Free Sperm Donor Sites: What to Check First

A free sperm donor site is free in one narrow sense: nobody charges you for the sperm. Everything a sperm bank does around that sperm still costs money, and on a free donor site it either gets skipped or gets paid for by you. Testing, storage, legal work and the clinic are the actual bill.

That is the honest version of the tradeoff, and the rest of this article works through the individual pieces with US law and published US prices. One thing to state plainly at the start: sperm-donation.com is a matching platform. People create profiles, search, and message each other, and that is the whole product. We do not handle, store, test, or ship anything biological, we are not a clinic or a sperm bank, we do not verify identity or health, and we do not give legal or medical advice. The checks, and the decisions, stay with you.

What does “free” actually mean on a free sperm donor site?

It means no purchase price for the sperm itself. It does not mean no cost, and it does not mean the safeguards a sperm bank sells are included somewhere else.

When you buy a vial from a cryobank, the price covers a screened donor, laboratory testing, freezing, a six month quarantine, a stored record of who he is, and a shipping chain. California Cryobank’s published pricing, checked in August 2026, runs from $897 to $2,397 per vial. Seattle Sperm Bank lists IUI and ICI vials at $1,695 per unit, and $1,395 for its A.R.T. preparations, with standard two business day shipping at $180 and overnight at $280, all from its own 2026 price page.

On a free donor site none of that is bundled. The man is offering the material and nothing else. Whether testing happens, whether anything is frozen, whether a record exists, and whether the state treats him as a father are open questions that the word “free” does not answer.

Which US sites do people use, and what are they?

People searching for a free sperm donor in the US generally land in three places: open matching platforms with public profiles, private Facebook groups, and known donor registries that predate the current platforms. All three are places to find a person, and none of them is a medical or legal service.

The research picture is now reasonably clear. A 2024 study published in Frontiers in Reproductive Health, based on narrative interviews with donors and recipients in online sperm donation communities, describes recipients raising concerns about donor dishonesty, online abuse, and the absence of support from the connection sites themselves when something went wrong. That is a description of what the researchers heard, and it matches what the sites’ own terms say about their role.

Facebook groups behave differently from platforms, mostly in how they handle history and moderation, and that comparison is covered in Facebook sperm donor groups vs matching platforms. Paid platforms are not automatically more careful, which is why the terms of one of the largest, reviewed in our CoParents.com review, are worth reading before assuming a subscription buys verification.

What does a free sperm donor site verify?

In almost all cases, nothing that matters medically. Read the terms of service of any site you use and look specifically for the words “verify”, “screen”, and “background check”, because that section is where the site tells you what it is not doing.

A profile can display an age, a height, an education level, a photograph, a claimed number of previous donations, and a claim about testing. None of that is confirmed by anyone. There is no national registry of private donations in the US, no legal cap on how many families one man can help, and no requirement that he disclose a genetic condition he knows about.

This is the part where people substitute the feeling of a polished interface for actual checking. A well designed profile page and a responsive messaging system tell you the site has good engineers, and nothing about the man on the other end. What produces evidence is a dated laboratory report from a named laboratory with his name on it, which he obtains and shows you.

What does the FDA require when no clinic is involved?

Federal tissue rules apply to establishments such as sperm banks and clinics. They do not reach two private individuals arranging a donation between themselves, which means that in a fully private arrangement there is no federal testing requirement and no record that anyone was tested.

The specific provision people misread is 21 CFR 1271.90(a)(2), which exempts reproductive cells donated by a sexually intimate partner of the recipient from donor eligibility determination, screening and testing. A known donor who is not a sexually intimate partner falls outside that exemption, so when a bank or clinic handles his samples, the establishment must screen and test him. Skipping the clinic does not transfer that protection to you. It removes it.

That is the trade the word “free” is really describing. The panel a bank runs covers HIV-1 and HIV-2, hepatitis B surface antigen, hepatitis C antibody, syphilis, chlamydia, gonorrhea, HTLV-I and HTLV-II, and CMV, repeated at six month intervals under FDA guidance. What each of those tests catches, and what a carrier screen adds on top, is set out in sperm donor screening: what people test for.

Why do banks quarantine samples for six months?

Because a blood test taken on the day of donation cannot rule out an infection acquired shortly before it. Seattle Sperm Bank states on its own directed donor page that the FDA, the CDC, the American Association of Tissue Banks and ASRM all recommend a six month quarantine of donor semen samples followed by repeat blood testing, and that the quarantine covers the window between HIV infection and the point at which HIV antibodies become detectable.

Fresh donation on a free donor site has no quarantine by definition, since nothing is frozen. A test result dated two weeks ago describes the donor two weeks ago. People decide to accept that risk all the time, and the decision is a real one only if it is made knowingly rather than by default.

Banks do allow the quarantine to be waived. Seattle Sperm Bank reclassifies a directed donor as a “known donor” when the recipient waives quarantine in writing after being advised of the risks, and notes on the same page that some clinics will not work with samples that were never quarantined.

