Abstract

Sperm retrieval techniques have been developed to allow sperm acquisition directly from the epididymis or seminiferous tubules to treat azoospermia-related infertility with the aid of intracytoplasmic sperm injection (ICSI). Nowadays, testicular sperm retrieval has also been used to overcome infertility in non-azoospermic men with high levels of ejaculated sperm with damaged chromatin. In this chapter, we describe the existing sperm retrieval techniques and the predictive factors for sperm retrieval success in both obstructive azoospermia and nonobstructive azoospermia. Furthermore, we provide readers an overview of the laboratory methods to process surgically extracted gametes. Lastly, we summarize ICSI outcomes using sperm harvested from the epididymis and testis in azoospermic and non-azoospermic men, including data concerning the health of resulting offspring.
