Using Donor Sperm: Fertility Options, Process, and What to Expect
Who uses donor sperm, how to choose a donor, and what the clinical and legal path looks like. For anyone building a family through donor conception.
Donor sperm is one of the more quietly common paths in fertility medicine — used by single parents by choice, same-sex couples, and people navigating severe male-factor infertility. The clinical process is more straightforward than many people expect; the decisions around donor choice, disclosure, and legal setup take considerably more thought. This page covers the full path from who uses donor sperm to what you'll want to think through before telling your child.
What is donor sperm and who uses it?
There are three main paths that bring people to donor sperm: male-factor infertility (including severe oligospermia, azoospermia, and cases where surgical sperm retrieval has not been successful), single parents by choice, and LGBTQ+ family building — most commonly same-sex female couples and single mothers by choice. There is no primary or more legitimate reason to use donor sperm. The clinical process is the same across all three paths. The emotional landscape, family conversations, and legal considerations do differ meaningfully depending on circumstances, but no one path is more valid than another.
How do you choose a sperm donor?
The first decision is whether to use a known donor — a friend, acquaintance, or rarely a family member — or an anonymous or ID-release donor through a sperm bank. Known donors offer a pre-existing relationship and often more direct health history, but legal agreements are essential even when everyone is aligned and intentions are clear; the absence of formal paperwork creates real risk later. For donors through a sperm bank, the depth of genetic screening varies significantly between banks. It is worth examining which genetic conditions are included in the carrier screening panel, what open-ID options exist, and how many families per donor the bank limits — that family cap affects how many donor-conceived siblings your child may eventually have.
What is the difference between open-ID and anonymous donors?
Open-ID donors agree to allow donor-conceived people to access identifying information once they reach adulthood, typically at age 18. Anonymous donors have traditionally not agreed to this. However, the distinction between "open-ID" and "anonymous" has become significantly less meaningful in practice: commercial DNA databases now allow most donor-conceived people to identify their biological donor regardless of the original agreement, whether that agreement was made last year or two decades ago. Planning family conversations and disclosure with that reality in mind — rather than the privacy assumptions of an earlier era — is the more realistic and honest approach for families forming now.
How does IUI with donor sperm work?
IUI (intrauterine insemination) with donor sperm is the starting point for most people using donor sperm in the absence of female-factor infertility. Washed donor sperm is placed directly into the uterus around the time of ovulation, timed to the natural cycle or with mild ovarian stimulation. IVF with donor sperm is the path when there is a co-existing female-factor issue — such as a tubal problem, poor ovarian response, or prior failed IUI cycles. Donor sperm vials typically run $600–$1,200 each, with IUI-ready washed vials at the higher end of that range; IUI cycle costs are billed separately. Multiple vials may be needed across cycles, and sperm banks generally ship directly to a clinic — home insemination without a provider carries both legal and clinical risk that is worth understanding before proceeding.
What are the success rates of IUI with donor sperm?
Success rates for IUI with donor sperm mirror the general IUI success rates for the receiving partner's age and clinical picture. The sperm source — donor versus partner — does not add a success-rate advantage in the absence of male-factor infertility on the receiving side; what drives the outcome is the age and fertility status of the person carrying the pregnancy, along with any co-existing conditions. If there are co-existing female-factor issues, those need to be evaluated and factored into the prognosis independently before deciding between IUI and IVF.
What does a sperm bank test for before releasing a donor sample?
Sperm banks screen donors for infectious diseases, genetic conditions, and general health history before making samples available to recipients. The depth of that screening varies by bank: some run comprehensive multigene carrier panels while others use more limited testing. When evaluating a sperm bank, it is worth asking specifically which genetic conditions are covered in their carrier screening panel, how the bank handles positive screening results, what open-ID options are available to donor-conceived people, and what the per-donor family limit is. These are reasonable questions that reputable banks expect to answer.
What are the legal rights and limitations of sperm donors?
The legal landscape for donor sperm depends on state law and on the specific family structure. For opposite-sex married couples, the legal path is typically straightforward: the donor holds no parental rights, and the spouse is presumed to be a legal parent. For single parents and same-sex couples — including those who are married — additional legal steps are often required, including second-parent adoption or a pre-birth order, to establish full legal parentage for a non-gestational or non-biological parent. These requirements vary significantly by state and can change. A family-law attorney is not optional for any family structure where parentage is not automatically established by marriage under applicable state law.
