Sample spice sent to males (8)
I believe the answer is:
specimen
'sample' is the definition.
(I know that specimen is a type of sample)
'spice sent to males' is the wordplay.
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'to males' becomes 'men' (man is a kind of male).
'spice' anagrammed gives 'speci'.
'speci'+'men'='SPECIMEN'
(Other definitions for specimen that I've seen before include "Representative sample" , "Typical example - sample" , "blood sample" , "Sample to be studied" , "Sample taken for medical testing" .)
