Hi Karine, as someone who's had both ovaries removed I can testify to the much-needed difference testosterone replacement can make. But thinking about women with ovaries still intact postmenopause, there will presumably be individual differences in how our ovaries age, much as there are differences in other aspects of ageing? One friend my age has recently had a knee replaced, another a hip, whereas I can cycle, run, row etc without any problems in knees or hips - perhaps because I'm slight putting my joints under lesser load than heavier women, perhaps because I'm on HRT, perhaps nothing to do with either - maybe just the lottery of genetic predisposition. How do we know there are not similar differences in how much testosterone two women of the same age are producing (assuming they have not had levels tested), again maybe depending on genetics, other illnesses they may have suffered during their lifetime & so on? Women whose testosterone levels are optimal for their individual needs may feel & function vastly better than those whose levels are suboptimal, though both may still be within the reference (normal) range.
I think we need to be open to the possibility of differences in individual need for & response to all aspects of HRT. Some lucky women seem to feel & continue to function well enough without HRT during their postmenopause years, some of us find our lives wrecked, unrecognisable & unmanageable as a result of hormone decline leading up to & beyond menopause. If we can & choose to improve on that situation with HRT, much as we might gratefully accept a hip replacement or not say no to reading glasses at 45, it can be hugely empowering, enabling us to continue to live fulfilled, contented, productive lives, perhaps for decades longer than we otherwise would.
