Product from, for example, both sides of gonads (4)
I believe the answer is:
eggs
'product' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'for example both sides of gonads' is the wordplay.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'both sides of' means to remove the middle letters (only the letters on the sides remain).
'gonads' with its middle removed is 'gs'.
'eg'+'gs'='EGGS'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for eggs that I've seen before include "Urges (on)" , "Contents of nests" , "Ova" , "Bacon and - -" , "Levels (of quality)" .)
