LOS ANGELES, DALLAS–The fast-falling numbers of horses bred
to produce estrogen supplements made from pregnant mares’ urine are
expected to drop further after publication of new findings from the
U.S. government-funded Women’s Health Initiative linking estrogen
supplements to elevated rates of death from breast cancer and risk of
developing kidney stones.
The new findings came eight years after the Women’s Health
Initiative in July 2002 reported thatestrogen supplements appear to
be linked to increased risk of women suffering heart attacks,
strokes, and blood clots in their lungs.
