Patient's question:
[Impotence and premature ejaculation, what medicine should be taken to treat it? How many courses of treatment are needed?]Doctor's answer:
Here is the English translation of the provided text, with line breaks preserved as instructed:Medications that can be used for erectile dysfunction include prostaglandin E1, papaverine, phentolamine, and other vasodilators. These drugs can be injected into the corpus cavernosum of the penis to induce erection through local vasodilation. Vitamin B12, A, C, and E may also play a certain role.
For patients with pernicious anemia combined with oligospermia, treatment with vitamin B12 not only increases red blood cell count but also improves semen quality, restoring fertility and achieving a "double blessing" effect. Foods rich in vitamin B12 include liver, dairy products, and fish. Vegetarians, who do not consume these foods, have significantly lower concentrations of vitamin B12 in their semen.
Both vitamin A and E can enhance libido, increase sperm production, and improve sperm motility. A deficiency in vitamin A can affect spermatogenesis in male animals, leading to degeneration of the epididymal epithelium, reduced testicular weight, shrunken seminal vesicles, and squamous metaplasia of the prostate. Foods rich in vitamin A include animal liver, milk, eggs, cod liver oil, corn, carrots, sweet potatoes, and tomatoes. The role of vitamin C is to reduce sperm aggregation, facilitating semen liquefaction. Fresh vegetables, fruits, and vegetable oils are very rich in vitamin C.
