Yes, methamphetamine use can affect sperm production and quality in men. Methamphetamine use can disrupt the normal hormonal balance in the body, leading to decreased testosterone levels and decreased sperm production. Methamphetamine use can also lead to oxidative stress, which can damage sperm DNA and reduce sperm quality.

Chronic methamphetamine use can also lead to other health problems that can affect fertility, such as weight loss, malnutrition, and chronic illness.

It is important to note that quitting methamphetamine use can help to improve fertility and sperm quality. However, it may take several months or more for sperm production to return to normal levels after quitting methamphetamine use.

If you are concerned about the impact of methamphetamine use on your fertility, it is recommended that you seek professional medical advice and support to address substance use disorders and any related health issues.
