Wayne Lin, MD, MPH

About

Dr. Wayne Lin sees patients in English, Mandarin and Taiwanese. That matters more in fertility care than in most specialties, because the decisions here are made from numbers: what an anti-Müllerian hormone result says about your remaining eggs, what a stimulation response of three follicles changes about your protocol, what a 43 percent versus a 12 percent live birth rate per retrieval means for how many cycles you should budget. A interpreter can carry conversation. Carrying a number, a protocol and a risk across three languages in a fifteen-minute visit is a physician’s job, and it is the reason international families and Chinese-speaking patients in Orange County look for him specifically.

The rest of his record is unusual for a private-practice fertility physician. He took his MD at the UCLA David Geffen School of Medicine in 2012, completed obstetrics and gynecology residency at UCSF in 2015, then trained further in reproductive endocrinology and infertility through the advanced fellowship program at Brigham and Women’s Hospital, Harvard Medical School, finishing in 2018, and added a master’s in public health from Harvard. That combination shows up in what he publishes: uterine (Müllerian) anomalies, ovarian aging and fertility preservation — the first two being population-level questions about how often a malformed uterus or a falling egg supply causes infertility, not just technique papers. The American Society for Reproductive Medicine has given him research awards for that work and the North American Menopause Society has honored it, and he chairs sessions and speaks at national and international fertility meetings rather than only attending them. US News lists him among its Best Doctors, a directory built on peer nomination rather than on outcomes, so read it as evidence that colleagues in the field know his name.

He is a network physician of Reproductive Partners Medical Group at Irvine, the practice’s monitoring-only site run with Fertility Centers of Orange County. Daily or every-other-day stimulation scans, bloodwork and dose adjustments happen there; retrieval, fertilization, biopsy and transfer happen at a Reproductive Partners main campus in the practice’s CAP-accredited laboratory. That split is the first thing to confirm with his coordinator, along with how far apart your monitoring date and your retrieval date fall. His stated approach is individualized rather than protocol-first, and his listed focus areas include LGBTQ+ family building and third-party reproduction.

Clinical Expertise

• IVF and infertility treatment: stimulation design, monitoring and transfer planning across the causes of female infertility, with attention to ovulation disorders and declining ovarian reserve
• Fertility preservation: egg, embryo and sperm freezing for patients starting chemotherapy or pelvic surgery on a deadline, and for women pacing family timing, using the practice’s vitrification program
• Genetic diagnosis and PGT: embryo testing for chromosome number and for known single-gene conditions, coordinated with the embryology team that performs the biopsy and an outside genetics laboratory that runs the assay, plus carrier screening before a cycle
• Müllerian anomalies and recurrent loss: septate, bicornuate and otherwise malformed uteri, and the cavity problems that cause repeated implantation failure or second-trimester loss — diagnosis, hysteroscopic and surgical management decisions, and what the anomaly means for carrying a pregnancy
• Third-party reproduction: gestational carrier cycles, donor egg and donor sperm programs, including the California pre-birth order and parentage paperwork those paths require
• Care across languages and borders: evaluation, protocol explanation and cycle records handled directly in Mandarin or Taiwanese, with English documentation for the lab and for records you take home

Why Choose Dr. Wayne Lin

Three languages, and the clinical authority to use them. Language fluency on a physician profile is usually a courtesy line. His is paired with a stated focus on international patients and LGBTQ+ families, and with research in the two areas where the numbers need explaining most — ovarian aging and genetic testing decisions.

A public health degree behind the clinical training. An MD, a Harvard advanced REI fellowship and an MPH is an uncommon combination in a private clinic. Practically, it is the training that reads a SART outcome table for what it says about a specific age band and denominator, instead of quoting the highest number in it.

Published on the causes, not only the techniques. His research covers uterine anomalies and ovarian aging, both of which decide whether a cycle is even worth starting, and both honored by ASRM and NAMS. He also chairs conference sessions, which is a role granted to people whose colleagues expect them to know the literature.

Eleven years since fellowship, at the Orange County end of a Los Angeles group. Training completed in 2018, with the Irvine practice giving Orange County patients monitoring close to home while the laboratory side stays with a program that reported 3,302 cycles in SART’s 2023 national data collection.

Professional Affiliations

American Society for Reproductive Medicine, including research awards; recognized by the North American Menopause Society; listed by US News as a Best Doctor. Advanced fellowship training in reproductive endocrinology and infertility at Brigham and Women’s Hospital, Harvard Medical School, with UCSF residency, a Harvard master’s in public health, and a UCLA medical degree. His Reproductive Partners profile names that training rather than a board certification status, so verify certification with the American Board of Obstetrics and Gynecology if you are weighing it. He practices through Fertility Centers of Orange County at the Irvine monitoring site; Reproductive Partners Medical Group’s SART registration (clinic ID 2254) covers its Beverly Hills, Long Beach and South Bay campuses, and the group’s published outcome figures are reported for that combined registration, not for Irvine.

Suitable For

• Chinese-speaking and international patients who want informed consent, protocol rationale and outcome numbers discussed without a translator between the physician and the answer
• Patients preserving fertility before cancer treatment, where the freeze has to finish before an oncology start date
• Families with a known hereditary condition considering PGT-M, or older patients weighing PGT-A on their own eggs
• Patients told they have a uterine anomaly, or who have lost pregnancies without an explanation
• Intended parents and LGBTQ+ couples building a family through donor gametes or a gestational carrier in California
