Seminiferous tubule hypercurvature: A newly recognised common syndrome of human male infertility.
Testicular biopsy specimens from 42 of a series of 70 consecutive cases of primary male infertility and from 25 normal controls were morphometrically analysed. Although all the specimens from infertile males were normal by conventional histological standards, stereological measures of curvature in histological sections showed that cases of idiopathic male infertility had an abnormally increased curvature of seminiferous tubules.
