A donor-conceived person is someone who was created using sperm, eggs, or embryos from a third party, meaning at least one of their biological parents is not the person who raises them. This applies whether the donation involved sperm, eggs, or a complete embryo. The term describes a growing population: estimates have long cited 30,000 to 60,000 sperm-donor births per year in the United States alone, and that figure doesn’t include egg or embryo donation.
How Donor Conception Works
There are three main forms of donor conception, and each one changes the genetic relationship between the child and the parents who raise them in a different way.
With sperm donation, a woman is inseminated with sperm from a man who is not her partner. The child is genetically related to the mother but not to the father figure in the household. This is the oldest and most common form of donor conception, used by heterosexual couples dealing with male infertility, single women, and same-sex female couples.
Egg donation is essentially the reverse. A donor provides eggs that are fertilized (typically with the intended father’s sperm) and transferred into the recipient mother’s uterus. The child is genetically related to the father but not to the mother who carries and delivers them. With embryo donation, neither parent shares a genetic connection with the child. A previously created embryo, often from another couple’s fertility treatment, is transferred to the recipient mother.
What Donors Are Screened For
Before someone can donate sperm, eggs, or embryos through a fertility clinic, they go through extensive medical screening. The American Society for Reproductive Medicine requires testing for syphilis, hepatitis B and C, gonorrhea, chlamydia, and HIV. Donors are also asked about risk factors like recent travel to areas with Zika virus transmission, prior organ transplants, and blood transfusions received in certain countries. Genetic evaluation is part of the process too, with donors undergoing counseling and testing to identify inherited conditions they could pass on.
These screenings protect the recipient family, but they also create an initial medical snapshot that can be valuable to the donor-conceived person later in life. One persistent challenge is that this medical history is frozen in time. A donor who develops a hereditary condition years after donating may have no mechanism to relay that information to offspring.
Legal Parentage and Donor Rights
In most U.S. states, laws remove parental rights from the donor and assign them to the intended parents. The donor has no legal claim to the child, and no legal obligation to them. However, these protections have gaps. Many state statutes only apply when the recipient is married or when a licensed physician performs the insemination. Informal arrangements, such as using a known donor without a clinic, can leave legal parentage ambiguous and potentially contested.
For the child, this legal framework means their birth certificate lists their social (non-genetic) parent as their legal parent. The donor typically has no legal relationship to the child whatsoever.
Identity and the Question of “Who Am I?”
Being donor-conceived raises questions that go beyond biology. Research on adolescent identity development shows that donor-conceived teenagers go through a process similar to adopted children: they begin making meaning out of aspects of themselves they didn’t choose. Some actively seek information about their donor and any donor siblings (half-siblings who share the same donor) out of curiosity and a desire to fill in the picture of who they are.
A study in Fertility and Sterility identified two distinct patterns in how adolescents process their donor-conceived status. Some show curiosity, characterized by openness, flexibility, and generally positive feelings about their origins. Others lean toward avoidance, marked by disengagement, anger, or anxiety about the topic. The quality of the parent-child relationship plays a significant role in which direction a young person goes. Adolescents with secure, trusting relationships with their parents were more likely to explore their donor conception openly, while those with less secure attachments tended to shut down the conversation.
When and How Children Learn the Truth
One of the biggest decisions parents face is when to tell their child. The ASRM’s ethics committee notes that many professionals and donor-conceived people themselves recommend disclosure during the preschool or early school-age years, before puberty, so the child can absorb the information gradually and feel they have “always known.” Research supports this approach: children told at a young age tend to respond with curiosity or neutrality rather than distress.
In one study of donor-conceived adolescents, about 10% said they had always known, 47% couldn’t recall a specific moment they were told, and 42% reported learning by age seven. The fact that nearly half couldn’t pinpoint when they found out suggests that early, casual disclosure tends to make the information feel like an ordinary part of a child’s story rather than a dramatic revelation.
Late discovery, on the other hand, can be destabilizing. Finding out in adulthood, sometimes through an unexpected DNA test, that a parent is not biologically related to you can shake a person’s sense of trust and identity in ways that early disclosure largely prevents.
DNA Testing Changed Everything
For decades, donor anonymity was the norm. Donors were promised their identity would never be revealed, and many recipient parents never told their children. Consumer DNA testing services like 23andMe and AncestryDNA upended that system entirely.
Among sperm donors who have been contacted by their donor-conceived offspring, nearly 80% were identified through direct-to-consumer DNA testing databases. A person simply submits a saliva sample, and the database matches them with biological relatives who have also tested. This means that even donors who were guaranteed anonymity decades ago can now be found, and donor-conceived people who were never told the truth about their origins can discover it on their own.
This shift has driven a broader legal trend. Countries including the United Kingdom and Australia have abolished donor anonymity outright, giving donor-conceived people the legal right to access identifying information about their donor once they reach adulthood. Belgium, Denmark, the Netherlands, and Portugal have moved to identity-release models as well, where donors agree at the time of donation that their identity can be shared when the child turns 18. The United States has no federal law on the matter, leaving it up to individual clinics and sperm banks to set their own policies.
Language That Donor-Conceived People Prefer
Terminology matters in this community. People born through donor conception are generally called “donor-conceived” or “donor offspring.” The adults who raise them are often referred to as “recipient parents” or “intended parents,” though everyday language like “mom” and “dad” is of course the norm within families. The term “commissioning parent” exists but is widely disliked for sounding transactional and cold.
Half-siblings who share the same donor are called “donor siblings.” You may see the word “dibling” used casually, but many donor-conceived people find it trivializing. How a family refers to the donor varies widely: some children call them “donor-dad” or “biological mother,” while others simply use “the donor.” There is no single right answer, and preferences often shift as the donor-conceived person grows up and forms their own relationship with the concept.
