Your wrong

- testosterone in a dose of only 100mg per week will bring sperm counts down to very minute amounts - pretty much null. Doses above that don't produce any further effects. Testosterone has been used as a male contraceptive but some do experience a rebound effect after discontinuation of high doses. But you need to wait anywhere from 3 months to a year... depending on your system. But 3 months is a minimum since that is the required time it takes for sperm to fully mature.
Be sure you are actually off AAS. While a man's use won't harm the fetus - it will keep you from returning to a normal sperm count. Don't try and continue using and run your wife through fertilty tests... the problem is most likely you if you are still running the gear...
