have not conceived a child; Alternatively, if the examination simply indicates that the quality of male semen is not good, and semen analysis shows oligozoospermia, asthenozoospermia, and malformation, but the cause is unknown, it is called "idiopathic semen abnormality".
Among the causes of male infertility, this unexplained or idiopathic semen abnormality accounts for the largest proportion, reaching 60-75%. And varicocele only accounts for 12.3%, urinary and reproductive tract infections are only 6.6%, and other factors are even less
Although there are many reasons for infertility, they are basically reflected in semen, regardless of whether it is good or bad. Therefore, semen analysis is the most routine examination.
Can semen analysis determine the "life and death" of infertility?
What is the weight of a semen test result?
A semen test case is in a male clinic. A patient placed a semen report on the table, and the expert looked at it and said, "This test result shows poor semen quality
Upon hearing this, the patient immediately became nervous and said, "What should I do? Am I unable to give birth? Do I need treatment? Can I be treated
Semen assay analysis
Dynamic changes in male sperm
In fact, just one abnormal semen report does not necessarily indicate any problem, and a re examination is necessary, "the doctor told the patient. Because the growth cycle of sperm is generally 3 months, during which there are dynamic changes that may vary from day to day.
The World Health Organization once conducted a survey in which researchers conducted bi weekly semen tests on some men who had already given birth. The results showed that the highest sperm count was over 100 million. However, if some patients were in a cold or fatigue state during the examination, the sperm count could suddenly drop to over 2 million.
Semen examination estimates infertility with only 70% accuracy
Therefore, using semen examination to estimate infertility is only 70% accurate! "The expert further explained," Even if the semen examination is abnormal, it cannot be said to be infertility. It can only be said that the quality of semen is poor, but there is still a possibility of fertility
Moreover, even if all tests (including semen tests) are normal, the factor of male infertility cannot be ruled out, which belongs to idiopathic infertility as mentioned earlier.
In fact, the true value of semen analysis lies only in facilitating doctors to distinguish between three states: low fertility, uncertain fertility, and good fertility.
Semen test cannot be the only diagnostic indicator for infertility
If the patient is diagnosed with oligozoospermia (total sperm count less than 20 million per milliliter), weak sperm (sperm motility<50%), or abnormal sperm disease (normal sperm morphology<14%), then fertility may be low, but it may not necessarily lead to infertility.
In other words, none of the semen tests can serve as a diagnostic indicator for infertility, but rather as a reference for understanding the possibility of infertility.
Of course, if the male partner has severe oligozoospermia, even azoospermia, or severe asthenozoospermia, dysspermia, etc., the responsibility for infertility is difficult to shirk.
