1, check gonadotropin:
The determination of gonadotropin is of great value in judging the functional state of male hypothalamus-pituitary-gonad axis. By observing the value of follicle stimulating hormone, we can know the degree of testicular development or injury. Under normal circumstances, the spermatogenesis of male seminiferous tubules is mainly promoted by follicle stimulating hormone secreted by pituitary gland. Of course, this should be achieved under the condition of normal testosterone, because there is insufficient testosterone in the blood, even if the follicle-stimulating hormone secreted by the pituitary gland is normal, semen will have problems. As far as simple testicular hypoplasia is concerned, the worse the testicular development, the more obvious the spermatogenic disorder and the higher the serum follicle stimulating hormone value. In addition, the detection of luteinizing hormone and prolactin also has very important clinical value.
When the spermatogenic function of testis is impaired, the response of luteinizing hormone is significantly lower than that of follicle stimulating hormone. When the chromosome is abnormal and testicular atrophy, luteinizing hormone will be significantly higher than the normal chromosome. For male infertility with high luteinizing hormone, it is suggested to consider whether the chromosome is normal. Elevated prolactin can also lead to male infertility, such as testicular atrophy, decreased sperm count and decreased sperm motility.
2. Do special project inspection:
Antisperm antibody test. People who are positive for anti-sperm antibodies often have other problems at the same time, some of which are closely related to this positive. For patients with poor sperm quality, low sperm count and high sperm abnormality rate, although the possibility of chromosome abnormality is ruled out, anti-sperm antibody should be checked, because anti-sperm antibody positive itself can completely lead to this, and anti-sperm antibody positive may be accompanied by other problems. For example, about 70% of anti-sperm antibody positive people are infected with Ureaplasma urealyticum at the same time, which is one of the important causes of infertility. The clinical study of Chongqing Union Medical College Hospital found that the content of anti-sperm antibody in semen had an obvious upward trend in some cases with positive pathogenic microorganisms including Ureaplasma urealyticum.
Anti-sperm antibody and Ureaplasma urealyticum are both "enemies" of sperm quality. The positive rate of anti-sperm antibody in patients infected with Ureaplasma urealyticum is much higher than that in normal uninfected patients, which indicates that male Ureaplasma urealyticum infection is the inducement to produce anti-sperm antibody. If the anti-sperm antibody is positive, the patient should be further examined for Ureaplasma urealyticum. If it is positive, it should be treated at the same time.
The above is the common test method for male infertility that we prepared for you today. To learn more, you need to search and find it yourself. Conditional friends can also consult professional doctors one-on-one. I suggest you pay more attention to your health in your daily life, stay away from alcohol and tobacco, don't overeat, and go to the hospital in time when you encounter problems.
