FSHR and endometriosis: Many of the studies on extragonadal FSHR function were carried out only on women (endometrium, endometriosis, HUVECs etc.)(9, 10, 12, 17, 18) or female mice (osteoporosis, bone metabolism, or the FSH action on the myometrium muscle contractions etc.)(11, 13, 21, 22, 63) or cells derived from females (for example HUVECs) (9, 10, 12).
