Andrology (from Ancient Greek: ἀνήρ, anēr, genitive ἀνδρός, andros, "man"; and -λογία, -logia) is the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is also known as "The science of Men". It is the counterpart to gynaecology, which deals with medical issues which are specific to the female reproductive system.
