Puneet Masson, MD, a urologist with Reproductive Medicine Associates, has seen a similar trend. “Normally, I would do about 7 to 10 vasectomy consults on a typical urology telemedicine day. Now I’m doing more than 20. Several patients, ranging from married couples with children to single childless men, have openly disclosed that the Dobbs decision encouraged them to be more proactive about their reproductive health,” he says.
The spotlight on male contraceptives has become so bright in post-Roe America that you can now find T-shirts with slogans like “Vasectomies Prevent Abortions,” and men undergoing the procedure can buy special vasectomy underwear with a pouch for a cold pack. But there is a lot of misinformation circulating about the procedure: Some men fear it will worsen sexual performance and prevent ejaculation, or mistakenly believe that a reversal later on down the line will be easy.
If you are considering a vasectomy, the top experts below have some answers about the reality of the procedure.
What Is a Vasectomy?
A urologist, or doctor specializing in the male reproductive system, will most likely carry out a vasectomy. However, some family doctors also have the training to perform a vasectomy.
Procedure
Be sure to turn up prepared with tight underwear or a jockstrap on the day of your procedure to support the scrotum and limit swelling after the surgery. You’ll also need to bathe or shower, washing your genitals thoroughly. Your surgical team may also ask you to shave the area. If they do, use a disposable razor and avoid hair removal products or electric razors.
During the procedure, the surgeon has two options for creating an opening in the scrotum:
- Incision Vasectomy They use a scalpel to cut a small hole in the scrotum.
- No-Scalpel Vasectomy They use a small instrument to create and spread open a small hole in the scrotum.
Questions to Ask When Considering A Vasectomy
As reversing a vasectomy is possible but not easy, speaking with your partner (if you have one) and your physician or urologist is vital to make sure it’s right for you. Here’s what to consider.
1. When Is a Vasectomy the Right Choice?
“This is really a personal decision, and one you shouldn’t just jump into. Some people say it’s not a good time to do it if you have a newborn because you’re sleep-deprived and you may later regret it,” says Sarah Vij, MD, a urologist with Cleveland Clinic in Avon, Ohio. “Others say that if you’re a younger childless male, you really shouldn’t do it, even if you feel pretty confident you don’t want kids. But I believe that any adult male who has the ability to make his own healthcare decisions can make a decision about contraception.”
2. Doesn’t It Make More Sense for My Partner to Deal With Birth Control, Since She Is the One Who Might Get Pregnant?
People often see contraception as the woman’s problem, but for a woman, effective birth control often entails birth control pills or an intrauterine device. “We always say that a vasectomy is an act of love. It’s wonderful to see so many men taking responsibility for the reproductive health of themselves and their families, and not asking their partner to bear the total burden,” says Dr. Masson.
3. Is a Vasectomy 100 Percent Effective?
Keep in mind when family planning that no birth control is totally fail-proof. “The failure rate, depending on the study you look at, is about 1 to 2 in 1,000. That’s over 99 percent effective, which is pretty comparable or exceeds pretty much all forms of birth control that we have,” says Dr. Vij.
4. Am I Sterile Immediately Following the Procedure?
No, a man has to ejaculate after the procedure in order for the sperm to clear, and the rate at which different patients clear varies tremendously. “Some guys might clear all the sperm in three ejaculations, and some might still be fertile after 30 or 40 ejaculations,” Vij explains. “I generally have patients get a semen test at three months, because the great majority of men will have cleared by then. A man should not consider himself sterile — and needs to continue using birth control — until he’s had confirmation from his doctor that he’s had clearance.”
5. I Get Squeamish Just Hearing About It. Does a Vasectomy Hurt?
You will be sore in the area for a few days afterward, but the discomfort can be managed with rest, nonsteroidal anti-inflammatory drugs, and an ice pack.
6. What Are the Risks of a Vasectomy?
The complication rate is less than 1 percent and includes bleeding, infection, inflammation, or ongoing pain, says Masson. “However, a small percentage of patients may have ongoing pain beyond just the recovery process. Should this happen, it’s important to regroup with your physician who performed the procedure.” He adds there is a 1 in 2,000 chance of recanalization, whereby the tubes reconnect, making the man fertile once again.
- Post-Vasectomy Pain Syndrome This may lead to long-term testicular pain, pain during ejaculation, and psychological distress, and its underlying cause is unclear. It affects between 1 and 2 percent of people after a vasectomy, but it is treatable.
- Sperm Granuloma This is a hard lump that can develop from the leakage of sperm from the snipped vas deferens. Sometimes, it can cause pain. However, the body almost always breaks it down and absorbs sperm granulomas, and they’re not dangerous. Pain relief can help, and compression shorts or jock straps can support the scrotum can reduce reduce symptoms.
- Scrotal Congestion This is a sense of pressure or an uncomfortable feeling in the testicles, the epididymis (the tube behind each testicle that stores and carries sperm), or the lower vas deferens. Scrotal congestion may develop between 2 and 12 weeks following a vasectomy, but it usually gets better over time.
7. Will a Vasectomy Affect My Sexual Performance? Will Sex Feel Different?
“It doesn’t impact sexual functioning at all,” Masson says. “Erections are going to be completely unaffected, and you will still have orgasms and ejaculations. The reason behind that is that only a small percentage of the ejaculate comes from the testicles. Most of it comes from the prostate and seminal vesicles,” he explains. “Thus, everything will still look and feel the same; just microscopically, there will be no sperm in the semen.”
8. If I Change My Mind Later, Can a Vasectomy Be Reversed?
9. Is There Any Other Way to Father a Child After a Vasectomy?
The Takeaway
- A vasectomy is a permanent form of male birth control that cuts and seals the vas deferens to prevent sperm from entering the semen.
- The procedure is low-risk, outpatient, and typically takes less than 15 minutes, with a local anesthetic minimizing discomfort.
- While the complication rate is low, potential risks include post-vasectomy pain syndrome, infection, and the very rare possibility of the tubes reconnecting.
- If you’re considering a vasectomy, it’s important to be confident that you’re sure about permanent contraception and discuss it with a healthcare provider, especially if you’re considering reversal later, as reversal attempts may not be fully effective and can be costly.
