Breast is more or less normal.

Breast is generally 10 to 20 mm normal. Mammary gland is an accessory gland of skin, and it is a kind of compound tubular vesicular gland. Male breasts gradually degenerate at about one and a half years old, with ducts in the glands, but no acini and no leaves. Female mammary glands proliferate in adolescence, and after menstruation begins, the mammary glands are nearly mature.
