[Possibilities of treatment of maldescensus testis in the dog (author's transl)].

Abstract

The diagnosis of inguinal retention of the testis can be made in the dog from the 10th week of life. Like in man, therapy of this condition can be done with gonadotropins or releasing hormones. In conditions with retention of the testicles in the upper inguinal region LH-RH proved to be more successful than gonadotropin. 10 out of 16 patients showed a complete descent of the testes. In addition the effect of plasmagonadotropin as well as urinary chorionic gonadotropin, and of LH-RH on the plasma testosterone levels of juvenile and adult dogs was studied. It could be seen that in the young dogs all 3 hormones caused an increase in plasma testosterone, while in the adult animal only LH-RH was able to produce a significant rise.
