Mean plasma testosterone levels (+/- S.D.), using Sephadex LH-20 and competitive protein binding, were 629 +/- 160 ng/100 ml for a group of 27 normal adult men, 650 +/- 205 ng/100 ml for 27 impotent men with normal secondary sex characteristics, 644 +/- 178 ng/100 ml for 20 men with oligospermia, and 563 +/- 125 ng/100 ml for 16 azoospermic men. None of these values differ significantly. For 21 men with clinical evidence of hypogonadism the mean plasma testosterone (+/- S.D.), at 177 +/- 122 ng… CONTINUE READING
