Becoming a sperm donor involves an application, several weeks of medical and genetic screening, and a commitment to donate regularly for at least six months. Most sperm banks accept donors between the ages of 21 and 39, and only a small fraction of applicants are ultimately approved. Here’s what the full process looks like, from eligibility to compensation.
Basic Eligibility Requirements
Sperm banks want donors who are healthy adults, ideally 21 or older. Some banks accept applicants as young as 18, but donors under 21 typically need a psychological evaluation before they can proceed. Upper age limits vary by bank but generally cap around 39 to 40, since the risk of certain conditions in offspring (including autism) increases with paternal age.
Beyond age, you’ll need to be in good overall health with no personal or family history of serious hereditary disease. Most banks also have minimum height requirements, often around 5’7″ or 5’8″, though this varies. A history of drug use, certain chronic conditions, or high-risk sexual behavior will disqualify you. Proven fertility is preferred but not required.
The Screening Process
If your initial application is accepted, expect the screening phase to take four to six weeks. It’s thorough, covering your medical background, your family’s health history (often going back three generations), a physical exam, and extensive lab work.
The FDA requires that all sperm donors be tested for HIV-1 and HIV-2, hepatitis B, hepatitis C, syphilis, West Nile virus, HTLV (a virus that can affect white blood cells), and cytomegalovirus (CMV). Because sperm is classified as reproductive tissue, you’ll also be tested for chlamydia and gonorrhea. These aren’t one-time tests. For anonymous donors, the FDA requires a second round of testing at least six months after donation, which is why your samples are quarantined before they can be released.
Most sperm banks also run genetic screening panels even though it isn’t federally mandated. These panels check whether you carry genes for conditions like cystic fibrosis, sickle cell disease, spinal muscular atrophy, and dozens of others. The specific panel varies by bank, but the goal is to reduce the chance of pairing a carrier donor with a carrier recipient.
Semen Quality Standards
Your sperm needs to meet quality thresholds that are actually higher than what’s considered “normal” fertility. Samples are frozen and thawed before use, and not all sperm survive that process, so banks need donors who start well above average.
A standard semen analysis looks at three main factors. Sperm count should be at least 20 million total sperm per milliliter, with at least 10 million of those being motile (actively swimming). Motility itself needs to hit 50% or higher, meaning at least half the sperm in your sample are alive and moving. Progression, which measures how well sperm swim forward rather than in circles, should score a 2 or higher on a 4-point scale. Morphology (the shape of sperm cells) may also be evaluated, though some banks don’t include it in their standard analysis.
Many otherwise healthy men don’t meet these thresholds, and this is one of the biggest reasons applicants get rejected. Some banks will test two or three samples before making a final decision, since sperm quality can fluctuate.
What the Commitment Looks Like
Sperm donation isn’t a one-time event. Most banks require you to donate at least twice a week for a minimum of six months. That means living close enough to the facility to visit regularly, which is why many banks recruit near college campuses or in major metro areas.
Before each donation, you’ll need to abstain from ejaculation for two to seven days (the World Health Organization recommends this window for optimal sample quality). You’ll also be expected to maintain a healthy lifestyle during your time as a donor: limited alcohol, no recreational drugs, no new tattoos or piercings, and disclosure of any new sexual partners. Banks may do periodic retesting throughout your donor period to confirm your health status hasn’t changed.
Compensation
In the United States, sperm donors typically receive $70 to $100 per sample. If you’re donating twice a week and staying consistent, that works out to roughly $560 to $800 per month, with some donors earning over $10,000 annually. Many banks also offer bonuses for completing your full commitment period or for donors with especially high demand profiles.
Compensation varies significantly outside the U.S. In some countries, payment beyond reimbursement for expenses is prohibited entirely. In India, for context, the median compensation is about ₹800 per sample (roughly $10 USD), with annual earnings around ₹20,000 to ₹25,000.
Limits on Offspring
There’s no federal law in the U.S. capping how many children a single donor can father, but the American Society for Reproductive Medicine recommends no more than 25 families per donor in a population of 800,000. Most major sperm banks track reported births and stop distributing a donor’s samples once their internal limits are reached.
Other countries enforce stricter rules. The UK limits each donor to 10 families. The Netherlands allows 25 children per donor nationwide. Australia, New Zealand, and China cap it at 5 to 10 families per donor. If you’re donating through a U.S. bank that ships internationally, your samples could be subject to the receiving country’s limits as well.
Legal Protections and Risks
When you donate through a licensed sperm bank, you are not considered the legal parent of any resulting children. The intended parents, or the birth mother in cases of artificial insemination, hold all parental rights and responsibilities. Most states have laws explicitly protecting sperm donors from child support obligations when the donation goes through a medical professional or licensed facility.
That protection weakens considerably in informal arrangements. If you donate privately (outside of a sperm bank, without proper legal agreements), courts in some jurisdictions have ruled that the donor can be recognized as a legal parent and held liable for child support. This is especially true if conception happens through sexual intercourse rather than clinical insemination, or if the donor later takes an active role in the child’s life. If you’re considering any arrangement outside a licensed sperm bank, a reproductive law attorney is essential.
Anonymous vs. Open-Identity Donation
Most sperm banks offer two tracks. Anonymous donors have their identifying information withheld from recipients and any resulting children. Open-identity donors (sometimes called “willing to be known”) agree to allow offspring to access their identity once the child turns 18.
The trend in the industry has shifted toward open-identity donation. Several countries, including the UK, have banned anonymous donation entirely. Even in the U.S., the rise of consumer DNA testing means that true anonymity is increasingly difficult to guarantee. A donor-conceived person can submit a saliva sample to a genealogy database and potentially identify their biological father regardless of the bank’s anonymity policy. This is worth considering before you decide which track to choose, because the practical difference between the two is shrinking.
