[Increase of the number of oogonia in the ovary of fetal rabbit hypophysectomised by decapitation. Probable role of thymus].
A significant increase in ovarian volume and in the numbers of germ cells was observed in rabbit foetuses hypophysectomised by decapitation on day 19 and killed on day 28 when compared with unoperated females of the same litter. It seems that the hypophysis acts indirectly while the foetal thymus has a likely direct role.
