He-man (4)
I believe the answer is:
stud
'he-man' is the definition.
(I know that he-man can be written as stud)
This is the entire clue.
(Other definitions for stud that I've seen before include "Horse-breeding establishment; jewellery item" , "Stallion for breeding - fastener" , "Collar button or animal farm" , "Horse-breeding place" , "Jewellery item; horse breeding establishment" .)
