Yes. And No.

This is complicated.

I had to have an emergency partial hysterectomy a year before my MG was diagnosed.

Doc left ovaries. But I did not have the "cycle" anymore. So I can't say yes or not definitively.

A couple of years after MG diagnosis, gyn said I needed to take estrogen supplements to help with estrogen.

However, when I started on oral estrogen supplemention - my MG was greatly exacerbated. Not to point of crisis. I had to stop taking oral estrogen.


Here is a little PubMed statement about menstrual cycle and myasthenia gravis:
