Gestational Surrogacy Timeline: Month-by-Month Guide

Phase 1: Research & Agency Selection (Months 1–2)

Before contacting any agency, spend 4–8 weeks educating yourself on the process, costs, and state laws. Consult a reproductive attorney independently — before signing with any agency — so they can review your agency agreement before you commit. Research 2–3 agencies, request itemized fee schedules in writing, and speak with past intended parents they can refer you to.

Phase 2: Matching (Months 2–6)

Once enrolled with your agency, surrogate candidates are presented based on your preferences and theirs. Review profiles, meet via video call, and confirm a match when both parties agree. Average matching time is 1–4 months, though it can be longer. Once matched, legal and medical planning typically begin in parallel.

Phase 3: Legal Contracts (Weeks 1–6 after match)

Your attorney and your surrogate's attorney negotiate and draft the Gestational Carrier Agreement. This typically takes 3–6 weeks. Some clinics may begin or coordinate certain screening steps before the final GCA, but legal clearance and a fully executed GCA are generally required before embryo transfer medication and embryo transfer. Do not rush this phase.

Phase 4: Medical Screening & Embryo Transfer

The fertility clinic schedules the surrogate's comprehensive medical evaluation: uterine assessment, bloodwork, infectious disease screening, and review of prior obstetric records. Psychological evaluation may be coordinated through the agency, clinic, or an outside professional. If she passes and legal clearance is complete, an embryo transfer protocol begins. The surrogate takes estrogen and progesterone to prepare her uterine lining. The frozen embryo transfer (FET) itself takes approximately 10 minutes. A beta-hCG blood test 10–14 days later confirms whether the transfer was successful.

Phase 5: Pregnancy (Months 1–9 after confirmed pregnancy)

After a confirmed heartbeat at 6–7 weeks, the surrogate usually graduates from the fertility clinic to her OB. Intended parents typically attend the anatomy scan at 18–20 weeks in person. Your attorney files for the pre-birth order during the second trimester when available. In the third trimester, coordinate travel logistics, hospital access, and birth preferences with your surrogate.

Phase 6: Birth & Legal Finalization

With a pre-birth order in place, you are recognized as the baby's legal parents from the moment of birth. Your names appear on the birth certificate. In states requiring post-birth proceedings, your attorney files the parentage order after birth — finalization can take several weeks or longer depending on the state and court.

Buffer Time

Build 3–6 months of buffer into your planning. Failed embryo transfers, rematching if a surrogate withdraws, or extended legal timelines can all extend the journey. Most intended parents who plan for 18 months finish within that window; those who plan for 12 often feel behind schedule when normal delays occur.
