男科学（英语：andrology，来自古希腊语：ἀνήρ、anēr，属格ἀνδρός、andros「男人」和-λογία：「学」）是处理男性健康的医学专业人士，特别是与男性特有的男性生殖系统和泌尿外科等相关的问题。与针对女性生殖系统相关的医疗问题的妇产科互相对应。自1960年代后期以来，男科学只做为一个独特的专业来研究：第一个有关该课题的专业期刊是德国期刊「Andrologie（现称「Andrologia」）」，自1969年起出版。

男性特有的医学和手术进程包括输精管结扎术和输精管吻合术（输精管结扎的逆转进程之一）以及应付男性泌尿生殖系统紊乱的介入进程，例如以下列表：

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. 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.
