All participants underwent TEFNA. The primary outcome measure was the TEFNA success rate in retrieving mature sperm.

Retrieval of up to ten sperm cells occurred in 11 procedures (25%); ten procedures (22.7%) resulted in producing dozens of sperm cells, and 100s to 1000s of sperm cells were obtained from the remainder of 23 procedures (52.3%).
