Not sure about height, but supposedly transdermal DHT can increase penis size if you are in good health and diligent about applying it. Transdermal T might also influence it as well. There are tons on anecdotal reports of women experiencing clitoral growth from applying T and Dht cream. The Alphagels guy claims that several of his male clients have experienced penile growth from applying topical DHT.
Speaking from personal experience, I've noticed some flaccid growth (length) from foreskin restoration and topical DHT (girth). I have fairly poor EQ so I'm not sure where I'm 'maxing' out but it does seem like the flaccid gains do translate over to erect gains to some extent.