Does a written agreement make him a non-parent?

It depends entirely on your state, and the honest answer for the US is that there is no national rule. Some states treat a written donor agreement as decisive, some make the donor’s non-parent status conditional on other requirements, and some have no assisted reproduction statute that covers an unmarried recipient at all.

The 2017 Uniform Parentage Act is the model that removes a donor’s parental status where he did not intend to be a parent, and it recognizes intended parents regardless of marital status or genetic tie. As of reporting by the National Center for Lesbian Rights, nine states had enacted it: California, Colorado, Connecticut, Maine, Massachusetts, Oregon, Rhode Island, Vermont and Washington. In a state that has not, the older statute or case law governs, and those vary widely. The Movement Advancement Project maintains current maps of parental recognition by state.

A written agreement is still worth having in every state, because it records what two people agreed about contact, future children, and money, and because a court that considers intent will look for evidence of it. What it cannot do is override a statute that makes the donor a legal father.

Which states tie the donor’s protection to a physician?

Several states protect a sperm donor from parentage only when the semen was provided to a licensed physician for insemination. Kansas is the clearest example and the reason this issue is widely known.

In the Kansas case involving William Marotta, a man who responded to a Craigslist ad and signed documents waiving parental rights was ordered to pay child support, because the parties had not involved a licensed physician as K.S.A. 23-2208 requires. The court’s reasoning was that the parties’ own designation of him as a donor could not substitute for the statutory requirement. Whatever the parties believed they had settled in writing, the statute decided it.

New Jersey’s statute at N.J.S.A. 9:17-44 similarly frames the donor’s non-parent status around semen provided to a licensed physician, physician assistant or advanced practice nurse. Idaho and Montana have statutes written around physician involvement as well. These are examples rather than a complete list, statutes change, and the only reliable answer for your own situation comes from a family law attorney licensed in your state.

What does the free route actually cost?

Between roughly $400 and $3,000 in most private arrangements before any clinic treatment, depending on how much testing you ask for, whether you use an attorney, and whether you involve a bank at any point. The sperm is the only free part.

These are the items that come up. In the arrangements people describe, the recipient usually pays for all of them, and who covers travel is the one point that varies a lot.

Cost itemWhat it covers
Donor infectious disease panelHIV, hepatitis B and C, syphilis, chlamydia, gonorrhea
Carrier screening, optionalRecessive genetic conditions
Semen analysisCount, motility, survival after freezing
Attorney reviewThe donor agreement and state specific parentage advice
TravelThe donor’s travel to each attempt
Clinic IUI, if usedInsemination performed by a clinician

The alternative that people rarely price out is a directed donor program at a sperm bank, which keeps the person you chose and buys back the laboratory process. Seattle Sperm Bank’s published route for a directed donor includes a semen analysis and test thaw appointment, a medical social questionnaire, a physical exam including a genital exam, infectious disease blood and urine testing, a collection period, storage, and a six month exit blood draw before samples are released. The bank publishes its own fee schedule for that program, and other banks publish theirs. The comparison between that route and a fully private one is worked through in sperm bank or known donor.

How many children does he already have?

Nobody in the US can answer that for you, and no register exists that would let you check. ASRM’s gamete and embryo donation guidance suggests that in a population of 800,000, limiting one donor to no more than 25 births would avoid a significant increase in the risk of inadvertent consanguineous conception. That is professional guidance for clinics, and it does not bind a private donor at all.

On free donor sites the number is whatever he tells you. Some men are open about it, some understate it, and some have genuinely lost count across several years and several platforms. Researchers looking at online sperm donation communities have described prolific donors as a recognized feature of these spaces rather than an anomaly.

Ask the question directly, ask how many were fresh donations and how many went through a bank, and ask whether he is willing to be identifiable to the child later. The reasoning behind why the number matters to the child rather than to you is in donor siblings: how many is too many, and the related question of what you will eventually tell your child is covered in telling a child they are donor conceived.

What to check first, in order

Six things, in this order, because each one saves effort on the next.

  1. Your own state’s parentage law. Find out whether a written agreement carries weight where you live and whether a physician must be involved. This determines whether the rest of the route is viable at all, so it belongs before you contact anyone.
  2. The site’s terms of service. Read what it says about verification and about its own liability. A site that says plainly that it verifies nothing is being accurate, and now you know what you are responsible for.
  3. His testing, in writing. A dated report from a named laboratory, in his name, covering the standard panel. Recent means within the last few weeks, and the timing question is separate from the result.
  4. His contact expectations. Whether he wants to meet the child, at what age, how often, and what he expects to be told. Two people who each assume their own answer will discover the mismatch years later.
  5. His answer on future identifiability. Donor conceived people increasingly find genetic relatives through consumer DNA testing regardless of what anyone agreed. A donor who understands this and accepts it is a different proposition from one who assumes permanent anonymity.
  6. An attorney in your state. Before conception, not after. Even where the outcome is uncertain, an attorney can tell you what the uncertainty consists of.

Which warning signs come up repeatedly?

