Andrology (from , aner, genitive , andros, "man"; and , -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. However, unlike gynaecology, which has a plethora of medical board certification programs worldwide, andrology has none. Andrology has only been studied as a distinct specialty since the late 1960s: the first specialist journal on the subject was the German periodical Andrologie (now called Andrologia), published from 1969 onwards.
