Will stopping use of recreational drugs (mdma, lsd, marijunana) lead to better sperm over time? will it get better if it is a bit off now?

Active drug : users cannot parent consistently, safely, or legally. Tobacco, excess alcohol, marijuana, cocaine & methamphetamine are a few of the drugs that impair fertility. Many impact the sperm; some, like marijuana & alcohol, also impact testosterone production. It can take up to a year in recovery for men to regain fertility from damaged sperm. See a urologist & an addiction medicine specialist.
