  • You are testing your vasectomy to ensure the procedure was successful

Don't roll the dice on your fertility.
Test your vasectomy with Fellow.

While most vasectomies are sucessful, they are not 100% guaranteed. That's why patients need to use another form of birth control to avoid pregnancy until vasectomy test results show zero sperm in a sample. In some cases, achieving zero sperm takes weeks or months longer than expected, and in rare cases, a second vasectomy is required. Testing is the only way to ensure you will not conceive a child.

Get peace of mind by testing conveniently at home.

How to test the success of your vasectomy from home:

1. Wait 12 weeks and clear out your system.

The American Urological Association recommends ejaculating at least 20-30 times during a 12 week period following your vasectomy. During this time you and your partner should use other forms of birth control because there may be lingering sperm cells in your reproductive tract.

2. Conveniently test at home.

With a Fellow Vasectomy Test you can produce a sample at home and mail it back (shipping is already included). We'll analyze your sample in our CLIA-certified lab to look for any sperm.

3. Clinically validated testing.

We'll email you a link to a secure webpage with your easy-to-understand results. If your healthcare provider recommended this test, we can send them a copy of your results as well.

4. Repeat if necessary.

If your results indicate you have sperm in your sample, or if your doctor requires two tests to deem a vasectomy successful, test again conveniently at home. Some doctors advise to get tested a year after your procedure to ensure that your vas deferens (what was cut during the vasectomy) did not repair itself.

About the Fellow Vasectomy Test

No vasectomy is complete until your semen has been checked for the presence of sperm. Why? About 1 in every 1,000 vasectomies isn’t successful. This can happen for a number of reasons, but all you really care about is making sure that 1 in 1,000 isn’t you. The Fellow Vasectomy Test looks for the presence of sperm in your semen, so that you can move on with confidence that you are not risking an unwanted pregnancy. Until you’ve tested your vasectomy, you should continue using another form of contraception.
Yes! This test is perfect for you. If you are ordering from our website, just make sure to select the Vasectomy Test (not the Semen Analysis). When you register your sample, you will also be asked to confirm why you are testing. The Fellow Vasectomy Test allows you to produce a semen sample at home and ship it back using our discreet mailer and prepaid shipping label. Once our lab receives your sample, we will check to see if there are any sperm in your semen.
After you’ve produced your sample, you’ll follow the instructions to mark your collection cup and pack and seal your kit. Then, you'll drop your kit off at a UPS Store (not a Drop Box or Access Point). Your kit will ship to us via UPS Ground (the label is already on the box) and it should reach our lab in 4–5 business days. You’ll receive your results 1–2 business days after that.
Fellow recommends that you wait 12 weeks between your vasectomy and when you use your Vasectomy Test kit. We also recommend that you ejaculate at least 20 times. Sperm can hang out in your reproductive tract for weeks (amazing, right?), and ejaculating helps flush them out. Your healthcare provider may recommend other things to do during recovery and before you test, so make sure to follow that guidance as well. (Please note: Test timing and requirements are different for customers using our Semen Analysis.)
Results are typically returned 5–7 business days after you ship your sample. Your Vasectomy Test kit will ship back to us via UPS Ground, which usually takes 3–5 business days. Our lab will process your sample within 1.5 business days. When you results are approved, we'll send you a secure link via email to view your report in your Fellow account. Because we test your semen until we see no sperm at all, the health of your sperm during this travel time doesn’t really matter. There should not be any sperm—living or dead—in your semen following a successful vasectomy.
Thousands of providers and patients choose Fellow because the old way of producing a sample for vasectomy testing just doesn’t make much sense. Having to make an appointment and then visit a lab or clinic to masturbate in a strange sample collection room is inconvenient, uncomfortable, and unnecessary. Dropping off a semen sample at your provider’s front desk is a little easier, but nobody wants to hand over a cup of their own semen to a stranger at the front of a crowded waiting room. With Fellow, you get clinically valid results while being able to produce your semen sample from the comfort of home, like you’re used to. We also send helpful reminders and provide fast customer support should you need any help.
Yes, but the only part of the kit that expires is the preservation solution (which helps keep your semen sample stable during transit). The preservation solution expires on the date listed on the sticker on the outside of the box. If this date has passed or is coming up soon, simply reach out to us at support@meetfellow.com. We’ll send you a new vial of preservation solution, free of charge.
If the preservation solution in your kit has expired (or is nearing expiration), please do not send back your kit. Instead, reach out to us at support@meetfellow.com. We'll send you a new vial, free of charge.
We are happy to provide a refund up until your kit ships out to you. After your Vasectomy kit ships, we generally cannot provide refunds or accommodate returns. If you have questions or concerns, please reach out to support@meetfellow.com.
At this time, all Fellow kits must be paid for out-of-pocket. If you have an HSA or FSA account, you may be able to seek reimbursement from your plan. The first step would be to check with your plan provider. If they approve the expense, you can pay for your kit with your personal credit card and then submit a receipt for reimbursement. If you need a detailed receipt, let us know at support@meetfellow.com. We can provide one to you as soon as you have your results.
No. These tests are different, because they have different goals. The Vasectomy Test looks for the presence of sperm. That’s it. The Fellow Semen Analysis, on the other hand, looks at how many sperm are in a sample, and how healthy they are (based on a number of different metrics). This test is more complicated, and therefore slightly more expensive. The Vasectomy Test should only be purchased if you are looking to test the success of your vasectomy. If you have additional questions about which test is right for you, please shoot us an email at support@meetfellow.com.

