There may be risk of PID (fallopian tube
infection) in women with MG, but few if any
complications in men.
My advice is that if and when you have continuing symptoms, you return to a GUM clinic for personal evaluation. The professional staff at most UK GUM clinics know as much about this stuff as I do. Alternatively, if you prefer the private sector and live in or near London, consider a visit to the Freedom Health Clinic -- an excellent sexual health service center.
