SUMMARY

Large doses of human chorionic gonadotrophin and human pituitary follicle-stimulating hormone were given singly and in combination to six eunuchoidal men. None had an increased excretion of urinary gonadotrophin before treatment.

Histological examination of the testicles showed very immature germinal epithelium in five of the patients before treatment. Spermatozoa were found histologically in three patients, only after combined treatment with both gonadotrophins. Low concentrations of spermatozoa appeared in semen from two of these patients.

One patient was found to have histological evidence of spermatogenesis before treatment but was unable to produce semen. Treatment with chorionic gonadotrophin alone enabled him to produce semen containing up to 15,000,000 spermatozoa per ml.

Significant increases were found in the urinary levels of a variety of steroids and in total body potassium after treatment with chorionic gonadotrophin and a variable amount of somatic development took place.

SUMMARY

The effect of testosterone injections on the histology of the submaxillary salivary glands, and their content of nerve growth factor (NGF), were studied in normal and gonadectomized male and female mice, and in those affected with testicular feminization (due to the X-linked gene, Tfm). In intact and spayed female and castrated male mice testosterone increased the quantity of NGF and caused the histology of the glands to become like the male type. In mice with testicular feminization both the histology and the NGF content were of the female type, and were completely unaffected by testosterone injections. Female mice heterozygous for Tfm responded to testosterone, but in some the response appeared intermediate. The submaxillary gland provides a suitable test organ for studies of the androgen insensitivity of Tfm mice, and may prove more useful than the kidneys for some experiments.

SUMMARY

Adult male rats were treated with daily s.c. doses of 10 mg. cyproterone acetate for 3 weeks. Histological examination of the exorbital lacrimal glands at the end of treatment showed distinct differences compared with male controls: the histological picture showing greater resemblance to the glands of female controls. In orchidectomized rats receiving substitution treatment with testosterone propionate, cyproterone acetate 'neutralized' the effect of testosterone propionate on the exorbital lacrimal gland to a considerable extent. The possibility that this gland may play a part in the sexual behaviour of the rat is discussed.
