[Testosterone production after in vitro stimulation of testicular cells with gonadotropins in bulls].
The response of bulls' testicular cells to the stimulation by serum gonadotropin ad us. vet. (Bioveta, Ivanovice in Haná) was investigated in in vitro tests. The testicular tissue was sliced, collagenase-split and the loosened cells were stimulated by gonadotropin concentrations of 7.8 to 250 I U per l; control samples without gonadotropin treatment were used for comparisons. The testicular cells responded to the increasing stimulation by higher production of testosterone.
