I'm currently in Europe. I won't be home until mid November. One of the articles was the effects of ultra low dose estrogen on women 58 -80. They all maintained bone density with no breast cancers noted. They were only using .125 dose. I'm taking .025. She thought that was too low. You might google it and find it. I'm afraid I can't remember the titles of the rest off the top of my head. There is another women on here maintaining her Forteo with hrt and mentioned some research. Perhaps you can find her. I'm sorry I don't rember her name.
Good luck
