>>12152957>>12152960Estrous synchrony, a phenomenon similar to menstrual synchrony,[77] has been reported in several other mammalian species.[78][79]
Menstrual or estrous synchrony has been reported in other species including Norway rats,[77] hamsters,[78] chimpanzees,[80] and Golden lion tamarins.[79] In non-human primates, the term may also refer to the degree of overlap of menstrual or estrous cycles, which is the overlap of estrous or menses of two or more females in a group due, for example, to seasonal breeding.[81]
However, as with early human studies on menstrual synchrony, non-human estrous synchrony studies also were criticized for methodological problems.[82][83][84]
Subsequent studies failed to find estrous synchrony in rats,[85] hamsters,[86] chimpanzees,[87][88] and Golden lion tamarins.[89]
