Abstract |
The authors have studied LH and FSH behaviour under basal conditions and after stimulation with GnRH in groups of subjects associated by the common denominator of more or less marked compromission of gonadal activity (subjects of both sexes in old age, affected by Sertoli cells only, Klinefelter's and Turner's syndromes ans subjects with congenital anorchia or with rudimentary testes) and have compared such behaviour with that shown by control groups. Special importance was given to the behaviour of LH/FSH ratio, which is significantly reduced in almost all the situations studied. To conclude, from the results obtained, the authors have evidence new elements to better single out the mechanism of homeostatic regulation of gonadotropic incretory system, with special consideration for what happens to FSH, and also useful indications to emphasize the semeiological use of LH/FSH ratio relevant to basal values and chiefly to incretory areas.
