Two pregnancies after in-vitro fertilization with spermatozoa from alloplastic spermatocoeles

Two case reports describe successful in-vitro fertilization (IVF) of oocytes of two 28-year-old women with epididymal spermatozoa aspirated from alloplastic spermatocoeles of the husbands. Both men suffered from complete ejaculatory failure, which was caused by paraplegia in the first and by radical surgery of an embryonic carcinoma of the testis in the second. Motile spermatozoa were aspirated in the first case 4 months after implantation of the spermatocoele, and in the second at 1 month. For the first couple, IVF treatment led to a singleton pregnancy; the child has since been born. In the second couple, IVF treatment resulted in a twin pregnancy, with intra-uterine abortion of one gestational sac. The resulting singleton pregnancy is still ongoing.
