Crossword Genius

My, male showing a bit of resistance! (3)

Ross

I believe the answer is:

ohm

'a bit of resistance' is the definition.
(I've seen this in another clue)

'my male' is the wordplay.
'my' becomes 'oh' (both are expressions of surprise).
'male' becomes 'm' (common abbreviation).
'oh'+'m'='OHM'

'showing' is the link.

(Other definitions for ohm that I've seen before include "SI unit of electrical resistance" , "A little resistance" , "measure of resistance" , "Unit of electrical resistance (3)" , "physical unit" .)

I've seen this clue in The Times.
