Placental allopregnanolone affects oligodendrocyte differentiation and myelination in the developing cerebellum. Male mice deprived of allopregnanolone in utero show impaired sociability and communication in later life; their female littermates are unaffected. Allopregnanolone replacement restores normal myelination and behavior.
