There are several classes of medications available to improve fertility, but they require a prescription from a doctor. It is recommended to start taking a multivitamin with folic acid or folic acid alone, ideally three months before trying to conceive. In addition to medication, maintaining a healthy diet, managing stress, getting enough sleep, and exercising regularly can also help improve fertility. Other lifestyle changes such as reducing alcohol consumption, maintaining a healthy weight, quitting smoking, and having regular sexual intercourse can further increase your chances of conceiving.
