...working together to find a way of helping subfertile women ovulate, and thus conceive. They first had to regularize the woman's cycle, and they hit upon a synthetic progestin chemically akin to another female sex hormone, progesterone. The progestin, taken for 20 days in mid-menstrual cycle, suppressed ovulation by simulating pregnancy. Taken off the medicine, the women had a more normal cycle, with surer ovulation. After Pincus and Rock had produced a gratifying number of conceptions, a new idea struck them: Why not use the progestin deliberately to suppress ovulation every month-in other words...
Female hormones will also suppress a man's sperm production-the present pills do this-but they lower both libido and potency, along with more dangerous side effects. Vaccinating a woman against her husband's sperm, or vaccinating him against his own, has been investigated by Dr. Tyler's biologist brother Albert, with poor results...

"Whoever helps the oligarchies where our guerrillas are fighting is helping suppress the revolution. What would the revolutionary Vietnamese think if we sent delegations to South Viet Nam to trade with the puppet government of Saigon...
...treating patients with transplants, doctors have been teetering on a precarious seesaw. They must use drugs enough to suppress the immune mechanism and spare the kidney, but not in such strong dosages as to let the patient die from any passing infection. The drugs used, mainly azathioprine (Imuran) and prednisone, are so highly potent that by themselves they can seriously weaken or help to kill a patient. A major factor in boosting the cure rate in the past two years, said Dr. Murray, has been a steady reduction in the dosage of azathioprine. The researchers gathered at Duke were seeking...
...Miller, 24, became the first person to be convicted under a new law that makes card burning punishable by a $10,000 fine or five years' imprisonment, or both. When Miller appealed his suspended three-year sentence, he argued that Congress had enacted the law deliberately to suppress dissent. Indeed, the bill's proponents made no secret of the fact that it was aimed at "beatniks"-meaning critics of the U.S. war effort in Viet...
