Avoid any activities that will raise the temperature of the scrotum, such as soaking in a hot tub or hot bath, wearing tight underwear or clothing, or using a laptop on your lap for extended periods of time. Heat can temporarily but significantly impair sperm production.
Aim to get 7–9 hours of quality sleep per night. Studies show that this is optimal for male fertility and hormone health.
Talk to a doctor to understand the impact of any prescription or over-the-counter medications taken regularly, such as testosterone replacement therapy or finasteride (Propecia).
