1st rodent with human-like menstrual cycle found
Researchers at the Monash University in Australia claim to have found a rodent, the spiny mouse (Acomys cahirinus), that has a human-like menstruation cycle. For the research, the team tracked 14 female mice and found that the mice, with a ratio similar to humans, had a nine-day menstrual cycle and spent three of the nine days shedding the uterine lining.
