Intrauterine insemination with spermatozoa recovered from the aspirate of artificial spermatocoele

Abstract

Congenital absence of both vas deferens accounts for approximately 10% of cases of obstructive azoospermia. The purpose of the present study was to develop a treatment protocol for a group of azoospermic patients using surgical implantation of alloplastic spermatocoele to enable repeated sperm cell aspiration. Nine patients with congenital absence of both vas deferens, two with obstructed and one with destroyed vas, underwent surgery for the implantation of an alloplastic spermatocoele. In 10 of the 12 patients, vital spermatozoa were recovered from the aspirate and used for intrauterine insemination of their female partners with induced ovulation, some of whom then conceived.
