Sperm retrieval procedures are techniques used to obtain sperm directly from the male reproductive system when sperm cannot be obtained adequately through ejaculation or when other clinical circumstances require surgical retrieval. Different procedures may be considered depending on the underlying cause, sperm production, reproductive anatomy, and treatment plan. Techniques can include methods that retrieve sperm from the epididymis or testicular tissue, with the specific approach determined by a qualified medical team. Retrieved sperm may sometimes be used in assisted reproductive procedures
