If you are researching IVF in Philadelphia, success rate data is probably one of the first things you have looked for. Philadelphia is home to some of the country’s most established fertility programs, and every one of them is required by federal law to report annual cycle outcomes to SART (Society for Assisted Reproductive Technology) and the CDC.
The challenge is knowing what those numbers actually mean and what questions to ask before choosing a clinic. This guide breaks down SART-reported Philadelphia IVF success rates, explains what drives the results you see, and identifies the factors that shape your individual probability of success.
Philadelphia IVF Success Rates by Age Group
The table below compares RMA Philadelphia’s SART final report against the SART national average. All figures represent live births per intended egg retrieval, counting all embryo transfers (fresh and frozen) that follow a single retrieval cycle. This is the most comprehensive IVF success metric available, and the one most relevant to patients planning treatment.
As SART cautions on every clinic report:“A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches, and entry criteria for ART may vary from clinic to clinic.” Use this data as a directional reference and a starting point for your research. To look up published outcomes for any other Philadelphia-area clinic, use the free SART clinic search tool or the CDC ART Success Rates application.
| Age Group | National Avg. Live Birth Rate | RMA Philadelphia Live Birth Rate | Difference vs. National |
|---|---|---|---|
| Under 35 | 53.2% | 58.8% | +5.6 pts |
| Ages 35–37 | 39.9% | 57.4% | +17.5 pts |
| Ages 38–40 | 26.2% | 34.3% | +8.1 pts |
| Ages 41–42 | 13.2% | 12.0% | –1.2 pts |
| Over 42 | 4.1% | 9.1% | +5.0 pts |
RMA Philadelphia tracks above the national average in four of five age groups, with the most striking gap in the 35–37 bracket. That result highlights the impact of comprehensive PGT-A (Preimplantation Genetic Testing for Aneuploidy, a type of preimplantation genetic testing), which allows specialists to select healthy embryos for implantation.
The 41–42 age group shows RMA Philadelphia 1.2 points below the national average. That happens because RMA Philadelphia transfers only one embryo at a time, even in lower-probability age groups. Some clinics may transfer two or more embryos, which can increase the chances of success but also raises the risk of twins, which may not always be a patient’s desired outcome.
Why Philadelphia Patients Often Have Access to Stronger Fertility Care
Philadelphia has one of the densest concentrations of academic medical centers in the country. Penn Medicine, Jefferson Health, Temple University Health System, and Drexel University College of Medicine all operate within the city. That creates a competitive ecosystem for reproductive medicine and gives fertility clinics direct access to subspecialty consultants, such as reproductive immunologists, hematologists, maternal-fetal medicine physicians, and oncofertility specialists.
Embryology is a precision skill that improves with practice. Programs that perform a high number of cycles per year maintain more experienced embryology teams, tighter quality control, and more refined stimulation protocols. RMA Philadelphia performed 2,467 IVF cycles in 12 months across four clinical locations, all served by a single dedicated IVF laboratory that centralizes technical expertise. In 2026, Newsweek and Statista recognized RMA Philadelphia among America’s Best Fertility Clinics, based on ART outcome metrics, a survey of more than 4,000 medical professionals, accreditation data, and patient reviews.
Beyond Age: What Affects Your Personal Odds
Age is the strongest predictor of IVF success with your own eggs, but several other variables shape individual outcomes significantly.
Your diagnosis
The reason you need IVF affects your probability of success. For example, patients with blocked fallopian tubes often respond well once embryo transfer bypasses the obstruction. However, patients with diminished ovarian reserve may produce fewer eggs per retrieval regardless of age, which reduces the number of embryos available for genetic testing and transfer. The CDC’s national ART summary shows that diminished ovarian reserve was a reported factor in 26.2% of ART cycles nationally.
Embryo quality and genetic testing
A retrieved egg is not the same as a viable embryo. Fertilization rates, early development, and chromosomal normality all filter the field between retrieval and transfer. PGT-A confirms chromosomal normality before transfer, which significantly improves per-transfer success rates for patients 35 and older. The SART national data shows that 85.9% of embryo transfers nationally are now single-embryo transfers, reflecting how broadly this quality-first approach has been adopted.
Transfer protocol
Most high-volume programs now default to frozen embryo transfer rather than fresh transfer immediately after retrieval. Freezing allows the body to recover from ovarian stimulation, enables better endometrial preparation, and makes genetic testing possible before any transfer takes place.
Uterine factors
Fibroids, polyps, adenomyosis, or a uterine septum can impair implantation independent of embryo quality. These are typically identified through hysteroscopy or saline sonogram before a cycle begins and corrected before any transfer is attempted.
Questions to Ask Philadelphia IVF Clinics About Success Rates
Published SART data gives you a starting point, but a consultation is where you gather the information that actually applies to your situation. These are the questions we recommend asking when it comes to Philadelphia IVF success rates:
- Which metric are you quoting when you cite a success rate? Ask for the live birth rate, not the pregnancy rate. Ask whether it is per transfer or per intended retrieval, and request data specific to your age group.
- How many cycles did you perform in my age group last year? Success rate percentages based on small sample sizes may be less reliable. The more cycles, the more you can trust the data.
- Is your IVF laboratory in-house and dedicated exclusively to reproductive medicine? Shared or outsourced lab arrangements introduce variability and reduce the team’s specialization. A dedicated, high-volume in-house lab means your embryos are handled by staff whose entire focus is reproductive medicine.
- What does your process look like after a failed cycle? A strong program will describe how it analyzes what happened and adjusts protocol before the next attempt. Their experts should review embryo development data, reassess stimulation response, and evaluate implantation factors.
