Are human females the only animals that get a menstrual cycle?
Ok, we need some clarification here. Menstrual cycles only occur in human beings and other female primates (apes). Human beings ARE animals. They are bipedal primates and the species is Homo sapiens. Homo sapiens fall under the kingdom Animalia. Ask any biologist. Also, dogs DON’T menstruate! Most mammals have estrus cycles and they often have bloody vaginal discharge but it’s when they ovulate and are fertile. Women also have an estrus cycle, but it occurs when they ovulate and are fertile. The menstrual period occurs 1-2 weeks later. This includes bloody discharge, and they are NOT fertile because women are actually shedding the uterine lining. It is possible to get pregnant while in the menstruation period, but only if there is enough uterine lining to let the fertilized egg implant itself. Long story short…humans are animals, only humans and other primates have a menstrual cycle. Other mammals have estrus cycles. Hope this helps!
