Prolactin and thyrotropin response to thyrotropin-releasing-hormone in adolescent females with insulin-treated diabetes mellitus.

Prolactin and thyrotropin response to TRH and basal gonadotropins levels in blood were investigated in insulin-treated adolescent females with regular menstruation cycles (Group I) and menstruation disturbances (Group II) compared with control, healthy girls. No significant differences were found in TSH secretion after TRH administration and basal LH, FSH levels between the observed groups. Blood basal PRL levels were significantly lower in young females in Group II, and a highly increased mobilization of PRL secretion (delta % PRL)--masked hyperprolactinaemia--in all of the groups of diabetic girls was revealed. Cytological examination of vaginal smears confirmed hypoestrogenic status of girls from Group II compared with Group I and the control group.

Serum immunoglobulins IgG and IgM in the seminal plasma of men with normospermia, oligozoospermia, and azoospermia.

The seminal plasma of eight males with normospermia, seven with oligozoospermia, and eight with azoospermia was examined for the presence of IgG and IgM by means of double-gel immunodiffusion. IgG was present in every seminal plasma sample. The highest titers of IgG were found in azoospermic and normospermic samples, but the lowest IgG titers were seen only in normospermic samples. IgM was detected only in some cases, mainly in the azoospermic group. Testicular biopsy was performed in all the azoospermic patients, but IgM was found only in the cases demonstrating spermatogenic arrest and was not found in the cases with complete spermatogenesis. It is concluded that the IgM present in the seminal plasma was of testicular origin and was associated with injury of the male genital system.

Decrease of plasma somatotropin levels following thyroliberin (TRH) administration in patients with hyperthyroidism.

Thyroliberin was observed to induce a significant decrease of plasma somatotropin levels in patients with untreated hyperthyroidism, except those with very low initial somatotropin levels. These data have confirmed our previous finding where we noted that under the conditions of thyroid hormone excess thyroliberin was able to exert an inhibitory effect on somatotropin release.

Clinical, hormonal and semiological data in adult men operated in childhood for hypospadias.

Examination of 16 adult men operated in childhood for hypospadias revealed signs of moderate injury of the male genital system. It appears that accessory sexual glands were mainly responsible for the observed abnormalities. Since testicular position and size, serum testosterone and FSH levels were normal it seems that hypospadias and the accompanied disturbances are connected with reduction of responsiveness of target tissues to androgen stimuli rather, than with lesion of the testicle. The coexistence of normal serum testosterone and elevation of serum LH suggests the decrease of sensitivity of hypothalamic or pituitary receptors to negative feedback influence of androgens. The consciousness of sexual inadequacy noted in some cases was mainly of emotional character.
