Anabolic steroids characteristically have a dreadful effect on male fertility and the effects can be very long-lasting. Firstly, you should stop taking them completely. Secondly, a sperm test will be able to assess the damage and perhaps give you some idea of your chances of natural pregnancy. If there is still a low sperm count after a year of not taking the drugs, there is no way of encouraging the testicles to recover. Some form of assisted conception might be possible, such as IVF/ICSI.
