2500IU twice a week is what fertility docs prescribe. I had a fertility doc try to prescribe that dose to me once.
The dose recommended by Merck, the manufacturer of Pregnyl, is all over the place:
"Selected cases of hypogonadotropic hypogonadism in males.
1. 500 to 1000 USP units 3 times a week for 3 weeks, followed by the same dose twice a week for 3weeks.
2. 4000 USP units 3 times weekly for 6 to 9 months, following which the dosage may be reduced to2000 USP units 3 times weekly for an additional 3 months."
