Southern California's fertility care market is vast, but patients searching for a practice with genuine institutional depth, a large physician group, and a track record measured in decades have relatively few options. Reproductive Partners Medical Group (RPMG) is one of them. Founded more than 35 years ago and now operating four locations, RPMG serves patients throughout Long Beach, the South Bay, Beverly Hills, and — via its Orange County footprint — communities from Seal Beach and Huntington Beach to Newport Beach. The practice joined the Ivy Fertility network in 2021, connecting its physicians to outcomes data and peer collaboration across 27 offices in nine states. With a 4.7-star patient rating and more than 10,000 healthy births attributed to the practice, RPMG holds a prominent position among fertility clinics in California.
Physicians and Clinical Team
RPMG's physician roster reflects a consistent training pedigree: nearly every reproductive endocrinologist on staff completed fellowship at UCLA, UCSF, USC, or Yale — institutions that anchor academic reproductive medicine on both coasts.
Dr. Marli Amin, MD serves the Long Beach location as one of its two attending reproductive endocrinologists. She holds dual board certifications in Reproductive Endocrinology & Infertility and Obstetrics & Gynecology, completed her OB/GYN residency at UC Irvine, and earned her REI fellowship at UCLA. Her clinical focus spans IVF, IUI, egg freezing, and comprehensive fertility evaluation.
Dr. Eric Han, MD joined the Long Beach team after completing his residency and fellowship at Yale School of Medicine — a rarity in a market dominated by University of California training. Dr. Han earned his medical degree from the University of Connecticut School of Medicine in 2016 and finished his REI fellowship in 2023. His subspecialty interests include fertility preservation and advanced hysteroscopic surgery.
The broader RPMG group brings additional depth. Dr. Gayane Ambartsumyan, MD, PhD — the group's medical director per SART records — earned her PhD in stem cell biology and completed residency and REI fellowship at UCLA. Dr. Wendy Chang, MD trained at Harvard affiliates (Brigham and Women's, MGH, Children's Hospital Boston) before fellowship at UCLA. Dr. Jackie Ho, MD, MS holds an MS in Clinical Research from UCSF, a Top Doctor designation from Los Angeles Magazine, and published research on oncofertility and oocyte outcomes. Dr. Andy Huang, MD, MBA, Dr. Carrie Wambach, MD, and Dr. Meredith Brower, MD complete the roster — all board-certified in Reproductive Endocrinology and Infertility. Several physicians hold clinical faculty appointments at UCLA, UCSD, and UC Irvine, and the group is represented on the editorial boards of Fertility and Sterility and the Journal of Assisted Reproductive Genetics.
Services and Treatments
Long Beach patients have access to a full menu of reproductive medicine services at the Worsham Avenue clinic: IVF (conventional stimulation and freeze-all protocols), IUI, egg freezing and fertility preservation, preimplantation genetic testing (PGT-A, PGT-M, and PGT-SR), donor egg and sperm cycles, gestational surrogacy coordination, male infertility evaluation, recurrent pregnancy loss workup, and LGBTQ+ family-building including reciprocal IVF. The clinic's weekend hours — 7:30 AM to noon on Saturdays and Sundays — make early-morning monitoring appointments accessible for working patients, a practical detail that is easy to overlook when comparing practices in this market.
Laboratory and Success Rates
RPMG's laboratory holds accreditation from the College of American Pathologists (CAP) — the gold standard in laboratory quality — and has maintained that accreditation for more than 30 years. The lab's lineage traces to founding directors Dr. David Meldrum and Dr. Bill Yee, who contributed to the first successful frozen embryo transfer in the United States and helped establish the protocols that underpin modern IVF embryology.
SART outcome data for the 2023 cycle year (the most recent final report) provides a meaningful benchmark. Across all patient age groups, RPMG's live birth rate per egg retrieval — counting all cumulative embryo transfers — ranged from 43.6% for patients under 35 (out of 259 cycle starts) to 38.3% for ages 35–37, 33.1% for 38–40, and 14.8% for ages 41–42. For a single embryo transfer, live birth rates were 33.2%, 29.7%, 25.5%, and 12.6% respectively. The practice documented 3,302 total cycles in the reporting period, a volume that places it among the higher-throughput programs in Southern California. Singleton birth rates exceeded 96% for patients under 35, reflecting the group's single-embryo transfer emphasis. For patients considering the full picture of what IVF cycles can realistically achieve, reviewing the SART data alongside these statistics provides important context.
