Spermaturia response of marsh frog males in recognition of chorionepithelioma

Recognition of chorionepithelioma in some cases is difficult due to the fact that the clinic of this disease is not specific. Therefore, any method that helps to clarify the diagnosis of chorionepithelioma is undoubtedly of practical importance. Histological examination is considered decisive for the final diagnosis. In addition to it, hormonal reactions are also used, in particular, the Ashheim-Tsondek reaction. In chorionepithelioma, as a rule, chorial gonadotropin is produced significantly more than in normal pregnancy. Therefore, the reaction is positive when the patient's urine is diluted 100, 200 or more times.
