I've been on tamoxifen about 4 months and to be honest I don't think it has made a difference in terms of libido. Mind you I think mine had dropped away anyway in the past year after all the BC traumas so I'm coming from a low starting point anyway (compared to a few years ago).I think Adean is right in that it's hard to put your finger on exactly what my be the cause of low libido but having a breast chopped off or even just chopped into doesn't exactly make you feel sexy, nor does being bald or feeling like crap because of chemo. I'm getting older too though, 47 now, so maybe my libido would have dropped away anyway at this age with menopause looming.Don't despair though, I think you can rev it up a bit by staying fit and healthy, looking after yourself, setting the mood etc. I'm sure you have your own ideas. Also from what I've read, I think tamoxifen is a lot less likely to kill off libido than the aromatase inhibitors. At least with tamoxifen we still get to retain some estrogen circulating in our bodies. Good luck, Janet.
