This article was a real eye-opener. I had no idea that children (and women, if you read the whole article) can be exposed to testosterone so casually, by skin contact with someone who has used the gel.
Kudos to the doctors who figured out what was going on. I'm sure these kids presented with "precocious puberty" and other signs and symptoms that must have been head-scratchingly unusual.
Just another reminder about how powerful testosterone can be, even in very small exposure amounts.
