Do men have mammary glands?
Mammary gland
Male mammals typically have rudimentary mammary glands and nipples, with a few exceptions: male mice do not have nipples, and male horses lack nipples and mammary glands. The male Dayak fruit bat has lactating mammary glands. Male lactation occurs infrequently in some species, including humans.
Male accessory gland
The male accessory glands are the ampullary gland, seminal vesicles, prostate, bulbourethral gland, and urethral glands.
