Hi mtjt, gosh if I knew a definite way to lower FSH I'd be doing it with mine at 17!!! Apparently it can fluctuate every month.
When I was researching it there were some ads from the states about natural supplements etc but I didn't venture into it too much. Some people have said acupuncture can help too.
However my specialist is happy for me to do another round with my current FSH as I responded well (8 embryos) last time round, so I'm not too concerned at this stage.
Sorry can't really be of help

it's just what our body decides to do!!
