If azoospermia is diagnosed, it is necessary to check which type of azoospermia it belongs to. There are two types of azoospermia: the first one is obstructive azoospermia, which means that the epididymis, vas deferens and ejaculatory ducts are not smooth, and sperms can not be discharged. This kind of patients have spermatogenic function of the testes, and if they want to procreate, they can be restored through the epididymal vasovasal anastomosis under the microscope, or vas deferens vasovasal anastomosis under the microscope, or the spermatoglyphic endoscopic surgery, and some of the patients can discharging sperms to procreate their own offspring. The second type of patients belongs to non-obstructive azoospermia, that is, the tube for sperm discharge is open, but the testes have problems with sperm production. Most patients who want to have offspring can obtain a small amount of sperm through microsperm extraction, and about 40% of patients can obtain a small amount of sperm to have offspring. If these are not a solution, the offspring will be adopted or sperm from a sperm bank will be used to produce offspring.
