Single mother by choice, often shortened to SMC, describes women who decide to have a child on their own, without waiting for a partner. It’s one of the fastest-growing paths into SCRC’s practice, and the women who choose it arrive with a very consistent set of questions: what medical options exist, how donor sperm actually works, whether the law protects their parental rights, and whether insurance will help pay for any of it.
The honest answer is that single motherhood by choice is more medically straightforward and more legally protected in California than most people expect. The bigger decisions are usually about timing and sequencing, not whether it’s possible. Here’s how the path typically breaks down, from your first fertility test through establishing legal parentage.
THE SHORT ANSWER
Most single women pursuing parenthood start with a fertility assessment (AMH, antral follicle count, and a uterine evaluation), then choose donor sperm from a licensed sperm bank or a known donor. If your testing is normal and you’re under about 35, IUI with donor sperm is often the first step; IVF becomes the better starting point with age, diminished ovarian reserve, or after a few unsuccessful IUI cycles. Under California Family Code Section 7613, using a licensed physician or sperm bank automatically makes you the sole legal parent, with no additional court action required. Insurance coverage for the fertility treatment itself may apply under SB 729 regardless of relationship status, though donor sperm and shipping costs are typically billed separately and are rarely covered.
WHY IT MATTERS
Why more women are choosing motherhood without a partner
The median age at first marriage in the U.S. has climbed for decades, but the biological window for pregnancy hasn’t moved with it. Many women who assumed they’d have a partner by their mid-30s find themselves single with age becoming a bigger factor in their fertility than they’d planned for, and increasingly, they choose to stop waiting.
California has made that choice easier than it used to be, in two specific ways. First, the state’s parentage law was written with donor conception in mind: it protects a woman’s sole legal parentage without requiring a partner, a marriage, or even a court proceeding, as long as conception happens through a licensed physician or sperm bank. Second, older insurance definitions of “infertility” typically required a documented period of heterosexual intercourse, which effectively excluded single women from qualifying no matter their actual fertility. SB 729, which took effect in 2026, replaced that definition with one based on medical need, opening insurance-covered treatment to single patients on the same basis as anyone else.
None of that removes biology. Egg quality and quantity still decline with age regardless of relationship status, which is why the first real decision for most single women isn’t which method to use, but how soon to get tested.
PLAN YOUR PATH
Six steps to plan your path to single motherhood
Work through these roughly in order. The first two determine your medical starting point; the rest are the logistics that are easy to overlook until they cause a delay.
1
Start with a fertility assessment, not a decision
Before choosing between IUI and IVF, get an AMH level, antral follicle count, and a basic uterine evaluation (typically a saline sonogram or HSG). These tell you your current egg supply and rule out anatomical issues that would change your plan. Doing this first, rather than starting with insemination and adjusting later, is the single biggest factor in avoiding wasted cycles.
Ask: “Based on my AMH and antral follicle count, does my testing support starting with IUI, or would you recommend moving straight to IVF?”
2
Choose your sperm source: bank donor or known donor
Most patients use a licensed sperm bank, which screens donors for infectious disease under FDA regulation and provides detailed donor profiles, some with childhood photos, voice recordings, or staff interview notes. A known donor, such as a friend, gives you more information about the person but requires a separate legal agreement and additional screening that a bank handles automatically.
Ask: “If I use a known donor instead of a bank, what additional screening and legal steps would your clinic require before treatment?”
3
Understand California’s parentage protections
Under Family Code Section 7613, a sperm donor who provides semen to a licensed physician or licensed sperm bank is not treated as the child’s legal parent, and you’re established as the sole legal parent automatically, without a court order. That protection changes if insemination happens outside a medical setting: a known donor arrangement done at home needs a signed agreement before conception, or the donor can later be found to have parental rights and obligations.
Ask: “If I conceive using a bank donor through your clinic, do I need to take any additional legal steps to be recognized as the sole parent?”
4
Decide how many donor sperm vials to secure
Popular donors sell out, sometimes permanently, and most banks won’t guarantee a donor will still be available if you want a second child from the same donor later. Many single patients purchase several vials from one donor upfront, both to cover a few treatment cycles and to preserve the option of a full biological sibling down the road.
Ask the bank: “How many vials are currently in stock from this donor, and what’s your policy if I want more from the same donor in a few years?”
5
Confirm your insurance and cost plan
SB 729 requires many large-group fully insured California plans to cover infertility diagnosis and treatment, including IUI and IVF, regardless of relationship status. That coverage applies to the medical procedure. Donor sperm itself, cryostorage, and shipping fees are billed by the sperm bank separately from your clinic and are rarely covered by insurance, so plan for those as an out-of-pocket cost even if your treatment is covered.
Ask your insurer: “Does my plan’s infertility benefit apply to treatment for a single patient, and does it cover IUI and IVF regardless of the reason for donor conception?”
6
If you’re not ready yet, consider egg freezing now
If you know you want to be a parent but aren’t ready to start, freezing your eggs preserves more options than waiting does. Egg quality is tied to age at the time of freezing, not the age you eventually use them, so eggs frozen at 32 generally give you better odds later than eggs frozen at 38, even if you don’t use them for years.
