At present, there are a variety of departments that deal with male infertility, such as: sexual medicine, gynecology, urology, endocrinology and so on. Although there is some overlap between them, they are still significantly different from each other. For example: Sexual Medicine Department: focuses on helping patients with sexual rehabilitation. If your infertility problem is mainly due to sexual dysfunction (bad erection, non-ejaculation, retrograde ejaculation, etc.), and you choose the Sexual Medicine Department to help you overcome your sexual dysfunction, then your fertility problem may be a matter of course. Endocrinology: endocrine diseases can also cause male infertility, for example, hyperprolactinemia patients, through the endocrinology department to reduce the level of prolactin, 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 ejaculatory duct obstruction and infertility may be able to restore the patency of the spermatic duct through transurethral electrolysis. Men’s Surgery: In fact, diseases or abnormalities surrounding fertility may involve a multitude of departments, all of which should first be examined and diagnosed in Men’s Surgery, where the vast majority of the problems mentioned above can also be resolved. In summary, the best choice for male infertility patients is the male department. Different hospitals have slightly different departmental settings, for example, the best recognized unit for male reproduction in China is the Male Clinic of the Center for Reproductive Medicine of the Third Hospital of Peking University, while inpatients are admitted to the Reproductive Center and Urology Ward respectively. The number of outpatient visits, the proportion of difficult cases, and the quality and quantity of male reproductive surgeries are among the highest in China and even in the world. Recently, the male reproductive microsurgery training base of the Chinese Medical Association Men’s Branch will also be located here to train male reproductive microsurgery talents for China.
