Yes, many detailed studies indicating correlations with some body parts:

height - mild involving overall average penis size, moderate involving outlier penis sizes

shoe size - weak involving overall average penis size, moderate involving outlier penis sizes

flaccid to erect - strong correlation

fingers - strong correlation found involving index finger in only doctor study available on this. other fingers aren't mentioned in report, unclear whether other fingers were studied or not.

natural butt size - strongly correlated with penis size, but only one doctor study available on this

girth and length strongly correlated

Many people don't understand what the word correlation means and think that so long as an exception exists no correlation exists. There does not have to be an absolute for a correlation to exist. Correlations can range from none to weak to mild to moderate to strong. It's now believed there are genes sharing penis and some body parts components. Since many factors go into developing an individual the correlations are not absolutes.
