Comparative analysis of surgically retrieved sperms in cases of obstructive and nonobstructive azoospermia treated for infertility

Background: Azoospermia is a highly evolving subject in the last few decades. In the past, use of donor sperm was the only option providing a realistic chance of conception for couples affected by azoospermia. Introduction of sperm retrieval techniques and assisted reproductive technologies, especially intracytoplasmic sperm injection (ICSI), has provided these men a chance to father their genetically own child and changed the management approach significantly. Objective: The objective was to compare the sperm retrieval rate (SRR) and ICSI outcomes of surgically retrieved sperms in cases of obstructive and nonobstructive azoospermia (NOA) as well as to evaluate the efficacy of sperm retrieval techniques. Materials and Methods: A total of sixty azoospermic patients were included in the study. The patients were divided between OA (16) and NOA groups (44). A retrospective outcome analysis was done on SRR and ICSI results among them. Results: The overall SRR in patients with NOA and OA was 47.7% and 100%, respectively (P
