"....[Those] defined having a micropenis with a stretched penile length of less than 9.3 cm were constituted the study group. Mean stretched penile length was 6.81.6 cm (range 3.6–7.8 cm). Karyotype analysis showed 46XY in all cases."
http://www.nature.com/ijir/journal/v17/n3/abs/3901292a.htmlA micropenis is medically considered 'ambiguous genitalia'. This alone would be highly functioning intersexed person in my opinion. Checking fertility levels could show hypogonadalism, lessened masculinization of skeleton or infertility etc.
Having had undescended testicles? I'd have a fertility check, I'd say yes even if the fertility test is positive.
Personally I could see how much I had in common with women even as a man, I was female though, something I'd been denying all my life. But so much of gender is choice though.
