In 1884, a Philadelphia physician named William Pancoast inseminated a woman with sperm from a medical student. Her husband had a low sperm count, and the doctor decided to solve the problem without telling her. The story surfaced later when a student who witnessed the procedure wrote about it. That case, which became a fixture in medical ethics literature, is the starting point for understanding the modern sperm donation process. Everything that follows today, the questionnaires, the genetic panels, the six-month quarantine, the psychological consult, exists because secrecy created problems that DNA testing later exposed.
The first 100 years of donor insemination ran on silence. From the 1940s through the 1980s, many physicians advised couples never to tell the child. Some doctors mixed donor semen with the husband's so the family could believe the child might be his. Records were often incomplete or destroyed. Donor selection could be as crude as finding a medical student who resembled the husband. A child's medical history stayed blank. Donor-conceived adults had no path to learn their genetic background or how many half-siblings existed.
That system started breaking in the 1980s and 1990s. Donor-conceived people began speaking publicly. Some countries passed laws that gave them access to donor identity. The UK ended anonymous donation in 2005, giving donor-conceived adults the right to request identifying information at 18. In the United States, no single federal law mirrors that, but the largest sperm banks now offer open-ID donors who agree to release their identity when a resulting child reaches adulthood.
Direct-to-consumer DNA testing made anonymity unenforceable. A person conceived through an anonymous donation could test with a consumer company, find third cousins, and build a family tree back to a candidate donor. That pressure did more to shift the industry than goodwill did.
What the Modern Process Screens For
The modern process has three gates: semen quality, infectious disease, and genetic risk. A psychological and legal layer wraps around all three.
First Gate: Semen That Survives Freezing
A man can have a normal semen analysis and still fail as a donor. The World Health Organization's lower reference values sit at 15 million sperm per milliliter, 39 million total per ejaculate, 4 percent normal forms, and 32 percent progressive motility. Donor programs often set the bar higher because sperm must survive freezing, storage, and thawing.
The math works like this. A fresh sample with 40 million per milliliter may drop to 12 million after thaw. A bank wants the post-thaw unit to still meet or exceed clinical thresholds, so it selects donors whose fresh parameters have enough margin. Levine and colleagues reported in Human Reproduction Update in 2023 that average sperm concentration fell from 101.2 million per milliliter to 49.0 million per milliliter between 1973 and 2018. That decline puts more men in the range where a routine fertility evaluation may be fine, but donor qualification is not. Banks also look at motility after thaw, not just count. Some samples freeze well. Others do not. The only way to know is a test freeze, which is why many programs reject applicants after the first semen analysis rather than after the full workup.
Second Gate: Infectious Disease and the Six-Month Quarantine
Under FDA regulations, donor semen is frozen and held for at least six months. The donor returns for repeat testing after that wait. The quarantine covers the window between infection and a positive test result, particularly for HIV and hepatitis B and C. Tests also include syphilis and other infections.
The semen is not released until the repeat tests come back negative. This is a hard stop. If a donor does not return for retesting, the vials remain in quarantine. The six-month wait is the reason donation is a commitment measured in months, not a single afternoon.
Third Gate: Genetic Carrier Screening
Many banks now run expanded carrier screening on donors, sometimes covering hundreds of conditions. The list often includes cystic fibrosis, spinal muscular atrophy, and sickle cell disease. The point is to avoid matching a donor and a recipient who both carry a recessive condition. If both carry the same variant, the resulting child has a 25 percent chance of inheriting the condition. Banks use the donor's panel to exclude or match against the recipient's results.
This step did not exist for most of donation history. A donor in the 1970s could carry a serious recessive condition and never know it, because the recipient was not screened either. Expanded panels are a response to that gap.
Psychological and Legal Layer
Professional guidance from the American Society for Reproductive Medicine recommends that donors receive counseling about the implications of donation, including the possibility that resulting children may contact them later. Some banks require a psychological consult. The conversation covers family disclosure, identity release, and the emotional weight of producing genetic children you may never meet or may meet at 18.
