If men were equally at risk from this condition - if they knew their bellies might swell as if they were suffering from end-stage cirrhosis, that they would have to go nearly a year without a stiff drink, a cigarette, or even an aspirin, that they would be subject to fainting spells and unable to fight their way onto commuter trains - then I am sure that pregnancy would be classified as a sexually transmitted disease and abortions would be no more controversial than emergency appendectomies.
