A suction technique similar to the vacuum-aspiration process that is now the most common form of first-trimester abortion, it requires a 50-mL syringe attached to a flexible plastic tube, which withdraws the contents of the uterus and deposits them into a closed container...

And the tissues of the vagina, though tougher than those in the anus, can also be torn during intercourse. A man, however, is exposed to vaginal secretions only during the sexual act itself. Unless he has genital ulcers or a cut on the penis, the chances of being infected are small...
...while working with patients with severe sperm deficiencies that researchers noticed something surprising. Eggs whose shells had been poked open were doing a much better job of sticking to the uterus wall. In a trial performed by Dr. Jacques Cohen, one of the scientists who developed the PZD procedure, embryos successfully lodged in the womb at a rate more than five times the national average for IVF. "I was so excited I couldn't sleep at night," says Cohen. Apparently eggs with a hole in their outer membrane somehow benefit from that hole. Cohen theorizes that embryos that...
