After turning, male degenerates charge (5)
I believe the answer is:
storm
'charge' is the definition.
(I've seen this before)
'after turning male degenerates' is the wordplay.
'after turning' shows that the letters should be reversed in order.
'male' becomes 'm' (common abbreviation).
'degenerates' becomes 'rots' (rotting is a kind of degenerating).
'm'+'rots'='mrots'
'mrots' in reverse letter order is 'STORM'.
(Other definitions for storm that I've seen before include "Gale, tempest" , "rage" , "Very unfavourable climate" , "SECOND PART OF 1 DOWN" , "X-Men character" .)
