About
Jenna Friedenthal’s research question was about the embryos nobody wants to transfer. She worked on mosaicism — the mixed chromosome population found in a portion of early human embryos — at a point when the field was still arguing whether those results were biology or laboratory artifact. That work is why PGT-A results land differently on her desk than on most clinicians’: she has done the bench-stage interpretation herself. Two ASRM Resident-In-Training Awards, and a senior research fellowship in medical school, are the training-stage version of the same record.
She trained in New York through four institutions: undergraduate at Yale University, medical degree at Albert Einstein College of Medicine with distinction in research, residency at New York University completed in 2013, and a reproductive endocrinology fellowship at the Icahn School of Medicine at Mount Sinai completed in 2018. She is board-certified in obstetrics and gynecology, a Fellow of the American College of Obstetricians and Gynecologists, and an assistant clinical professor at Mount Sinai.
Her clinical practice is concentrated in preservation and genetics: egg and embryo freezing, IVF with preimplantation testing, and family building for LGBTQIA+ patients.
Clinical Expertise
- Egg and embryo freezing: her first-listed service, for age-related, medical and elective timing
- Preimplantation genetic testing: mosaicism research background, which changes how a borderline PGT-A result is counseled
- IVF with genetic risk management: screening decisions built into cycle planning rather than added afterwards
- LGBTQIA+ family building: donor-based and reciprocal pathways on her listed patient groups
- Reproductive research and teaching: assistant clinical professor at Mount Sinai, with award-recognized resident research
Why Choose Dr. Friedenthal
She researched the gray zone in embryo testing. Published work on mosaicism in the early human embryo, the area where PGT-A results are hardest to interpret.
Twice recognized for research by the specialty’s own society. Two ASRM Resident-In-Training Awards, on top of a medical-school senior research fellowship in reproductive endocrinology and immunology.
Egg freezing is not an occasional case for her. Preservation is her first listed service, and her training path — Einstein research distinction, NYU residency, Mount Sinai fellowship — ran through it.
She teaches at the Icahn School of Medicine as an assistant clinical professor.
Professional Affiliations
Fellow of the American College of Obstetricians and Gynecologists and member of the American Society for Reproductive Medicine, the society whose Resident-In-Training Awards she has won twice. Faculty records list an assistant clinical professorship at the Icahn School of Medicine at Mount Sinai and a Senior Research Fellowship award received in medical school.
Suitable For
- Patients freezing eggs or embryos before starting a family: her first-listed clinical service
- Couples who have had an ambiguous or low-mosaicism PGT result: the interpretation question she researched directly
- LGBTQIA+ patients building a family with donor gametes: a named patient group in her practice
- Anyone who wants the reasoning behind a genetic screening decision: research background in embryo genetics, not just test ordering
