In page Prostatectomy:

"

Following a prostatectomy, patients will not be able to ejaculate semen due to the nature of the procedure, resulting in the permanent necessity of assisted reproductive techniques in case of desires of future fertility.[3] Preservation of normal ejaculation is possible after TUR prostatectomy, open or laser enucleation of adenoma and laser vaporisation of prostate. However, retrograde ejaculation is a common problem. Preservation of ejaculation is the aim of some new techniques.[4] Once the prostate and vesicles are removed, even if partial erection is achieved, ejaculation is a very different experience, with little of the compulsive release that is common to ejaculation with those organs intact.
