Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest.

summary
Three men who volunteered as normal subjects were found to have abnormally high
levels of serum follicle-stimulating hormone (FSH) despite having normal seminal
fluid analyses and fertility. Two of the men had a history of previous orchitis, and one
had an atrophic testis. Serum luteinizing hormone and testosterone levels were
normal. These cases appear to represent compensated primary testicular disease, with
normal sperm counts and fertility maintained at the expense of chronically elevated
FSH levels. These results imply that in certain situations, the measurement of serum
FSH levels may be a more sensitive index of testicular disease than the performance of
seminal fluid analyses.
My own high FSH was due to low testosterone levels.
