How does a Vasectomy Work?
A vasectomy involves the cutting of the vas deferens in order to prevent sperm from entering the ejaculate. The vas deferens are two tubes that carry sperm from the testicle to glands at the base of the bladder called the seminal vesicles and the prostate gland (see diagram). It is here that sperm mixes with seminal fluid (the secretions of these glands) to form the ejaculate. A vasectomy is usually performed through small incisions in the front of the scrotum.
The production of the male hormone testosterone is not effected by this procedure.and neither is the ability to perform sexually. What are different types of techniques used for Vasectomy procedures?
There are several types of vasectomy techniques and there are differences with each of these procedures. Many men are now considering the type of vasectomy technique used when considering a service provider.
No Scalpel Vasectomy (NSV)
- Routinely, the “no scalpel” technique involves splitting the skin with forceps to access the vas tubes. (The term “no scalpel” means that a scalpel is not used to cut the skin, but that forceps are used to tear the skin open instead
- These forceps are sharp instruments that do pierce the skin.
- Both ends of the tubes are then either cut and tied or cauterized to prevent the movement of sperm.
- Sperm production continues and with the vas sealed, the sperm build up in the tubes and clog the system over a period of time.
Open Ended Vasectomy
- The open-ended technique involves a fine cut made into the area to access the vas tubes.
- The tubes are cut, but only the testicular end is left opened and unsealed, with both ends of the tubes separated by layers of tissue within the scrotal sac with fine suturing.
- As a result, the sperm do not build up within the vas, but flow as normal and are usually absorbed by the body under the skin.
- This prevents the build up of sperm and the associated congestion, with a lower incidence of postoperative pain and offers a potentially better vasectomy reversal rate.
