为了查明性行为是否会改变男性较大的这块大脑区域，埼玉大学的研究人员将从未有过性生活的雄性老鼠和有过性经验的雄性老鼠的大脑做了比较。

To find out whether an area known to be bigger in males was altered by having sex , the Saitama University researchers compared the brains of male rats who had never had sex before with their more experienced cage-mates .

Dr Tilly 's breakthrough came when he discovered that a former colleague , Yasushi Takai of Saitama Medical University in Japan , had in his freezer healthy ovarian tissue from 30 patients who had changed sex .
