Effect of flutamide on the physiological status of epididymis and epididymal sperms.

abstract：:In 1982, 89 men from all over the FRG participated in an investigation of sperm density and the presence of selected persistent environmental chemicals in their semen. Semen concentrations for the following chemicals were measured: lead, cadmium, hexachlorobenzene (HCBC), a-hexachlorocyclohexane (a-BHC), DDT and metab...
