Surrogacy Fertility Medications: What You Take and Why
Surrogacy fertility medications prep your body for embryo transfer. Here is what to expect: the meds, the timeline, and how to handle side effects.
Quick Answer
- Rocky Mountain Surrogacy coordinates all fertility medication logistics — the intended parents pay for every medication
- You take hormones to thicken your uterine lining before embryo transfer — typically estrogen and progesterone
- Side effects are mild for most surrogates: bloating, mood shifts, and soreness at injection sites
- Medication phase typically lasts 2–4 weeks before transfer, then continues 8–12 weeks after a confirmed pregnancy

Why Surrogacy Fertility Medications Matter
Surrogacy fertility medications get your body ready for an embryo. Without them, your lining may not be thick enough. The embryo needs a healthy spot to implant.
Your doctor picks the right meds for you. The plan is based on your body and your cycle. Every surrogate gets a custom protocol.
You start meds weeks before your surrogate embryo transfer. Blood tests and scans track your progress. When your lining is right, you get the green light.
The CDC Assisted Reproductive Technology page tracks IVF data across the U.S. Clinics use this data to refine med protocols. Your clinic follows the latest research.
You are never alone in this. Your agency team is there 24/7 if you have questions about your meds or your body.
Your fertility doctor creates a med plan just for you. It is based on your body, your cycle, and the best current research.
Common Surrogacy Fertility Medications You Take
Most surrogates take two types of meds, following ASRM's fertility medication guidelines. The first is estrogen. The second is progesterone. Your body makes both on its own.
Estrogen comes as patches, pills, or shots. It helps your lining grow thick. You start it weeks before transfer day.
Progesterone comes as shots or inserts. It keeps the lining stable after transfer. You take it for the first trimester.
Some plans add other items. These might be antibiotics or baby aspirin. Your doctor picks what you need.
Your surrogacy screening steps include a full check before you start meds. This makes sure your body is ready to go.
- Estrogen patches, pills, or injections to build your lining
- Progesterone injections or inserts to keep the lining stable
- Antibiotics to prevent infection before transfer
- Baby aspirin to support blood flow to the uterus
- Prenatal vitamins to support early pregnancy
