There are four main types of surgical treatment for male infertility: 1. In order to improve the spermatogenic function of the testes, including high spermatozoal vein ligation, cryptorchidism surgery and testicular transplantation. 2. Surgical procedures are needed to restore the patency of the vas deferens due to obstruction of the vas deferens, and microsurgical techniques can be used to perform vas deferens anastomosis or vas deferens epididymal anastomosis. In case of limited epididymal insufficiency, epididymal duct anastomosis has been used. In cases of limited ejaculatory duct obstruction, urethroscopic dilation or incision of the ejaculatory duct opening may be attempted with occasional success. There is no specific treatment for azoospermia caused by vas deferens. The gamete micro manipulation technique developed in recent years, which extracts sperm directly from the epididymis or testes for intracytoplasmic sperm injection in oocytes obtains successful conception. 3, in order to lift the vas deferens obstruction of some factors other than the semen can not be normal discharge into the female reproductive tract caused by male infertility, these patients have normal spermatogenic function, but due to sexual dysfunction, retrograde ejaculation or penile urethra abnormalities so that the semen can not be normal discharge into the female reproductive tract. Such as circumcision, retrograde ejaculation patients do bladder neck suture reduction, surgery for urethral stricture and plastic surgery for hypospadias and supraurethral cleft, etc. 4, through surgery to relieve the infertility of men caused by diseases of other organs of the body. For example, thyroidectomy for hyperthyroidism, pituitary tumor removal for hyperprolactinemia.
