Serum levels of LH and FSH and the intratesticular concentrations of testosterone (T) and estradiol (E) were measured in biopsy tissue from 40 infertile men, aged 21-36 yr, of whom 21 were oligospermic men with varicocele and 19 were men with idiopathic oligospermia. Intratesticular T and E concentrations were negatively correlated (P less than 0.001) with testicular volumes, as measured with a calibrated orchidometer, suggesting that differences in measured intratesticular steroid levels in… CONTINUE READING
