Offspring matter (5)

I believe the answer is:

issue

This clue is a double definition.

'offspring' is the first definition.
(I know that offspring can be written as issue)

'matter' is the second definition.
(I know that matter can be written as issue)

(Other definitions for issue that I've seen before include "particular edition of magazine?" , "Offspring or one of publication" , "Regular publication" , "Topic (to be addressed)" , "Offspring; publish" .)

I've seen this clue in The Everyman puzzle in The Observer.
