Fertility and finasteride in men

If my sperm count is reduced, does it go back to normal if you stop the drug to have a child?

If you have a fertility problem related to your sperm count from finasteride, you can expect that it might take months to return to normal. In the following publication: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3205531/, the authors state: “A patient on finasteride (1 mg) for 1 year, diagnosed with oligospermia (impaired spermatogenesis) 5 years earlier, was found to have increased semen volume immediately after cessation of finasteride and his sperm concentration improved to more than 10 × 106/ml about 4 months later.” You should read more of this publication.
