Epididymitis is a common disease among young men, mostly caused by bacterial invasion of the epididymis, and can be divided into acute and chronic phases. The epididymis is a place for storing sperm and further maturation of sperm. Inflammation of the epididymis does not affect sexual function, but it has an effect on sperm. Acute epididymitis mostly starts rapidly with severe pain and temporarily inhibits sexual function, but sexual function will be restored after it is healed. Chronic epididymitis has almost no effect on sexual function. However, because the epididymis becomes hardened by long-term inflammation, when the ejaculation climax is reached during sex, the epididymis and vas deferens contract and pain occurs, and sometimes the pain lasts for a while after intercourse. Therefore, there is interference with the quality of sexual life. Do not have sexual intercourse when you have acute epididymitis. Because the epididymis is in the inflammatory state of congestion and edema, sex will aggravate the swelling of the epididymis and is not conducive to the inflammation subsiding. Sexual life should be started gradually only after it has been cured. In the beginning, the number of intercourse should not be too frequent. Epididymitis is often prone to recurrence because the bacteria in the slender and tortuous epididymal duct are not easily eliminated completely. If you have too much intercourse, the bacteria will resurface and develop again, but you should not abstain from sex for fear of recurrence. If you don’t have sex for a long time, sperm will be stagnant in the epididymis, making the epididymis in a full state and causing congestion. In short, after getting epididymitis, no matter acute or chronic, you must treat it thoroughly and have sex moderately, which is good for preventing recurrence.
