They help you conceive boys/girls: to me that's extraordinary (13)

I believe the answer is:

embryologists

I'm a little stuck... Click here to teach me more about this clue!

'they help you conceive' is the definition.
The definition suggests an adverb but the answer is not.

'boysgirls to me that's extraordinary' is the wordplay.
'that's extraordinary' is an anagram indicator.
'boysgirls'+'to'+'me'='boysgirlstome'
'boysgirlstome' anagrammed gives 'EMBRYOLOGISTS'.

Can you help me to learn more?
