Men Only organ writing about article in Times (8)
I believe the answer is:
prostate
'men only organ' is the definition.
'writing about article in times' is the wordplay.
'writing' becomes 'prose' (I've seen this in other clues**).
'about' indicates putting letters inside.
'article' becomes 'a' (indefinite article).
'in' is an insertion indicator.
'times' becomes 'tt' (two abbreviations for time).
'a' put inside 'tt' is 'tat'.
'prose' placed around 'tat' is 'PROSTATE'.
(Another definition for prostate that I've seen is " A protest about a troublesome male gland".)
