I didnt know that about humans. Fascinating. This reminded me of a friend's sow who had given birth several times quite successfully, had a prolapse and was sent to the local abattoir. Friend knew the staff well and when collecting the carcass (it was some time before all the recent regulations) one of the slaughtermen asked her why she had called her male pig Roseanne. Apparently the pig had all the male organs as well on the inside. (I never really believed her until reading this).
