I'd also like to know a little bit more about the statistics. Was it 239 gay and bi men (in which case how was the control group matched for age, family background etc) or a random sample, in which case, assuming 1 in 10 people are gay, we are actually looking at something like 23 men. How significant was the link? What other questions did they ask that came up with no significant link? I assume they didn't set out to prove the big families = gay link, originally.

I would like to believe there's a meaningful study here, albeit limited in numbers, that the media have blown out of proportion. (I think that was the case for the brain size study - MRIs are expensive and difficult to do so a small group makes sense, they were studying a particular measurement, not every detail of brain structure.) However, this study seems pretty pointless to me.
