[Differential diagnosis in potency disorders].

Disorders of sexual libido are seldom organic, in general they are of psychological origin. It is, however, difficult to obtain a differential diagnosis. One of the first diagnostic considerations must be the establishment of primary or secondary libidinal dificit, or indeed, whether there is no libido at all. In cases of libido disorders with primary libido dificit, depression, organic disease, or side effects of pharmaca may be the cause. Libido disorders in the presence of functional libido, however, must be regarded as primarily psychologically caused. An exception are libido problems in the presence of diabetes mellitus and peripheral vasculatory defeciencies. In these cases libido is either totally absent or appears only secondarily. The symptomatology of libido disorders in the presence of depression, diabetes melitus, and peripheral vasculatory disturbancies, as well as psychologically caused erectile and ejaculatory difficulties are discussed in detail. These groups are compared with respect to libido and behavior involving erection, ejaculation, anxiety and avoidance.

Further studies on sex hormones in male homosexuals.

Plasma estrone, dihydrotestosterone, luteinizing hormone (LH), and percentage-free testosterone levels were determined in 26 predominantly or exclusively homosexual males (20 to 33 years of age) and in an age-matched control group. Although the homosexual and control groups showed a broad overlapping for all hormonal factors measured, highly significant differences between the groups were found without exception. The medians of the homosexual group (control group) and the significance levels for the two-sample rank tests were as follows: estrone 3.07 (2.43) ng/100 ml, P less than .01; dihydrotestosterone 66.0 (49.2) ng/100 ml, P less than .01; percentage-free testosterone 10.7% (9.7%), P less than .02; LH 35.1 (24.9) ng/ml, P less than .001. These findings can in part be explained by the higher LH secretion in the homosexual subjects.

Pharmacokinetics of 5,6-trans-25-hydroxycholecalciferol, a synthetic analogue of vitamin D3, in man.

Vitamin D analogues of high biological activity are probably useful in the treatment of renal osteodystrophy. The pharmacokinetics of the synthetic compound 5,6-trans-25-hydroxycholecalciferol have been studied in healthy subjects who were of normal vitamin D status. In comparison to natural 25-hydroxy-cholecalciferol, serum levels of the analogue were lower and its half-life in blood after oral or intravenous administration was considerably shorter. In normal subjects no increase of dihydroxylated metabolites in serum was observed within seven days of an intravenous dose.

Systematic desensitization of erectile impotence: a controlled study.

Results of a study conducted to assess the therapeutic effectiveness of systematic desensitization of erectile impotence are described. Three groups of eight patients each were formed. They were treated with systematic desensitization or conventional medication and general advice, or put on a waiting list. Therapeutic effects were investigated on the behavioral, subjective, and physiological levels. There were no significant differences among the three groups except on the subjective level. On this level, after therapy the systematic desensitization group rated feelings in sexually arousing situations as associated with significantly less anxiety than the other two groups. Systematic desensitization used alone as a treatment for erectile impotence shows only limited therapeutic effect. The unimproved patients were later treated using a modification of the Masters and Johnson technique. Early results suggest that this technique may be superior to systematic desensitization alone.
