Undescended testis: Fate of fertility predicted by blood biomarkers

In boys with undescended testis, the risk of developing infertility is traditionally predicted based on a decrease in germ cell count observed using testicular biopsy samples. However, the process of testicular biopsy carries the risk of injury, infection, and developing subfertility. In a new study, researchers from Japan have identified an alternative means of predicting future infertility based on serum sex hormone ratios without performing the testicular biopsy.
