A man's marriage is first a manifestation of being responsible for their partner, and second is the responsibility of bearing children. Although many couples choose not to have children, the first thing most couples do after marriage is to have children. However, the path of having children can be extremely difficult, as some men may suffer from infertility. The following four symptoms indicate male infertility.
1. Poor sperm quality
Excessive number of inactive or dead sperm (over 20%) in semen, poor sperm motility, or deformed sperm exceeding 30% can often cause infertility.
2. Absence or oligozoospermia
When the sperm density in semen is less than 20 million/ml, the chances of a woman becoming pregnant are reduced, and when it is less than 20 million/ml, it leads to infertility. This type of infertility can be divided into permanent and temporary, with the former occurring in patients with congenital testicular developmental disorders or severe testicular and seminal vesicle lesions; The latter is more common in cases where excessive sexual activity leads to a one-time failure of spermatogenic function, usually resulting in reduced sperm count rather than complete azoospermia.
3. Abnormal physical and chemical properties of semen
After ejaculation, normal semen quickly solidifies into a gel like state, and then liquefies completely within the next 15-30 minutes. If semen does not solidify after ejaculation, or if liquefaction is incomplete, it often indicates lesions in the seminal vesicle or prostate gland. Bacterial and viral infections of the reproductive tract can also cause changes in semen composition, leading to infertility. More than 103 pathogenic bacteria/ml in semen and more than 104 non pathogenic bacteria/ml can cause infertility.
4. Diseases of the testicles themselves
Such as testicular tumors, testicular tuberculosis, testicular syphilis, non-specific inflammation of the testicles, testicular atrophy after trauma or torsion of the spermatic cord, and testicular absence, can all cause spermatogenic dysfunction and infertility.
In addition to the above symptoms, there is another symptom that also means that men cannot conceive, which is chromosomal abnormality. Because chromosomal abnormalities can hinder the development of the male reproductive system, possibly due to testicular or penile deformities, sperm cannot bind to the egg. Such a man can marry but cannot have children.
