Premature ejaculation can be somewhat alleviated by taking Viagra, but it does not fundamentally solve the problem of premature ejaculation. For premature ejaculation accompanied by erectile dysfunction, taking Viagra can improve symptoms to some extent. However, for premature ejaculation caused by inflammation of the reproductive system, taking Viagra will not result in significant improvement. Therefore, whether premature ejaculation can be treated with Viagra should be determined based on different medical conditions.
