Is there a proven product available at the pharmacy that increases fertility?

There are no over-the-counter medications or dietary supplements that have been proven to increase fertility in men or women. However, making certain lifestyle changes can have a positive impact on fertility. These changes include quitting smoking, maintaining a healthy weight, reducing intense physical activity, limiting alcohol and caffeine intake, managing stress, and having regular sexual intercourse every 2 to 3 days. These changes promote a healthy lifestyle and can aid in conception and overall health.
