There isn’t any evidence that additional testosterone from HRT causes any negative effects with PCOS if that’s something you’re worried about. Some studies have found a correlation between higher T and more symptoms, but none of those studies are looking at people intentionally raising their T levels to normal male range. One study even found that trans men with PCOS going on testosterone didn’t show any signs of the metabolic disturbances caused by PCOS: https://pubmed.ncbi.nlm.nih.gov/29624102/

It may mean you need a different dose than is typical depending on how your body responds to it, but that’s not unusual. A good GP or endocrinologist will be able to monitor your levels and adjust your dose accordingly.

I have PCOS and am on a normal dose of T. I had the same worries as you about messing with my hormones since it took years for them to stabilise!! But haven’t had any problems so far so I’m glad I didn’t delay starting any longer.

My endocrinologist also had no issues starting me on Testosterone. He wants me to get regular blood tests but that’s the same for all his patients.

I already had a bit of body hair and a bit of a moustache pre-T so timeline wise that is the only thing that seems to have happened quicker than normal (I’m on T 4 months now and already have to shave). I haven’t had any other outwardly noticeable changes except my voice dropping a little.

Generally pcos means that you eventually need to be on hormone treatment anyway, so the treatment might as well be masculine since your hormones already need to be changed. It’s different for everyone ofc but my endocronoligist says that my terrible hormones were like a blessing in disguise because it was hard to make it worse with the treatment lmao
