Azoospermia is usually referred to as azoospermia, and the treatment of azoospermia includes medication and surgery. Azoospermia is diagnosed when no sperms are found in the semen after centrifugation for 3 or more times, and the causes such as ejaculation and retrograde ejaculation are excluded. It can be divided into three categories: obstructive azoospermia, non-obstructive azoospermia, and mixed azoospermia, and the treatments are not the same. 1. Obstructive azoospermia: azoospermia is usually caused by obstruction of the epididymis or the vas deferens, and can be treated by epididymal-vas deferens anastomosis, etc. The cause of azoospermia is the obstruction of the epididymis and the vas deferens. 2. Non-obstructive azoospermia: patients can use spermatogenic capsules, spermatogenic tablets and other drugs to treat, conservative treatment is ineffective can be performed testicular sperm extraction and other assisted reproductive technology. 3. Mixed azoospermia: there is obstruction of the vas deferens and low spermatogenic function of the testes. It can be treated by epididymo-vasectomy and medication, as well as assisted reproduction techniques such as testicular sperm retrieval. Azoospermia must be treated in relevant hospitals to avoid adverse effects.
