About
The IVF program at UCSF Center for Reproductive Health runs with two directors at the top — Dr. Marcelle Cedars is one of them, alongside Dr. Mitchell Rosen. She also directs the division of Reproductive Endocrinology at UCSF, a role that puts her between the research bench and the exam room: her stated job is to keep individualized patient care and scientific investigation pulling in the same direction.
Her own research targets two questions that define much of modern fertility care: how ovarian age affects not just conception but women’s overall health, and what long-term health looks like for children conceived through assisted reproduction. Clinically, she sees the whole endocrine span — from hormonal problems in adolescence through PCOS and complex endocrine disease to perimenopause — with particular depth in ovarian aging, uterine anomalies and recurrent pregnancy loss.
Cedars earned her MD at the University of Texas Southwestern Medical School in 1981, trained in obstetrics and gynecology at Parkland Memorial Hospital, and completed her reproductive endocrinology fellowship at UCLA in 1987. She is certified by the American Board of Obstetrics and Gynecology.
Clinical Expertise
- Ovarian aging and reserve: Professional assessment of diminished ovarian reserve and premature ovarian insufficiency, with individualized family-building plans by age and diagnosis
- PCOS across the lifespan: Ovulation induction, metabolic evaluation and long-term health monitoring from adolescence to perimenopause
- Complex endocrine infertility: Thyroid disease, elevated prolactin and adrenal disorders occurring alongside infertility
- IVF program leadership: Co-directs the center’s IVF program with Dr. Rosen, setting protocol and quality standards
- Recurrent pregnancy loss and uterine anomalies: Workup and management of anatomic and endocrine causes of repeated loss
Why Choose Dr. Marcelle Cedars
She sets the standards she practices under. As division director and IVF program co-director, the protocols used at one of the country’s leading academic fertility centers are built under her oversight.
Ovarian aging is her research, not just her referral base. Few clinicians study the question she answers daily — what ovarian age means for fertility and for a woman’s health overall — as a named research program.
One physician across decades of hormones. Her scope runs from teenage endocrine problems to menopause management, which matters for patients whose fertility questions cannot be separated from their general hormonal health.
She follows the children. Her published research on the long-term health of ART-conceived offspring addresses the question many patients quietly ask before starting treatment.
