Once upon a time, knowledge of ancient Greek was mandatory if one wished to become a doctor.

Perhaps that’s why so many scientific and medical terms have been generated using Greek words.

The hormones that are best known to the layperson are the so-called sex hormones (progesterone, estradiol, testosterone, etc.). Many lay people mistakenly hear “sex hormones” every time the word “hormone” is uttered.
