Spermatogenesis, which takes place in the seminiferous tubules of the testes, is the orderly process during which spermatogonia evolve into mature spermatozoa. A chemical known as lonidamine prevents developing sperm from staying attached to the cells lining the seminiferous tubule and causes infertility in rats and men, says the Population Council's C. At 180 mg/kg/day, (which produces exposure levels 22 times higher than those in humans taking 80 mg/day based on surface area, mg/m2), seminiferous tubule degeneration (necrosis and loss of spermatogenic epithelium) was observed. |
