I am suffering from PFS. I have taken many blood tests over the years and one value is striking: My FSH is always either too high or right at the end of the range. What could be the reason. Perhaps this has to do with my PFS. My LH is always ok (in the middle of the range). My Testosterone levels are also in the middle of the range (e.g. 18,1 nmol/l - range: 5,5-25,2 mol/l). How could help?
