What is defined as a surgical cutting into the seminal vesicles?

The term that defines a surgical incision into the seminal vesicles is vesiculotomy. This procedure specifically involves cutting into the seminal vesicles, which are two glands located behind the bladder that store and produce a significant portion of the fluid that makes up semen. Vesiculotomy may be performed for various medical reasons, including the treatment of certain conditions affecting the seminal vesicles such as infections, cysts, or other abnormalities.

On the other hand, the other terms refer to different surgical procedures: vasectomy involves cutting the vas deferens to prevent sperm from entering the ejaculate; cystectomy refers to the surgical removal of the bladder or cysts; and prostatectomy is the surgical removal of the prostate gland, usually due to conditions like prostate cancer. Each of these procedures targets different anatomical structures and serves distinct purposes, which clearly distinguishes vesiculotomy as the correct answer in the context of surgery involving the seminal vesicles.
