Key facts

Testis expressed Protein 101 [Mass/volume] in Semen by Immunoassay
Testis expressed Protein 101
This term represents an assay for a testis-specific glycoprotein that is highly expressed in spermatocytes and spermatids. This biomarker is used to assess male fertility, with levels below 0.2 ng/mL being highly predictive of sperm retrieval failure in karyotypically normal men with non-obstructive azoospermia.
