About
Ben Lannon has done something most fertility physicians have not: he helped push a law through two state legislatures. As a board member of All Paths Family Building and Fertility Within Reach, regional advocacy groups, he took part in passing legislation that widened access to fertility care in New Hampshire and Maine — the same two states his patients come to him from, in person at South Portland or Portsmouth and by telehealth across both. He describes the goal plainly: a day when everyone who needs these services can reach them.
The rest of the profile is a standard academic REI track run out of Boston. Lannon grew up in Exeter, New Hampshire, took his undergraduate degree at Dartmouth College and his medical degree at Brown University, then added a master’s in Evaluative Clinical Sciences from the Dartmouth Institute for Health Policy and Clinical Practice. Residency in obstetrics and gynecology and his REI fellowship were both at Beth Israel Deaconess Medical Center with Harvard Medical School, the fellowship also carrying Boston IVF. He is double board-certified in the two specialties, a Fellow of the American College of Obstetricians and Gynecologists, and teaches at Harvard Medical School and Maine Medical Center.
His research grows directly out of that epidemiology training: he works on prediction models for IVF, including a Fertility and Sterility paper on personalized prediction of first-cycle IVF success and another on individualized multiple-birth risk after double embryo transfer. Clinically he lists LGBTQ family building, patients who have experienced a miscarriage, endocrine disorders that affect reproduction, and surgical treatment to optimize fertility. His stated method with patients matches the statistician’s instinct — break an uncertain process into concrete steps so there is at least a map, even when the destination is not.
Clinical Expertise
- IVF cycle management: full care from stimulation through transfer, using prediction-model evidence to shape first-cycle decisions rather than averaging across patients
- ICSI: micromanipulation fertilization where male factor is part of the picture
- LGBTQ+ family building: evaluation and treatment for same-sex couples, single patients and transgender patients, including fertility preservation; he has spoken publicly at a transgender fertility event in Maine
- Care after miscarriage: evaluation and support for patients who have lost a pregnancy, named as one of his standing clinical interests
- Reproductive endocrine disorders: hormonal conditions that interfere with ovulation and conception
- Surgery to improve fertility: operative treatment aimed at optimizing the chance of conception, alongside the cavity and tubal testing this office performs
- Teaching and research: trains reproductive medicine fellows and residents while publishing on IVF decision-making
Why Choose Dr. Ben Lannon
A physician who has read the coverage rules from the inside. Legislative work on fertility access in Maine and New Hampshire is unusual experience for a treating doctor, and it shows up where patients actually struggle: insurance denials, benefit questions, and deciding what is reachable in a given plan.
Certified twice over, and still practicing locally. Board certification in obstetrics and gynecology plus reproductive endocrinology and infertility, twelve years of Castle Connolly Top Doctor listings from 2014 to 2025, and a practice split between two New England offices rather than a single academic clinic.
His research is about your next cycle. Prediction of first-cycle IVF success and personalized multiple-birth risk after double embryo transfer are decision tools, not bench work. Ask him how he uses them when he proposes a transfer plan.
He holds patients’ experience to a measurable standard. A Healthgrades Outstanding Patient Experience Award for 2022 and 2023, and a Fertility Equity cultural-competency certification through Morehouse School of Medicine, on a roster where the whole center carries that training.
Professional Affiliations
Fellow of the American College of Obstetricians and Gynecologists. Clinical Instructor at Harvard Medical School and at Maine Medical Center, where he teaches reproductive medicine and conducts research. Former board member of All Paths Family Building and of Fertility Within Reach, the two regional groups that campaign for insurance coverage of fertility treatment. His published work appears in Fertility and Sterility, and he has presented nationally. The center he practices in reports its cycles to SART under the network’s Maine registration.
Suitable For
- Patients about to start IVF or ICSI who want protocol and transfer decisions argued from outcome data rather than habit
- Patients who have miscarryed, looking for evaluation instead of a rushed next cycle
- LGBTQ+ patients and couples, including those planning family building before or after transition, treated by a team with cultural-competency certification
- Patients with an endocrine diagnosis getting in the way of conception, where stimulation protocol choice does most of the work
- Maine and New Hampshire residents who would rather open their case by telehealth and monitor locally in South Portland
