Gayane Ambartsumyan, MD, PhD

About

Her name is the one attached to the numbers on this site. The SART clinic report for Reproductive Partners Medical Group — 3,302 treatment cycles in the 2023 final reporting year, filed under clinic ID 2254 — lists Dr. Gayane Ambartsumyan as the practice’s medical director. She works out of the South Bay campus in Torrance, the office whose address is the one registered with SART, and she holds the seat where laboratory standards, reporting and cycle protocol get settled.

The credentials behind that seat are unusually scientific for a private fertility practice. She trained entirely at UCLA — biochemistry undergraduate degree, MD from the David Geffen School of Medicine, obstetrics and gynecology residency completed in 2012, and a three-year Reproductive Endocrinology and Infertility fellowship finished in 2015 — and she also holds a UCLA doctorate in molecular biology with a stem cell focus. She is board-certified in both obstetrics and gynecology and in reproductive endocrinology and infertility. That combination shows up in where she speaks: the American Society for Reproductive Medicine and the International Society for Stem Cell Research, with a list of journal articles and book chapters behind her. For a patient reading a PGT report, the practical version is that the medical director can explain what the embryology and the genetics assay actually say.

She is also trilingual, which is why Armenian and Spanish appear in this practice’s published language list: she consults in English, Armenian and Spanish, and serves a South Los Angeles and Torrance patient population where that matters. She has described working through infertility herself, and says it shapes how she handles the parts of a cycle that are not medical — the waiting, the second opinion, the cycle that came back negative. Her stated aim is patients who feel informed rather than reassured.

Clinical Expertise

• Cycle oversight as medical director: responsibility of record for the SART-reported outcomes of a three-campus program, which includes laboratory practice and reporting accuracy
• IVF with ICSI: full-cycle management for male factor, prior fertilization failure and complex cases
• PGT-A decision-making: trophectoderm biopsy at blastocyst stage with the sample run at an outside genetics laboratory, and an honest read of what a “mosaic” or aneuploid result means
• Donor egg and third-party reproduction: cycles using banked or directed donor eggs, including gestational carrier paths for male couples and single parents
• Diminished ovarian reserve and advanced maternal age: protocols for patients whose response curve is the problem rather than the tubes or the sperm
• Stem cell and reproductive biology research: presenting at ASRM and ISSCR, and translating that literature into counseling about embryo potential

Why Choose Dr. Gayane Ambartsumyan

She signs the outcome report. Choosing a clinic usually means trusting a marketing page. The medical director named on the SART filing for 3,302 cycles is the physician whose accountability is documented, not advertised.

A doctorate in molecular biology on a private-practice roster. The stem cell background is directly relevant to embryo culture, cryopreservation and PGT interpretation — the three lab variables that decide whether a cycle produces a transferable embryo.

Care in your own language. English, Armenian and Spanish consultations, in a practice that also accepts international patients from six continents, and whose Torrance campus sits 20 minutes from Los Angeles International Airport.

She has personal experience with infertility, and says so openly as the reason her communication style leans toward explanation rather than comfort.

Professional Affiliations

Board-certified by the American Board of Obstetrics and Gynecology in Obstetrics and Gynecology and in Reproductive Endocrinology and Infertility. Active in the American Society for Reproductive Medicine and the International Society for Stem Cell Research, with conference presentations at both. UCLA-trained across all four stages of her education and clinical training. Medical Director of Reproductive Partners Medical Group’s South Bay campus, part of a SART-member practice (clinic ID 2254) operating a CAP-accredited embryology laboratory inside the Ivy Fertility network.

Suitable For

• Patients whose history has already produced failed cycles: the physician who carries program-level responsibility for the reporting those cases appear in
• Families using donor eggs or a gestational carrier: third-party paths that run through California’s surrogacy statutes
• Armenian- and Spanish-speaking patients who want a consultation without an interpreter in the room
• Anyone who wants the lab explained: culture day, biopsy timing, PGT platform, and what a result does and does not tell you
• International patients sequencing monitoring around a single Southern California trip
