An external vacuum device can be used to pull blood into the penis. A special rubber band is then used to maintain the erection during intercourse. Premature ejaculation often goes away without treatment. But if it happens frequently, and it makes you or your partner unhappy, you may want to talk to your family doctor. There are several possible methods for delaying orgasm. Nutritional Supplements: nutritional supplements including the amino acid arginine, bioflavonoids, zinc, Vitamin C, Vitamin E, and flaxseed meal have been used to improve erectile function. In addition, certain ED patients with low levels of the hormone dehydroepiandrosterone (DHEA) showed improvement in erectile function after receiving supplemental doses of DHEA. However, because the long-term safety of DHEA is not known, most experts do not recommend its use. Hemoglobin A1c, serum chemistry studies, lipid profiles, and prostate-specific antigen levels should be obtained unless the patient has recently had these studies performed and the results are available.
