Although the examination of male infertility is different from that of female infertility, the basic methods of asking medical history, physical examination and general laboratory examination are the same. Male infertility is mostly due to low semen quality, so routine semen testing is a necessary examination for every patient. For problems found in routine semen tests, some require further investigation of their causes.
For those suspected of having obstruction of the vas deferens, a vas deferens angiography is required to understand whether there is obstruction, the extent and location of the obstruction. In addition, chromosome examination is required for patients with sexual dysplasia or multiple miscarriages of their wives. To determine the root cause of testicular dysfunction, blood hormone testing is also necessary to determine whether the lesion is in the testicles themselves, or in the hypothalamus or pituitary gland.
To determine the function of the epididymis, prostate, and seminal vesicles, a series of biochemical tests should be conducted to select representative chemical components of each organ. For example, fructose can be measured for seminal vesicles, citric acid and acid phosphatase can be measured for prostate problems, and carnitine and glycerophosphate choline can be measured for epididymis problems. For patients whose semen quality is normal and the female partner is basically normal, immunological tests should be conducted to understand whether there is any occurrence of self anti sperm antibodies. Finally, if all the tests are normal and still cannot make the woman pregnant, it is necessary to consider whether there is a problem with the function of the sperm.
