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, they 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 need special treatment. If the epididymal seminal cyst is large or complicated by infection, causing pain and enlargement, or even affecting the testicles, epididymectomy can be considered. Men’s ligation surgery only blocks the channel for sperm discharge and does not affect sperm production, so if you need to have another child after ligation surgery, you can consider vasectomy.
