Abstract
This case report presents a 31-year-old male patient with primary infertility, a unilaterally undescended testicle, and a complete AZFc microdeletion. Despite failed attempts at testicular sperm extraction, the patient underwent successful microscopic testicular sperm extraction and subsequent viable sperm extraction, leading to successful fertilization through intracytoplasmic sperm injection (ICSI). The report underscores the potential for successful ICSI in male infertility cases with complex genetic and reproductive issues, highlighting the importance of comprehensive genetic evaluation and individualized reproductive techniques in managing male infertility associated with undescended testicle and genetic anomalies.