CHOOSING YOUR METHOD
Matching your testing to a starting method
This is a general starting guide. Your reproductive endocrinologist will tailor a recommendation to your specific results.
| Your profile | Where most patients start | Why |
|---|---|---|
| Under 35, normal ovarian reserve, open fallopian tubes | IUI with donor sperm | Lower cost and less invasive, with reasonable per-cycle odds when reserve and anatomy are normal |
| 35–37, normal reserve, no other findings | IUI or IVF, depending on other testing | Age begins to reduce IUI’s per-cycle efficiency, so many patients move to IVF sooner |
| 38+, or diminished ovarian reserve at any age | IVF with donor sperm, often with PGT-A | IVF allows embryo selection and higher per-transfer odds even as egg yield declines |
| Very low reserve, advanced maternal age, or prior failed IVF | IVF with donor sperm and donor eggs | Donor eggs remove the age-related egg-quality factor, which raises success rates significantly |
WHAT EVERY PATH INVOLVES
What every path has in common
Regardless of which method you start with, a few logistics apply across the board.
- Sperm bank screening: FDA regulation requires infectious disease testing. While not required, genetic carrier screening is highly recommended before a bank can release donor sperm for use.
- Donor sibling connections: Many banks offer a sibling registry that lets your child later connect with donor siblings, if you choose to participate.
- Legal parentage through a licensed provider: Conceiving through a licensed physician or sperm bank establishes your sole legal parentage automatically under California law, no court order needed.
- Known donor agreements: If you choose a known donor, a signed legal agreement before conception is essential, regardless of whether insemination happens at a clinic or at home.
- Insurance verification: SB 729 coverage for the treatment itself may apply regardless of relationship status, but confirm your specific plan before you start.
QUESTIONS TO BRING TO YOUR CONSULTATION
Questions to bring to your first fertility consultation
Bring this list to your first appointment. A clinic that’s done this before will have specific, direct answers to all of it.
- What do my AMH and antral follicle count suggest about my egg supply and timeline?
- Based on my testing, would you recommend starting with IUI or moving straight to IVF?
- How many vials of donor sperm should I plan to secure, and does the bank offer any guarantee?
- What’s the legal difference between an anonymous, open-ID, and known donor in California?
- Do I need a lawyer, or does treatment through your clinic establish my parentage automatically?
- Does my insurance plan cover IUI or IVF under SB 729, and what does it exclude?
- If I’m not ready to conceive now, would freezing my eggs meaningfully help later?
- Realistically, how many cycles should I budget for before we’d reconsider the approach?
PLAN AHEAD FOR THESE
Situations that call for extra planning
None of these are reasons to stop. They’re the things that cause delays when they’re discovered too late.
- Choosing a known donor without a signed legal parentage agreement before conception
- Inseminating with a known donor’s sperm at home, outside a licensed physician’s care
- Assuming every sperm bank screens donors to the same standard — screening practices vary
- Not confirming your insurance plan’s stance on IUI or IVF before your first cycle
- Waiting to test ovarian reserve until after several unsuccessful IUI attempts
- Buying a single vial of donor sperm without checking the bank’s remaining supply
- Not planning ahead if you might want a full biological sibling from the same donor later
COMMON QUESTIONS
Frequently asked questions
No partner is required. If you conceive using an anonymous or open-ID donor through a licensed physician or sperm bank, California Family Code Section 7613 makes you the sole legal parent automatically, with no court order needed. If you use a known donor, you should still have a signed legal agreement in place before conception, since that protection depends on the arrangement being documented, not on your relationship status.
An anonymous donor’s identity is not shared with you or your child. An open-ID donor agrees to be contacted once the child turns 18, typically through the sperm bank. A known donor is someone you already know, such as a friend, and requires the most legal planning since the relationship exists outside the bank’s standard screening and consent process.
IVF has a meaningfully higher success rate per attempt than IUI, especially past the mid-30s, and it allows genetic testing of embryos before transfer. IUI is less invasive and less expensive, and remains a reasonable first step for younger patients with normal ovarian reserve and open fallopian tubes. Your fertility testing, not your relationship status, is what should drive this decision.
SB 729 requires many large-group, fully insured California health plans to cover infertility diagnosis and treatment, including IUI and IVF, using a definition based on medical need rather than relationship status. Confirm your specific plan, since self-funded employer plans, small groups that didn’t elect the benefit, and some other plan types fall outside the mandate.
There’s no universal number, but many single patients purchase enough vials upfront to cover several treatment cycles and to preserve the option of a full biological sibling later, since popular donors can sell out permanently. Ask the bank directly about current inventory for the donor you’re considering.
Yes. Low ovarian reserve reduces the odds of success using your own eggs, but it doesn’t rule out pregnancy. Depending on your specific results, your options may include IVF with your own eggs at a lower expected success rate, or IVF using donor eggs, which removes the age-related egg-quality factor and substantially raises the odds of success.
