Whether myasthenia gravis affects coitus depends on the specific subtypes, the adult type of ocular myasthenia and mild generalized type usually do not affect coitus, while other types do.
Adult type of myasthenia gravis is divided into six types, of which the eye muscle type and mild generalized type have milder symptoms, mainly involving the extraocular muscles, eyes, face, etc. Other generalized symptoms are not obvious, and most of them can be taken care of by themselves, which generally will not affect cohabitation.
While several other types, such as moderate generalized type, acute severe type, delayed-onset severe type, myasthenia gravis, etc. will involve the limbs, and even slurred speech, difficulty in swallowing, weakness in chewing, muscle atrophy, which will affect coitus.
If diagnosed with myasthenia gravis, it should be actively treated to alleviate the adverse consequences of the disease, and if coitus is needed it should be promptly communicated with the doctor and handled according to the individual situation.
