Female Barbary monkeys often utter loud, distinctive calls before, during or after sex - and for years, researchers have debated the reasons for all the shouting. German scientists reported that the shouts appear to help the male partner reach sexual climax. Part of the researchers' job was to count the males' pelvic thrusts - a task that primatologist Dana Pfefferle admitted was "quite weird." But sometimes doing science requires that kind of sacrifice. "You get used to it," Pfefferle said.
