Testosterone can increase iron absorption. I don’t think menstruation plays enough of a role reducing that given how little blood is lost for the average person. I’ve read about people who have been recommended that they donate blood to lower theirs. So to put some numbers up, most menstruation is between 25-30ml while a blood donation is about 500ml. You can donate blood a little under every two months