Producing your sample

At this time, the only way to produce a sample for testing is through masturbation without lubrication. We can't provide a reliable analysis on samples that were generated using any other method.
No. Most lubricants contain spermicides (chemicals that kill sperm), which would lead to inaccurate test results. Saliva and lotion are also a no-go, because they introduce bacteria into your semen sample, which makes it so we can’t test your semen. If we see bacterial blooms in your sample, you will have to test again. We get it: you probably don’t want to masturbate without lubricant. If there were any way around this requirement we would be thrilled. Unfortunately, there’s not. We know from years of experience that customers who use lubricant are highly likely to have their samples rejected, and to have to test again.
That depends on what kind of test you are using. If you are using our Vasectomy Test, you should wait 12 weeks after your vasectomy procedure, and make sure to ejaculate at least 20 times before testing. Then, produce your sample and drop it off at a UPS Store any day of the week. It will ship via UPS Ground, and you should have results back in 5–7 business days. If you are using our Semen Analysis kit (with or without opting for cryopreservation), you should not ejaculate for 2 days (don’t wait more than 5 days), and produce your sample on a Monday, Tuesday, Wednesday, or Thursday morning. This is because it’s crucial that your semen sample reaches our lab via UPS overnight shipping. If you send your sample on a Friday, Saturday, or Sunday, it won’t reach us quickly enough, our lab will not be able to provide you with results, and you will have to test again.
Do your best. We will let you know if our lab isn't able to process your sample due to insufficient volume. Experience has shown us that many samples are low volume because the person providing the sample did not get all their semen into the collection cup, so aim carefully! For some men, increasing arousal time can make a big difference in semen volume. Decreasing stress can also help, so try to get comfortable and relax before you use your test kit. If you have concerns about your ejaculate volume, you should consider talking to your doctor.
Illness can impact your sample and compromise your results, so it’s best to wait until you're feeling better. If you've had a fever recently, wait until your body has returned to its normal temperature for at least a week. If you’re on prescription medication, we recommend checking with your healthcare provider to get their opinion on whether that medication might impact your semen or sperm health.
Drop us a line at support@meetfellow.com and we'll figure out how to fix your issue. Don't be shy, we've heard it all before.

About Fellow

Fellow makes mail-in semen analysis kits that allow you to asses your sperm health and fertility, preserve your sperm for the future, or check to see that your vasectomy worked. In the past, getting a semen analysis meant making an appointment at a clinic or lab and producing a sample (by masturbating) while staff and other patients are right outside the door. With Fellow, you produce your sample at home, and get clinical-grade test results without the awkwardness or hassle. If you like convenience, comfort, and results that are just as accurate as traditional, in-person labs, Fellow might be for you.
This is a great question, but it’s not the right question. Laboratory tests like ours are never “approved” by the FDA. Laboratory testing is regulated according to what’s called the Clinical Laboratory Improvement Amendments, or CLIA (pronounced “klee-yuh”). Fellow’s lab is CLIA-certified (CLIA Number: 05D2177822), which means we meet all federal requirements for providing doctors and patients with semen analysis results that can be used to make healthcare decisions. CLIA compliance is monitored by three federal agencies: The Food and Drug Administration (FDA), Center for Medicaid Services (CMS), and the Centers for Disease Control and Prevention (CDC). Each agency has a unique role in assuring quality laboratory testing. At Fellow, we run our own dedicated, CLIA-certified laboratory. Operating our own lab allows us to ensure that every test is done to the same exacting quality standards, so you get results that you and your healthcare provider can use to make important decisions about your fertility. Our lab is also COLA-accredited. COLA (the Commission on Office Laboratory Accreditation) is a private, physician-directed non-profit organization that helps labs meet the highest standards for quality and operate in compliance with federal and state regulatory requirements.
Fellow takes your privacy very seriously. Your semen analysis kit will arrive in a discreet cardboard shipping box. Nobody looking at it will know what’s inside, unless they closely inspect the return address and have used Fellow themselves in the past. If that’s the case, expect a fist bump. Congratulations, you’ve made a friend. The return shipping box is discreet as well, with no mention of semen analysis on the outside, so you can feel comfortable dropping it off at UPS. Our lab staff processes your sample using barcode numbers and other information that does not identify you personally. Our lab also destroys your sample after processing it, so you can rest assured that it will NEVER be sold, saved, or used for insemination. Finally, your results are stored and delivered to you via our secure platform.
Yes! When you register your kit, you can input your provider’s clinic information. We will send results to them at the same time we send them to you.
