Flagging because it seems too political, but in case I'm wrong: I can't compare, but I heard it's easier for women to keep their legs together for long periods

Flagging because it seems too political, but in case I'm wrong: I can't compare, but I heard it's easier for women to keep their legs together for long periods of time than for men. Possibly something to do with thermoregulation of testicles. Also, cases of complaining about "manspreading" when there's plenty of room around make me wonder how much is it about being space efficient and how much about just comntemporary feministic misandry. Is there any scientific data about this subject, supporting either of sides?
