[Gonad development and differentiation in the golden hamster].

Development and gonadal differentiation in the Golden Hamster embryo are studied from day 9 of development to adult stages by means of histological, histochemical and cytogenetical techniques. The gonad appears on the day 9 of development and remains in an indifferentiated stage until day 11, testicular differentiation is carried out from day 12 with testicular cords and Leydig cells. Ovarian differentiation occurs later from day 14 of development and is practically recognizable after birth.
