FIG. 21. Development of a genetic female of Xenopus treated with testosterone. A,
adult control female from which one ovary has been removed; B, female of the same age
treated with testosterone during larval life (compare with Fig. 20C). Ovaries laciniate,
with development retarded. (After Gallien.)

(intersexuality in genetic males).
The teratogenic action of the steroid sex hormones is manifested in
various species by the complete inhibition of the primordia of the female
genital tract (Mullerian ducts) and of somatic organs such as the mesoFIG. 22. Ovotestis of a genetic male Xenopus treated with testosterone. (After Gallien.)
