It is known, however, that some of the most obvious paradoxical effects either are exerted indirectly, or depend on spe- cial experimental conditions. This subject is better discussed after some of the evi- dence has been presented. The Effects of Hormones on the Sex Ducts. Although the early differentiation of the gonaducts is independent of sex, they are regression (such as normally occurs in fe- males) is initiated (, Raynaud, '42; Greene, '42).

Although the early differentiation of the gonaducts is independent of sex, they are regression (such as normally occurs in fe- males) is initiated (, Raynaud, '42; Greene, '42). Paradoxically, it sometimes causes retention of the ducts in females (Greene). Male hormone induces retention and pre- cocious hypertrophy of the Wolffian ducts in both sexes. In mammalian embryos the epi- didymis also hypertrophies, and epididy- mides and seminal vesicles develop in fe-. VAS DEFERENS MESONEPHROS - BULBAR GLAND PHALLUS POUCH YOUNG - ± 10 DAYS.
