What authoritative guidance actually says
The American Society for Reproductive Medicine (ASRM) recommends medical, psychosocial, infectious-disease, preconception, uterine-cavity, and legal evaluation of gestational carriers. Its 2022 committee opinion says carriers should be of legal age and preferably 21–45; ideally should have had at least one term, uncomplicated pregnancy; and ideally should not have had more than five previous deliveries or three cesarean deliveries.
Those are professional recommendations, not a universal law or a guarantee that every clinic uses identical cutoffs.

Factors that can lead to a decline, deferral, or additional review
- Pregnancy history: prior complications, preterm delivery, or other obstetric history may require closer review.
- Number of prior deliveries or C-sections: ASRM gives preferred limits, while individual clinics may use different policies.
- Current medical conditions: conditions that could increase pregnancy or treatment risk may require specialist evaluation or prevent clearance.
- Smoking, nicotine, or nonmedical drug use: programs and clinics commonly screen for substance-use risk.
- Psychosocial screening: ASRM recommends psychosocial evaluation and counseling as part of gestational-carrier screening.
- Program-specific criteria: agencies and IVF clinics may also use age, BMI, timing since the last delivery, medications, residency, or other criteria.
Does a C-section automatically disqualify you?
No universal rule says that one prior C-section automatically disqualifies a gestational carrier. ASRM's guidance says a carrier ideally should not have had more than three cesarean deliveries, but the fertility clinic still evaluates the full obstetric history and individual risk.
What about a premature birth?
A prior preterm delivery does not have one nationwide yes-or-no rule. It can trigger additional medical review because the reason, gestational age, recurrence risk, and overall pregnancy history matter. Some programs may use stricter internal criteria than others.
Can receiving public benefits disqualify you?
Receiving public benefits is not itself listed by ASRM as a medical disqualification criterion. However, a program may separately review financial stability, and compensation can have implications for benefit eligibility. Applicants should verify those issues with the program and, when relevant, a qualified benefits or tax professional.
Agency approval is not medical clearance
An agency may accept or decline an applicant under its own policies, but medical clearance is a separate decision made by the fertility clinic and treating professionals. Passing an initial intake screen does not guarantee final clearance.
