About this trial
This is an interventional basic science trial for Non-obstructive Azoospermia focused on measuring Non-obstructive Azoospermia, Sperm Retrieval, Infertility, Male, Semen, Biomarkers, Proteomics, Enzyme-Linked Immunosorbent Assay
Eligibility Criteria
Inclusion Criteria:
- Diagnosed with NOA by standard clinical means with a minimum of 2 semen tests confirming that the man is azoospermic
- Ability to understand the study and consent
- Ability to deliver semen samples
Exclusion Criteria:
- Men do not have NOA
- Cannot understand the study and consent

Arms of the Study
Arm 1
Arm Type

Arm Label
TEX101
Arm Description
This is a single arm study. All patients will be asked to provide multiple semen samples and all samples will be tested with TEX101 ELISA assay. Timing of mTESE maybe changed according to the assay results.
Outcomes
Primary Outcome Measures
Successful testicular sperm retrieval
This outcome will be measured by if sperms would be found during the procedure or if sperms would be identified in the IVF clinic.
Secondary Outcome Measures
Natural variation in sperm counts in semen
Variation in sperm concentration in semen as measured by direct microscopic assessment of different semen samples provided by each of the participants.
Natural variation in semen TEX101 concentration
Variation in TEX101 concentrations in semen of different semen samples provided by each of the participants as measured by the TEX101 ELISA assay.

5. Study Description
Brief Summary
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.
Detailed Description
This is a non-randomized pilot study. All men with NOA, who may or may not consider having mTESE, will be approached to enter this study.
Recruited men will have a semen test performed at the initial visit (time 0) to measure semen TEX101 levels using an ELISA assay.
For men who are not considering a mTESE to retrieve sperm, the TEX101 semen levels will be measured monthly for three months to determine the variability of semen TEX101.
For men who are considering a mTESE in an attempt to retrieve sperm, the mTESE procedure to retrieve sperm will be booked. If the level of TEX101 is detectable at time 0, then the men will have semen testing monthly. If the TEX101 is persistently detectable then the men will have surgery at the time originally scheduled. If the TEX101 drops on any subsequent test to be undetectable, then the semen testing for TEX101 will continue monthly for a maximum of 3 additional months. If the TEX101 remains undetectable for all tests, the men will have the mTESE at the end of the additional 3 months. If the TEX101 is detectable on a subsequent test, then the men will undergo an immediate mTESE (< 2 weeks).
If the initial TEX101 is undetectable, then the men will have monthly semen testing for TEX101 for a maximum of 3 additional tests. If the TEX101 remains persistently undetectable, then a mTESE will be performed as originally booked. If the TEX101 is detected on a subsequent test, then an immediate mTESE (< 2 weeks) is performed.
