Donating sperm is a multi-step process that takes several weeks from your first application to your first paid donation. It involves an application, an initial sample evaluation, extensive medical and genetic screening, a background check, a psychological evaluation, and then ongoing visits to provide samples. Most sperm banks accept men between 18 and 39, and the acceptance rate is low: only about 1% of applicants at some banks make it through the full screening process.
The Application and First Visit
The process starts with an online application covering basic information about your health, education, and background. If the bank is interested, they’ll ask you to come in and provide an initial semen sample. You won’t be paid for this first sample. The lab uses it to evaluate three things: your sperm count, how well the sperm move (motility), and whether the sperm appear structurally normal (morphology).
Sperm banks set their thresholds higher than what a fertility clinic considers “normal” for the average man. A typical clinical benchmark is 20 million sperm per milliliter with at least 40% motility, but donor banks often want counts well above that because samples lose some viability during freezing and thawing. If your numbers don’t meet their standards, the process ends here.
Medical Screening and Background Check
If your sample passes, the next visit involves a detailed questionnaire about your family medical history, your sexual history, and your personal health. You’ll also need to clear a background check that covers criminal records, seven years of residence history, and verification of any educational credentials you’ve claimed. Sperm banks market donors partly on their profiles, so they verify what you tell them.
After that comes a full physical exam, including a genital exam and a color vision test. The real depth of the screening, though, is in the bloodwork. Federal regulations require testing for HIV (types 1 and 2), hepatitis B, hepatitis C, syphilis, chlamydia, and gonorrhea. Sperm donors specifically must also be tested for HTLV (a rare virus linked to certain cancers and neurological disease) and cytomegalovirus (CMV), a common virus that can be dangerous to developing pregnancies. Blood and urine samples cover all of these, and genetic carrier screening checks for heritable conditions like cystic fibrosis and sickle cell disease.
If any test comes back positive for a communicable disease, you’re disqualified. Even if a follow-up test is negative, the FDA does not allow a donor to be deemed eligible if they previously showed clinical evidence of a relevant communicable disease.
Psychological Evaluation
Some sperm banks include a session with a counselor as part of the screening. This serves two purposes: it confirms you’re emotionally prepared for the reality of donation, and it gives the bank confidence that you understand what you’re agreeing to. The counselor will walk you through what it means to have biological offspring you may never meet, how identity disclosure works, and what your legal relationship (or lack of one) will be to any children conceived from your samples.
What Happens on Donation Day
Once you’re approved as an active donor, you’ll schedule regular visits, typically once or twice a week. Before each donation, you’ll need to abstain from ejaculation for two to seven days. The World Health Organization recommends a minimum of two days and a maximum of seven for optimal sample quality.
At the clinic, you’ll be shown to a private room where you provide a sample through masturbation into a sterile cup. The whole visit is usually 30 minutes to an hour. Afterward, the lab evaluates the sample for quality. If it meets their standards, you get paid for that visit.
Samples are frozen through a process called cryopreservation and placed into quarantine. The quarantine period exists because some infections don’t show up on tests immediately after exposure. You’ll be retested at regular intervals, and your frozen samples are only released for use after your follow-up tests confirm you remain disease-free.
Compensation
Pay varies by bank and location. As a representative example, The Sperm Bank of California pays $200 per acceptable sample, plus bonuses. Donors who maintain a regular schedule of one to two visits per week can earn between $950 and $1,500 or more per month. Not every sample you provide will meet quality thresholds, so your actual earnings depend partly on consistency. Most banks also require a minimum commitment of six months to a year.
Legal Rights and Parental Responsibility
When you donate through a licensed sperm bank, you sign legal agreements relinquishing parental rights and responsibilities. In practice, this means you have no financial obligation to any children conceived from your samples, and no legal claim to custody or visitation.
These protections are strongest when donation goes through a medical facility. Informal arrangements carry real legal risk. In one well-known Kansas case, a man who donated sperm to a same-sex couple through a private arrangement (found via Craigslist) was ruled the legal father, despite a written agreement stating otherwise. The court’s reasoning: the insemination wasn’t performed by a physician, and the recipient wasn’t married. Even when both parties agree in writing to waive parental rights, those contracts aren’t always enforceable outside the formal sperm bank system.
Anonymity and Identity Disclosure
Whether your identity stays private depends on where you donate and what type of donor profile you choose. Many sperm banks now offer two tracks: anonymous donation, where recipients receive only a general profile, and open-identity (or “willing to be known”) donation, where donor-conceived children can request your identifying information once they turn 18.
The trend globally is moving toward disclosure. Sweden banned anonymous sperm donation in 1985. The United Kingdom maintains an open registry. Austria also favors the rights of offspring to know their genetic heritage. In the U.S. and Canada, anonymous donation is still common, but growing numbers of donor-conceived adults are pushing for change. Direct-to-consumer DNA testing has also made true anonymity increasingly difficult to guarantee regardless of what a contract says.
If you choose an open-identity program, that doesn’t mean a child will show up at your door on their 18th birthday. It means they’ll have the option to request contact through the sperm bank, and you may be asked to provide updated contact information over the years. Some donors never hear from anyone. Others are contacted by multiple offspring.
How Many Children Could Result
One thing that surprises many donors is the number of families that could potentially use their samples. A single ejaculate can be divided into multiple vials, and over months or years of regular donation, a donor can produce hundreds of vials. Sperm banks set internal limits on how many family units can use a single donor’s samples, but these limits vary. Some donors have learned through registries that they have 20, 50, or even more biological children. Understanding that possibility before you start is part of what the screening process is designed to ensure.
