Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The investigators hypothesize that sperm production varies with time in men with no sperm in semen (non-obstructive azoospermia, NOA) and that the semen protein, TEX101, is able to monitor these changes. The investigators further hypothesize that TEX101 levels may be used to predict the optimum time for microsurgical testicular sperm extraction (mTESE) to provide the highest successful rates of sperm retrieval.
