Male Infertility; Sperm Retrieval; Fertility preservation

For patients experiencing obstructive azoospermia (OA), non-obstructive azoospermia (NOA), or ejaculation disorders, utilizing and storing sperm obtained through testicular sperm aspiration (TESA) or testicular sperm extraction (TESE) often represents a viable method for preserving fertility by retrieving tissue. The primary goal of sperm retrieval is to obtain high-quality sperm in sufficient quantities for immediate use or cryopreservation while minimizing the risk of injury to the reproductive structures. The video outlines the most common causes of both NOA and OA and briefly reviews several techniques for sperm retrieval described in the literature. We provide step-by-step guidance of office based TESA and conventional TESE, offering a high-quality virtual resource for urologists to enhance their skills in these techniques. We also emphasize tips and tricks for local anesthesia, necessary materials, and strategies to improve efficacy when working without an assistant.
