Talk me out of giving my newborn son PTU so he gets reversible hypothyroidism
>Our previous studies have shown that transient neonatal hypothyroidism, induced by treatment with the reversible goitrogen 6-propyl-2-thiouracil (PTU), increases testicular size and daily sperm production in the adult rat by up to 82% and 136%, respectively.

>+136% increase in testicle volume

Just give your newborn son reversible hypothyroidism for a couple of weeks and he will have massive testicles and be a high test beast when he's an adult. There's literally no downside to this, why shouldn't I do it?
