Woman's nether regions bitten by rodents (8)
I believe the answer is:
michelle
'woman's' is the definition.
'nether regions bitten by rodents' is the wordplay.
'nether regions' becomes 'he'll' (I've seen this in another clue).
'bitten by' means one lot of letters goes inside another (I've seen this in other clues).
'rodents' becomes 'mice' (mouse is a kind of rodent).
'hell' going within 'mice' is 'MICHELLE'.
(Other definitions for michelle that I've seen before include "Girl's name" , "Lass" , "Beatles' song; name" .)
