After a man’s ligation surgery, the sperm produced by the testicles will usually be broken down and absorbed after entering the epididymis without any adverse effects. If the sperm cannot be completely broken down and absorbed in the epididymis, it may stagnate in the epididymis and form epididymal semen cysts. If the epididymal semen cysts are relatively small and do not have any uncomfortable symptoms, they do not require special treatment. If the epididymal semen cyst is large or is complicated by infection, causing painful enlargement, or even affecting the testicles, epididymectomy can be considered. In men, ligation surgery only blocks the passage for sperm discharge and does not affect sperm production, so if you need to have children again after ligation, you can consider vasectomy.
