Very few other animals do this:

"The endometrium, which lines the uterus, is a distinct tissue that is capable of monthly remodeling, shedding, and regeneration. Other than humans, very few species exhibit a similar menstrual cycle. Given the importance of the endometrium to fertility and women's health, Wang et al. undertook single-cell transcriptomic characterization of the endometrium across the menstrual cycle from 19 healthy donors. The authors defined four phases across the cycle and characterized the window of implantation and accompanying changes in gene expression in the epithelia. They also discovered the presence of ciliated epithelium and characterized how these cells and six other cell types change over the course of the cycle. These high-resolution data provide important insights into female physiology and have numerous applications in fertility and endometrial biology."
