Regarded as harmless by top gynaecologist in African country (6)
I believe the answer is:
benign
'regarded as harmless' is the definition.
I can't tell whether this defines the answer.
'top gynaecologist in african country' is the wordplay.
'top' indicates taking the first letters (in a down clue, the first letter is top).
'in' means one lot of letters goes inside another.
'african country' becomes 'benin' (country in Africa).
The first letter of 'gynaecologist' is 'g'.
'g' put within 'benin' is 'BENIGN'.
'by' is the link.
Can you help me to learn more?
(Other definitions for benign that I've seen before include "Favourable" , "Mild and gentle, not malignant" , "Salubrious" , "Genial; not harmful" , "Obliging" .)
