There is no clear dietary supplement for premature ejaculation; food can only provide nutrition, not cure premature ejaculation. Premature ejaculation can affect the quality of sexual life and is a common cause of male infertility. Premature ejaculation can be treated with topical or oral medications. Topical medications are mainly local anesthetics such as lidocaine cream, oxybutynin cream or dacronine hydrochloride. Applied to the glans area about 15 minutes before sex, it can reduce glans sensitivity, prolong penile erection time and improve the quality of sex life. Oral medications such as dapoxetine hydrochloride, a selective pentazocine reuptake inhibitor, are taken 1-3 hours before sex. The drug may cause adverse reactions such as syncope and upright hypotension during treatment; it is contraindicated for people who are allergic to the drug, patients with mania or major depression, heart failure, and moderate-to-severe liver and kidney failure. Premature ejaculation patients should go to the hospital as soon as possible, after diagnosing the cause of the disease under the guidance of the doctor to actively carry out treatment.