The complete outcomes report is publicly accessible through the SART Clinic Summary Report for Reproductive Partners.
Patient Experience
Across 89 Yelp reviews and broader online feedback, RPMG patients consistently highlight clinical competence and physician accessibility. Patients working with Dr. Brower describe her as "informative, communicative, empathic, and encouraging" — qualities that carry real weight in a specialty where anxiety runs high. Long Beach patients of Dr. Han and Dr. Amin note rigorous protocols paired with genuine responsiveness on results.
Some reviews reflect the reality of a multi-physician group practice: the care model emphasizes standardized protocols and team-based coordination rather than single-physician continuity at every visit. For patients who prioritize consistent high-quality standards over always seeing the same doctor, this works well; for those who want one physician at every appointment, it is worth clarifying scheduling expectations upfront.
The Long Beach office at 3833 Worsham Ave, Suite 300 sits near the I-405, accessible from across the South Bay and northern Orange County, and operates Monday through Friday 7:30 AM–4:00 PM and weekends 7:30 AM–noon.
Considering At-Home Insemination?
Not every fertility journey begins in a clinic. At-home intracervical insemination (ICI) is a lower-cost, private option that suits patients with no known fertility diagnosis — including single parents by choice, same-sex couples, and people who want to try a few cycles before committing to clinical treatment.
At-home insemination kits like those from MakeAMom come with step-by-step instructions designed for donor or partner sperm. Kits are a one-time purchase that can be reused until conception succeeds, require no clinic visit, and arrive in plain, discreet packaging. Many patients use them as a first step while working toward a fertility consultation — or alongside ovulation tracking while they wait for an appointment slot.
If you have a known fertility diagnosis, have been trying for 12 months without success (six months if you're over 35), or your physician has already recommended IUI or IVF, a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
California's fertility insurance environment changed materially on January 1, 2026, when Senate Bill 729 took effect. The law requires large-group commercial health plans — those covering 100 or more employees — to include coverage for fertility treatments, including IVF. This is a substantial expansion from prior mandates, which limited most required coverage to infertility diagnosis rather than treatment.
Patients with qualifying employer plans should verify the specific terms of their coverage: cycle limits, lifetime dollar maximums, cost-sharing requirements, and network status for RPMG. RPMG participates in numerous insurance plans and its billing team can assist with benefits verification and prior authorization. For services that fall outside plan coverage — elective fertility preservation, PGT add-ons, or donor cycles in some cases — the practice offers financing options; contact the Long Beach office at (714) 702-3000 for current program details.
Frequently Asked Questions
Who are the physicians at the Long Beach RPMG location? The Long Beach clinic at 3833 Worsham Ave is staffed by Dr. Marli Amin, MD (dual board-certified, UCLA fellowship) and Dr. Eric Han, MD (Yale-trained, fellowship completed 2023). Other RPMG physicians at Beverly Hills and South Bay locations are available for consultation, and the group's protocols are shared across all sites.
Does RPMG have its own embryology laboratory? Yes. RPMG operates a CAP-accredited embryology laboratory that has held accreditation for more than 30 years. The lab was co-founded by fertility pioneers Dr. Bill Yee and Dr. David Meldrum, and the medical director per SART records is Dr. Gayane Ambartsumyan, MD, PhD.
Does RPMG treat LGBTQ+ patients? Yes. RPMG offers reciprocal IVF, donor sperm cycles, donor egg services, and gestational surrogacy coordination for same-sex couples and single parents by choice. Patients consistently describe the practice as welcoming regardless of family-building path.
How does California SB 729 affect fertility treatment coverage? If your employer plan covers 100 or more employees, SB 729 (effective January 1, 2026) requires your insurer to include IVF coverage. Coverage terms — including cycle caps, cost-sharing, and network designations — vary by plan. RPMG's billing staff can help confirm whether the practice is in-network and what prior authorization is required before treatment begins.
