[Level of immunoreactive follicle-stimulating hormone in the pituitary and blood of human fetuses].
The FSH content in the hypophysis and blood serum was determined by means of radioimmunology in 367 human foetuses at the age of 8 to 34 weeks. The immunoreactive FSH was detected in the hypophysis on the 9th week of embryogenesis. The ability of the hypophysis to release FSH in the blood was demonstrated for the female foetuses at the age of 14 to 34 weeks (with the maximum during the 17--18th week) and for the male foetuses at the age of 19 to 31 weeks. Sexual differences in the FSH content were shown in the hypophysis from the 14th till the 34th and in the blood serum from the 14th till the 26th week of development.