The legal agreement is separate. Contracts define whether the donor will have parental rights or obligations, how identity release works, and whether the bank or the donor controls contact. Sibling caps vary by bank and country. Some programs limit the number of families per donor to 10, others to 25 or 30. The number matters because donor-conceived people have raised concerns about large sibling pods and the difficulty of tracking medical updates across many families.
Open-ID and Directed Donation Are Different Paths
Most major US sperm banks now offer open-ID donors. Open-ID means the donor agrees to release identifying information when a resulting child turns 18, not at the time of donation. Some donors prefer anonymous programs, but consumer DNA databases have made true anonymity difficult to guarantee.
Directed donation, where a man donates to a known recipient, follows a separate process. The FDA still requires infectious disease testing and the six-month quarantine. State laws vary on parental rights and legal parentage. Some men assume a known arrangement skips the quarantine. It does not under federal rules for donated reproductive tissue.
Why Most Applicants Do Not Make It Past the First Analysis
Sperm banks reject most applicants. The first analysis eliminates men whose count, motility, or morphology does not clear the high bar. The second elimination is freeze-thaw survival. The third is a medical history or genetic screen. The fourth is failure to return for retesting.
The process is designed to reduce risk. A small number of high-quality donors can serve many families, so banks can afford to reject broadly. That is different from blood donation, which needs a large pool because a single unit has a short shelf life. Sperm can be stored for years.
What the Future Does to Anonymity
The next shift will come from whole-genome sequencing and shared DNA databases. Open-ID is already the default at many large banks. Some donor-conceived adults have used public databases to identify not just a donor but a donor's extended family. That changes the meaning of open-ID. A donor may agree to release his identity at 18, but a determined family can often trace him sooner if a relative has tested.
The process is also moving toward more detailed genetic matching. As expanded carrier panels grow, banks can match donors and recipients against dozens of recessive conditions at once. This is a targeted form of reproductive risk reduction that did not exist in the secrecy era.
The cultural shift matters too. Donation in the 1960s and 1970s was usually framed as a private favor to married couples. Today the recipient base includes single women, same-sex couples, and couples with male factor infertility. The language in screening forms and counseling has changed accordingly. The process no longer assumes a husband who wants to hide the donor's role.
If you are considering donating, ask the bank four questions before you fill out anything:
- What are the post-thaw semen thresholds?
- Which carrier conditions does the panel include?
- What is the open-ID release timeline?
- What is the sibling cap?
A program that cannot answer those four questions with specific numbers is not running a modern process.
Every questionnaire, quarantine, and consent form is a correction for the secrecy that once defined the procedure. The modern sperm donation process asks you to be traceable, healthy, genetically screened, and willing to wait.

Frequently asked questions
how long does the sperm donor quarantine last
Under FDA rules, donated sperm stays frozen for at least six months. The donor returns for repeat infectious disease testing after that window. Vials only get released once the follow-up tests come back negative. If the donor skips the retest, the samples stay in quarantine.
what sperm count do you need to be considered as a donor
The World Health Organization's lower reference sits at 15 million sperm per milliliter, but donor programs usually want more. Sperm has to survive freezing and thawing, so banks look for fresh samples with enough margin to still meet clinical thresholds after thaw. Many applicants are rejected at this first step.
can you still donate sperm anonymously
Some programs still offer anonymous donation, but true anonymity is hard to maintain. Direct-to-consumer DNA testing can connect a donor-conceived person to relatives and back to the donor. Most major US sperm banks now use open-ID donors, who agree to release their identity when a child turns 18.
what should i ask a sperm bank before applying to donate
Ask for the post-thaw semen thresholds, which carrier conditions are on the genetic panel, the open-ID release timeline, and the sibling cap. A program should be able to give you specific numbers for all four. If it can't, the donor process may not be as structured as it should be.
