P>The aetiology of cryptorchidism is still undiscernible in the majority of cases. It has long been argued that cryptorchidism reflects a primary testicular maldevelopment, where the contralateral scrotal testis also suffers from aspermatogenesis and low spermatogonia count. The aim of the study was to determine the reproductive outcome of ex-cryptorchid men with azoospermia post-orchidopexy after testicular sperm extraction (TESE) and intracytoplasmatic sperm injection (ICSI). In a retrospective analysis, we compared the sperm retrieval, fertilization, pregnancy and live birth rates after ICSI of consecutive ex-cryptorchid azoospermic patients (n = 15) undergoing TESE between Jan 2000 and Dec 2007 vs. non-cryptorchid azoospermic men (n = 142). Sperm retrieval rate of ex-cryptorchid men by TESE (66%) was comparable with non-cryptorchid men (47%) (p = 0.15) despite significantly higher FSH levels (30.7 +/- 25.4 vs. 17.9 +/- 14.8 respectively) (p = 0.018) and a more prevalent histopathology diagnosis of aspermatogenesis (75% vs. 40%, p = 0.046). Fertilization (43.3%), pregnancy (30%) and live birth (20%) rates after TESE-IVF-ICSI in the ex-cryptorchid group were not different from the non-cryptorchid group (48.7, 43 and 29%, p = 0.26, p = 0.21, p = 0.29 respectively). We conclude that the reproductive outcome of ex-cryptorchid men with azoospermia post-orchidopexy employing TESE-IVF-ICSI is comparable with non-cryptorchid azoospermic men.
