2. Semen test: This is the most important and necessary male infertility test to judge male fertility. This male infertility test is sometimes repeated many times.
3. Immunological examination: Some infertility is related to the existence of sperm antibodies (sperm agglutination antibodies, etc.). ) in the body, so the male infertility test sometimes needs related immunological tests.
4. Examination of endocrine function: The development and differentiation of spermatogenic cells depend on the coordination of the whole endocrine system. Through endocrine examination, we can know whether the endocrine function of the body, especially the function of hypothalamus-pituitary-testis axis, which is most closely related to spermatogenesis, is normal. If it is abnormal, it is necessary to find out which link has gone wrong, so as to clarify the cause of infertility and provide targeted treatment.
5. Chromosome examination: With the development of genetics, it is found that some infertility (especially habitual abortion) is caused by chromosomal abnormalities of both husband and wife. These abnormalities can be manifested as the increase or decrease of chromosome number or structural abnormalities (such as chromosome breakage, deletion and translocation, etc.). Therefore, chromosome examination is necessary when some patients are examined for male infertility.
6. X-ray examination of vas deferens: epididymal radiography, vas deferens seminal vesicle radiography and urethrography can be performed according to the situation. This male infertility examination project is mainly used for patients with suspected vas deferens obstruction to determine whether the vas deferens is abnormal, deformed, unobstructed and obstructed.
7. Testicular biopsy: The male infertility examination project can mainly understand the fine structure of testis, whether the spermatogenic condition of spermatogenic epithelium is abnormal, whether the development of interstitial cells is normal and so on. It has been widely used in the diagnosis of male infertility. In addition, testicular biopsy can also be used for the diagnosis of testicular tumors.
8. Doppler ultrasound examination: This male infertility examination project is mainly used for patients who are suspected of having varicocele (especially occult varicocele) but are difficult to find and confirm through general examination and palpation.
9. In vitro sperm penetration test: Male infertility test also includes in vitro sperm penetration test.
