Sounds like the vedic equivalent of viagra. I can already see many readers turning red with "blasphemy" written all over their red face. Well, I stand by the question. It is correct in its essentials.
This is not a complicated scientific question to answer. IMHO, a basic knowledge of physiology and voice production can provide the broader answers to this question. Vocal chords cannot be used to increase physical virility…