Four patterns recur often enough on free donor sites to be worth naming: pressure on timing, deflection about testing, an offer of so called natural insemination, and a request for money framed as expenses.

Pressure on timing usually sounds like urgency about your fertile window combined with reluctance to wait for a test result. The fertile window recurs every cycle, and the guide on ovulation timing covers why the calendar is less of an emergency than it feels. Deflection about testing is information in itself, because the request is ordinary and banks treat it as routine, so a man who treats it as an insult has told you how a future conversation about a child will go.

Some men on open platforms and in groups offer to conceive through intercourse, described as natural insemination. This is a pattern people report encountering, and it belongs here as a risk to recognize rather than as a method alongside the others. It removes every safeguard that testing and quarantine exist to provide, and it changes the factual picture around consent and parentage in ways no agreement addresses. Anyone presenting it as more effective is making a claim with nothing behind it.

Requests for money on a free donor site deserve a plain answer. Paying a sperm donor is lawful in the US and cryobanks pay their catalog donors, so money is not by itself a problem. What matters is that any payment is discussed with the attorney who reviews the rest of the agreement, because how a payment is characterized can matter to the parentage question in some states, and because an escalating request early in a conversation is a recognizable pattern. How the first conversation is best handled is set out in meeting a sperm donor for the first time.

Where does a matching platform fit, and where does it not?

A platform is a place to find people and to hold the early conversations in one system. It gives structure to a search that otherwise runs across scattered group posts, and it keeps a record of what was said.

What it does not do is anything medical, legal, or biological. We do not screen health, verify identity, run background checks, hold samples, arrange shipping, or draft agreements. The parts that decide how this turns out, meaning the testing, the attorney, and the clinic if you use one, are arranged by you with professionals who carry the responsibility for them. Where the search itself is concerned, the full US picture of where people look is in how to find a known sperm donor in the US.

Frequently asked questions

Is it legal to use a free sperm donor site in the US?

Yes. Federal tissue rules under 21 CFR Part 1271 regulate establishments such as sperm banks and clinics rather than private individuals, and no federal rule prohibits two people from arranging a donation between themselves. The separate question of whether the donor is a legal parent is decided by state law, and in some states, such as Kansas under K.S.A. 23-2208, the donor's protection depends on a licensed physician performing the insemination.

Does a free sperm donor have to be tested?

Only if a bank or clinic is involved. Under 21 CFR 1271.90(a)(2) the exemption from screening and testing covers a sexually intimate partner of the recipient, so a known donor who is not that partner must be screened and tested when an establishment handles his samples. In a fully private arrangement no federal testing requirement applies, which means any testing happens because the two people involved arrange it.

How much does the free route cost in total?

The sperm is free and the surrounding costs are not. In most private US arrangements the recipient pays for the donor's infectious disease panel, optionally a carrier screen and a semen analysis, an attorney to review the agreement, and any clinic treatment. For comparison, a purchased vial ranges from $897 to $2,397 at California Cryobank and $1,395 to $1,695 at Seattle Sperm Bank, both checked in August 2026, before shipping and clinic fees.

Can a free sperm donor be made to pay child support?

In some states, yes. The Kansas case involving William Marotta ended with a donor ordered to pay child support because the parties had not involved a licensed physician as the Kansas Parentage Act requires, even though he had signed documents waiving parental rights. Other states treat a written agreement as decisive, and a number have enacted the 2017 Uniform Parentage Act, which removes parental status from a donor who did not intend to parent. A family law attorney in your state is the only reliable source for your own case.

How many children can one private donor father in the US?

There is no legal limit and no national register. ASRM's gamete and embryo donation guidance suggests that in a population of 800,000, no more than 25 births from one donor would avoid a significant increase in the risk of inadvertent consanguineous conception, and that guidance applies to clinics rather than to private arrangements. On a free donor site the only available figure is what the donor states.

Are paid platforms safer than free ones?

A subscription does not buy verification. Paid and free platforms alike describe themselves in their terms as places where members contact each other, and the terms are where each site sets out what it does not check. The practical difference tends to be moderation, message history and search tools rather than any assurance about the people in the profiles.

The short version

A free sperm donor site removes the vial price and leaves everything else in place. The testing, the quarantine decision, the parentage question and the clinic are still there, and they are now yours to arrange, pay for, or knowingly skip.

Start with your own state’s law rather than with profiles, because whether a written agreement carries weight and whether a physician must perform the insemination changes the entire route. Ask for dated laboratory results from a named laboratory and treat the date as seriously as the result. Talk about contact expectations until each of you can repeat the other’s answer, and put an attorney in the process before conception rather than after.

If you want the laboratory process without the catalog, a directed donor program at a sperm bank keeps the person you chose and adds screening, quarantine and freezing at a published price. If you go fully private, those safeguards exist only to the extent you build them yourself.

We are a place where people find each other. The guides cover what stays the same wherever you live, including how home insemination works and what donor screening covers. You can create a profile at your own pace, read about who we are, or get in touch if anything here needs correcting.
