All correlations are highly significant (p < 0.001).

Test. T0: serum testosterone concentration before hCG injection, Test. T2: serum testosterone concentration 2 h apres hCg administration.

Estr. T0: serum estrogen concentration before hCG injection, Estr. T2: serum testosterone concentration 2 h after hCg administration.

STD, seminiferous tubule diameter.

TLCH, Total Leydig cell number.

PMLC, Percent mature Leydig cells.
