Despite those concerns he said -- that research on the pill might be used in an attempt to take it away -- he said research needed to be done to give women a better way of evaluating their decision to use contraception.
"This story could be abused," he said. "[But] certainly we need to do the science to find out exactly how the pill can affect people's behavior -- mating preferences and otherwise."
In the end, researchers recommended that contraceptive use be a personal decision. As one of the authors noted, women shouldn't take studies of contraceptives and mate preference to mean that they should drop birth control as a knee-jerk reaction.
"It's up to everyone themselves to evaluate any costs and benefits of the pill in their personal circumstances, and as we make clear, the pill has a whole range of many positive effects too that cannot be overseen," said Lummaa. "I met my current boyfriend on the pill, and I am not too worried."
