Core requirements
Age 21–40
Some clinics extend to 45 depending on health history; 21–38 is the most common sweet spot.
At least one prior pregnancy
You'll need to have given birth before, with no major complications during pregnancy or delivery.
Currently raising at least one child
Most programs require you to be actively parenting at least one child of your own.
Healthy BMI
Generally between 18 and 32, though this varies slightly by clinic.
U.S. citizen or legal resident
Required for legal and insurance purposes in most U.S.-based programs.
Non-smoker, drug-free
No nicotine, recreational drugs, or excessive alcohol use — verified through screening.
Lifestyle & stability requirements
Beyond the medical basics, programs look for stability — a safe, supportive home environment, financial independence (not currently receiving certain forms of government assistance), and the ability to attend medical appointments and travel if needed for the pregnancy.
What disqualifies someone — and what doesn't
Things that typically don't disqualify you
- A prior C-section, in most cases
- Being single (no spouse or partner required)
- Having a tubal ligation
- Renting rather than owning your home
- A past, fully resolved mental health diagnosis
Things that typically do disqualify you
- Current high-risk pregnancy complications (severe preeclampsia history, uterine abnormalities)
- Active substance use
- BMI significantly outside the healthy range
- Unstable housing or significant unaddressed mental health concerns
"Requirements exist to protect you and the baby — not to gatekeep for the sake of it. If you're unsure whether you qualify, the only way to know for sure is to ask."
How qualification is actually determined
You'll start with a simple application covering the basics above. If that looks like a good fit, the next step is a deeper medical and psychological screening with a fertility clinic — that's where the real, individualized answer comes from, not a checklist alone.
