I'm not sure how correct I am, but I thought that it was strongly advised not to stop T if you've had a hysto, or if you are to stop T to take estrogen again as osteoporosis is more likely if there is a very small amount/no hormones in your body. I think that's why osteoporosis is more common in post-menopausal women as they have lowered amounts of hormones and why hormone blockers aren't prescribed long term. I'm not sure how accurate I am, and it would be possible to stop T after a hysto but really not advised, especially for long periods of time.
