Summary

This observational study aims to identify and classify Traditional Medicine (TM) syndromes in men aged 18 to 60 with male infertility and oligoasthenoteratozoospermia (OAT) syndrome. Researchers will first review TM literature to list symptoms, then survey 300 participants and use mathematical models to group them into syndrome subtypes. The goal is to better understand TM patterns in this condition, not to test a treatment.
