Currently, there are various departments that treat male infertility, such as sexual medicine, gynecology, urology, and endocrinology. Although there is some overlap between them, they are significantly different from each other. If your problem of infertility is mainly due to sexual dysfunction (bad erection, non-ejaculation, retrograde ejaculation, etc.), if you choose sexual medicine to help you overcome the sexual dysfunction, the fertility problem may be a matter of water under the bridge. Endocrinology: Endocrine diseases can also cause male infertility, for example, in patients with hyperprolactinemia, through the endocrinology department to regulate and reduce the level of prolactin, you can improve the quality of semen, fertility will no longer be a problem. Urology: Focuses on the rehabilitation of certain diseases of the reproductive organs, for example, patients with infertility of ejaculatory duct obstruction may be able to restore the patency of the seminal tract through transurethral electrodesiccation. Male medicine: In fact, there are numerous departments that may be involved in diseases or abnormalities surrounding fertility, and all of these problems should be examined and diagnosed first in male medicine, where the majority of the problems mentioned above can also be addressed. In conclusion, the best choice for male infertility patients is male medicine. For example, the best unit for male reproduction in China is the Male Specialized Clinic of the Center for Reproductive Medicine at Peking University Third Hospital, while inpatients are in the Reproductive Center and the Urology Ward. The quality and quantity of male reproductive surgery here is far ahead in China and even in the world, regardless of the number of outpatient visits, the proportion of difficult cases and the quality and quantity of male reproductive surgery. Recently, the male reproductive microsurgery training base of the Chinese Medical Association Male Branch will also be located here to train male reproductive microsurgery talents for China.
