Pregnancy method offers wild variation devoid of answers (2,5)
I believe the answer is:
in vitro
'pregnancy method offers' is the definition.
I can't judge whether this defines the answer.
'wild variation devoid of answers' is the wordplay.
'wild' indicates an anagram.
'devoid of' indicates named letters should be taken away.
'answers' becomes 'aa' (an abbreviation for answer written twice).
'variation' with 'aa' taken away is 'vrition'.
'vrition' is an anagram of 'IN VITRO'.
Can you help me to learn more?
(Other definitions for in vitro that I've seen before include "- - fertilisation (IVF)" , "Taking place in a test tube (Latin)" , "In an artificial environment outside the living organism (Latin)" , "Made to occur outside body (of biological process)" , "Having unusual conception" .)
