Cutter sail, possibly nut-related? (10)

I believe the answer is:

testicular

'nut-related?' is the definition.
(nut is slang for testicle)

'cutter sail possibly' is the wordplay.
'possibly' indicates an anagram.
'cutter'+'sail'='cuttersail'
'cuttersail' is an anagram of 'TESTICULAR'.

I've seen this clue in The Guardian.
