The story of the word

Nineteenth-century zoologists needed one word covering ovary and testis, since in many animals the organ is the same until it differentiates, and built gonas from γονή, seed. The root goes back to the verb for being born and is the same family as γένος, so gene, genesis and gonad are cousins. Gonorrhoea is the plainest relative: Galen's name for the disease means a flowing of seed, which was a misreading of the discharge.
