A guy who signs a sperm bank donor agreement in 2026 can expect that decision to find him again around his 60th birthday. Donor-conceived adults now take consumer DNA tests, match with distant cousins, and trace their way back to the man behind the vial number. Lifelong anonymity, the standard promise for decades, fell apart without any US federal law forcing it to. Choosing a sperm bank starts with the donor contract, not the sales brochure.
This post is for the man thinking about donation. Most coverage of sperm banks is written for recipients. I went into this research expecting the hard part to be the screening, but the contract turned out to be the part that sticks around for decades. The first pregnancies from frozen human sperm were reported in 1953 by Bunge and Sherman at the University of Iowa. Commercial cryobanks grew through the 1970s and 1980s, and anonymous donation became the default. A man could donate, get paid, and never think about it again. That version of the arrangement is gone.
What the screening actually filters for
A man who walks into a sperm bank should understand the dropout math before he spends a month in the screening funnel. The first gate is semen quality. Banks measure concentration, motility, and morphology, then freeze a sample and check how much of it survives thaw. Post-thaw motility matters more than how the sample looked fresh. The second gate is infectious disease testing for HIV, hepatitis, syphilis, and other pathogens. The third gate is genetic carrier screening for conditions such as cystic fibrosis and spinal muscular atrophy, often across panels of several hundred genes. A psychological evaluation and a three-generation family health history come next. Most applicants never finish the process. Banks rarely publish exact acceptance rates, but every stage is built to reject.
From application to first paid donation, the timeline typically runs three to six months. The schedule matters too. Many banks require two to three samples per week to stay in active status. Consecutive days lower concentration and quality, so men who can't hold that schedule wash out regardless of how good their samples are.
How anonymity collapsed in two moves
In April 2005, the United Kingdom ended donor anonymity. Under rules set by the Human Fertilisation and Embryology Authority, anyone conceived from donated sperm after that date can request identifying information about the donor at age 18. The UK acted before the DNA wave hit.
That wave started in November 2007, when 23andMe launched its direct-to-consumer genetic testing service. Over the next fifteen years, a donor-conceived person in the United States could upload a raw DNA file to GEDmatch, find a second cousin, and work backward to the donor. No US federal law required the donor to waive anonymity. Cousin matching made the promise impossible to keep. Banks adjusted by pushing open ID contracts, where the donor agrees to identifying contact at 18. The old anonymous option still appears on forms, but the fine print now bends around reality.
The four contract clauses that outlive the marketing
A sperm bank is a business. The building, the brand, the brochure photos matter less than four clauses in the donor agreement.
- Identity release. Many US banks now offer open ID donation. The donor agrees to be contactable when the child turns 18. Some banks still offer anonymous donation, but the contract should state plainly what happens if a consumer DNA test reveals the donor. If the bank refuses to discuss that scenario, pick a different bank.
- Family limit. Banks commonly cap a donor at 10 to 25 families per population area, depending on the bank. Get the number in writing for your state. A donor can end up with dozens of biological children across a region. The cap is a promise, not a law.
- Compensation and exclusivity. Donors at major US banks typically earn a few hundred dollars per month, paid per accepted sample. Exclusivity clauses can prevent you from donating elsewhere. Read them. If a clause follows you to another state or country, you want to know before signing.
- Genetic carrier screening. The bank should screen for a defined list of autosomal recessive conditions. Ask for the panel size and whether it includes conditions common in your ancestry. Running your own expanded carrier screen before you apply gives you a baseline to compare against the bank's numbers.
The donor shortage is a men's health story
Sperm banks run a business on a shrinking resource. Meta-analysis data from Levine and colleagues, published in Human Reproduction Update in 2023, documents a roughly 50 percent decline in sperm concentration globally over the past several decades. Researchers debate the causes. The practical effect on sperm banks is fewer men passing the first screening gate.
Heat exposure adds another wrinkle. Sauna-level heat temporarily lowers sperm count and can worsen morphology (Garolla et al., Human Reproduction, 2013). The effect reverses once the heat stops. A man who spent the week before screening in a sauna may be evaluated at his worst, not his baseline. Understanding what the screening measures matters for that reason. For some men, the screening process is the first look at their own fertility. The bank is not a clinic, and the results are not a diagnosis. The data is still real. If your numbers come back below the bank's thresholds, that information is worth taking to a doctor who can interpret it.
What ten more years could do to your signature
A man donating today commits to a relationship that runs decades. The child born from his sample turns 18 in 2044. The legal and genetic landscape will not stand still for 18 years. Several US states have introduced or passed bills governing donor conception records. Direct-to-consumer genetic testing keeps getting cheaper. Whole-genome sequencing has fallen from roughly $100 million for an individual genome twenty-five years ago to under $1,000 today, according to National Human Genome Research Institute data. Within a decade, an adult searching for a donor may run a full genome and match a donor's third cousin without ever touching a commercial genealogy database.
In vitro gametogenesis, the process of creating sperm or eggs from stem cells, has been demonstrated in mice and is under active research in humans. If it becomes clinically available within a donor's horizon, the sperm bank model itself changes. This is emerging research. It is not a settled outcome. The only reasonable assumption is that the rules will not stay the same.
A short checklist before you apply
If you are considering donation, do four things before you choose a bank.
- Request the donor agreement from at least two banks and read the identity release language line by line.
- Run an expanded genetic carrier screening with a lab that reports panel size and variant coverage.
- Talk to a donor-conceived adult. Ask what they wish donors had known when they signed.
- Look up your state's laws on donor records. A few states have moved faster than others on identity release, and the bank may not volunteer that difference.
Donation was once a transaction with an expiration date. It no longer is. The brochures still describe the old arrangement. The contract describes the new one. Read the contract. The terms you sign now cover a relationship that may outlive the bank itself.

Frequently asked questions
how anonymous is sperm donation now
True anonymity is effectively gone. A donor-conceived person can use a consumer DNA test, upload the raw data to a database like GEDmatch, and work backward from a distant cousin. Many US banks now offer open ID contracts, where the donor agrees to identifying contact at age 18.
what do sperm banks test for
Sperm banks screen semen quality first, including concentration, motility, and how much survives freezing and thaw. They also test for infectious diseases such as HIV and hepatitis, run genetic carrier panels for hundreds of conditions, and require a family health history and psychological evaluation. Most applicants never make it through the full process.
can sauna use affect sperm bank screening
Sauna-level heat can temporarily lower sperm count and worsen morphology, an effect that reverses after heat exposure stops. If you sauna heavily the week before screening, you may be evaluated at a temporary low rather than your baseline. The bank is not a clinic, so any low result is worth taking to a doctor.
what should I look for in a donor agreement
Read the identity release clause first, then the family limit, compensation and exclusivity terms, and the genetic carrier screening details. Ask the bank what happens if a consumer DNA test reveals your identity, and get the family limit in writing for your state. If the bank won't discuss those points, choose a different bank.
