Male patients can still have a normal sex life after ligation surgery and can also ejaculate a small amount of thin tissue fluid after the sexual urge is finished. However, it does not contain any sperm, it is just a mixture of prostate fluid and water. The texture is thinner compared to semen, and there is no yellowish latex-like substance, and it does not produce liquefaction after being placed, nor will any viable sperm be found when a routine semen examination is done. When a male patient undergoes ligation surgery, both sides of the vas deferens are completely cut off, so the sperm produced in the testicles will not be matured by the epididymis and transported outside the body by the vas deferens, and will not cause the patient to conceive again. Therefore, after the ligation surgery, men still have normal sexual urge and can secrete some thin prostatic fluid, but there will be no sperm, no female pregnancy, no effect on sexual function, no change in the patient’s sexual urge, and no orgasm.
