Vasectomy: How it Works – Department of Urology

Introduction to Vasectomy:

Vasectomy is a permanent form of male sterilization that involves blocking the tubes that carry sperm from the testicles to the semen. It is a highly effective and long-term method of birth control, with a success rate of over 99%.

How Vasectomy Works?

During a vasectomy, the tubes that carry sperm from the testicles to the semen (vas deferens) are cut, tied, or sealed to prevent sperm from reaching the semen. The procedure does not affect hormone production or sexual function.

Types of Vasectomy:

There are two main types of vasectomy: conventional vasectomy and no-scalpel vasectomy (NSV). Conventional vasectomy involves making two small incisions in the scrotum, while NSV involves making a small puncture in the scrotum to access the vas deferens.

The Vasectomy Procedure:

Vasectomy is typically performed as an outpatient procedure using local anesthesia. The procedure takes approximately 30 minutes to an hour to complete.

Recovery and Aftercare following Vasectomy:

After the procedure, patients should rest and avoid heavy physical activity for a few days. Over-the-counter pain relievers can be used to manage any discomfort. Sexual activity can typically be resumed within a week, but other forms of contraception should still be used until a semen analysis confirms that the semen is sperm-free.

Risks and Considerations of Vasectomy:

Vasectomy is generally a safe and effective form of birth control, but like any medical procedure, it does come with some risks and considerations, including pain, bleeding, infection, and failure. Additionally, vasectomy does not protect against sexually transmitted infections (STIs) and should not be considered a form of STI prevention.

Alternatives to Vasectomy:

Other forms of birth control, such as male condoms, withdrawal method, female sterilization, intrauterine devices (IUDs), and hormonal methods, can also be used to prevent pregnancy.

Vasectomy and Sexual Function:

Vasectomy does not affect hormone production or sexual function, including libido, erectile function, and ejaculation.

Cost of Vasectomy:

The cost of vasectomy can vary depending on factors such as location, insurance coverage, and the type of procedure. In general, vasectomy is more cost-effective in the long-term compared to other forms of birth control.


Is Vasectomy Right for You? Vasectomy is a highly effective and long-term form of birth control that can be an excellent option for men who have completed their families or who do not wish to have children in the future. However, it is important to discuss the risks and benefits of vasectomy with a healthcare provider and to carefully consider one’s personal circumstances before making a decision about male sterilization.
