Effect of short-term scrotal hyperthermia on spermatological parameters, testicular blood flow and gonadal tissue in dogs.

The objective was to assess the effect of a short-term scrotal hyperthermia in dogs on quantitative and qualitative ejaculate parameters, testicular blood flow and testicular and epididymal histology. After a control period, the scrotum of seven normospermic adult beagle dogs was insulated with a self-made suspensory for 48 h. Nine weeks later, two animals were castrated, while in five animals, scrotal hyperthermia was repeated.

[Clinical signs, diagnostic approach and therapy for the so-called ovarian remnant syndrome in the bitch].

The ovarian remnant syndrome arises as a consequence of incomplete ovariectomy or ovariohysterectomy. Remnant ovarian tissue which has been left mostly unintentionally in the bitch may show endocrine activity a few weeks to several years after surgery, provoking a variety of clinical signs. The majority of affected bitches return to heat, in other cases signs of pseudopregnancy and endometritis may be observed.
