There are no over-the-counter products, supplements, or medications that can improve fertility. It is important to focus on non-pharmacological measures such as managing stress and getting enough quality sleep, following a balanced diet with plenty of fruits and vegetables, exercising moderately for at least 30 minutes a day, and avoiding smoking, vaping, or drinking alcohol. It is also important to remember that conceiving can take up to a year, even for healthy individuals. If you have been trying for over a year without success, it is recommended to seek medical evaluation.
