sperm aspiration

A procedure in which a sample of sperm cells is removed from the testicle or epididymis through a small needle attached to a syringe. The sperm is looked at under a microscope in the laboratory, where it may be used right away to fertilize eggs or frozen for future infertility treatment. Sperm aspiration may be useful for men who have fertility problems caused by a blockage that keeps sperm from being ejaculated. It may also be useful for men who want to have children after having treatment that may cause infertility, such as certain cancer treatments. Sperm aspiration is a type of sperm retrieval method.
