Inhibin A and B dimers show diagnostic value in pregnancy, ovarian cancer, and male fertility. Further research is needed to confirm other applications for inhibin and activin assays in clinical practice.
Area of Science:
- Reproductive Endocrinology
- Biomarker Discovery
Background:
- Inhibins and activins are key paracrine/autocrine signaling molecules in reproduction and development.
- Diagnostic applications for these molecules are under investigation.
Purpose of the Study:
- To review the current diagnostic applications of inhibin and activin assays.
- To assess the potential of these assays in clinical practice.
Main Methods:
- Enzyme-Linked Immunosorbent Assays (ELISAs) for inhibin A, inhibin B, and free inhibin alpha subunits were analyzed.
- Evidence for existing and potential diagnostic uses was reviewed.
Main Results:
- Inhibin A is useful in Down syndrome screening during pregnancy.
- Total inhibin can serve as a marker for ovarian cancer in specific cases.
- Inhibin B is a valuable diagnostic for male fertility.
Conclusions:
- Specific inhibin assays have established diagnostic roles.
- Broader applications of inhibin and activin assays require further validation for clinical use.
