[Inhibitory effect of some antrogenic hormones, administered in ovo after sex differentiation, on the development of Müllerian ducts in female bird embryos].

Some androgenic hormones injected into the vitellus of quail (8 and 10 days old) or chick eggs (10 and 12 days of incubation) inhibit the left Müllerian duct development and mainly that of the shell gland. They slow down or stop the right duct involution. After these effects, histo-pathogenic disturbances, affect them.
