Large penis and season of birth

[Bbucko]

January, and I meet the OP's criterion.

and would it be such a huge surprise spring babies have bigger dicks? Supposedly hormone kick into high gear in spring, and genital development is in 3rd trimester, IIRC.

I was born in February... not quite spring

I feel like this could be simpler-
Spring (above average)
Summer (above average)
Fall (above average)
Winter (above average)
Spring (avg/below avg)
Summer (avg/below avg)
Fall (avg/below avg)
Winter (avg/below avg)
Female

A problem with using seasons is that if the trend showed two peaks - as it currently does - about six months apart, and if they fell on the cusps of the seasons, you would get a flatline graph.

I doubt that the present indication will continue if we get many more hits, but the null hypothesis (season having no effect on penis size) would lead to all months getting about 8.3...% of the applicable entrants. (Problem: this software counts the "not applicables" within its percentages.) Instead we see quite a smooth curve with two peaks and two troughs.
