Physicians and Clinical Team
Kofinas Fertility Group is led by Dr. George Kofinas, a board-certified reproductive endocrinologist with expertise in IVF, recurrent pregnancy loss, and immune-mediated fertility disorders. The practice has built a particular reputation for its approach to immunological contributors to implantation failure and recurrent miscarriage — an area where the scientific debate is active and patient demand for thorough workup is high. The clinical team includes fertility nurses, embryologists, and care coordinators who reflect the diversity of the Brooklyn communities they serve. The practice's scale enables personalized physician-patient relationships of the kind that patients in larger network practices sometimes miss.

Laboratory and Success Rates
Kofinas Fertility Group's embryology laboratory supports full IVF services at the Brooklyn location. The laboratory uses vitrification for egg and embryo cryopreservation, blastocyst culture, and quality protocols designed to optimize embryo development. The practice's emphasis on immunological evaluation extends to protocol decisions around embryo transfer preparation, with individualized endometrial management for patients with prior implantation failures. Patients should review the most current cycle-level data published by the CDC's ART Surveillance program and the SART Clinic Summary Report.
Patient Experience
Kofinas Fertility Group Brooklyn occupies a position in New York's fertility landscape that is distinct from both the large Manhattan clinic chains and small satellite offices. It is an independent, physician-led practice in one of New York's most populous boroughs, serving a community that has historically had to travel to Manhattan for specialist fertility care. Reviews describe a practice where physician access is meaningful — patients feel they are interacting with their doctor, not just a rotation of covering physicians — and where the immunological evaluation is thorough for patients with prior failures.
The Third Avenue location is easily reached by subway on the 2/3, 4/5, or B/Q lines (Atlantic Avenue–Barclays Center station), making it one of Brooklyn's most transit-accessible fertility clinic addresses. Citi Bike stations are nearby, and the Atlantic Terminal area has abundant bus service as well. Parking is available in the surrounding neighborhood but transit access is a key practical advantage for non-driving Brooklyn patients.
The Brooklyn patient community is one of New York City's most diverse, and Kofinas Fertility Group reflects that diversity — serving patients from across the borough's many communities with varied cultural, linguistic, and religious backgrounds. The practice welcomes LGBTQ+ patients and single parents by choice.
Considering At-Home Insemination?
Not every fertility journey begins in a clinic. At-home intracervical insemination (ICI) is a lower-cost, private option that suits patients with no known fertility diagnosis — including single parents by choice, same-sex couples, and people who want to try a few cycles before committing to clinical treatment.
At-home insemination kits like those from MakeAMom come with step-by-step instructions designed for donor or partner sperm. Kits are a one-time purchase that can be reused until conception succeeds, require no clinic visit, and arrive in plain, discreet packaging. Many patients use them as a first step while working toward a fertility consultation — or alongside ovulation tracking while they wait for an appointment slot.
If you have a known fertility diagnosis, have been trying for 12 months without success (six months if you're over 35), or your physician has already recommended IUI or IVF, a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
New York's fertility insurance mandate requires most state-regulated fully-insured employer health plans to cover IVF and related fertility treatments. Kofinas Fertility Group's financial team assists patients with benefit verification, prior authorization, and out-of-pocket projections. Brooklyn patients should confirm whether their employer plan is state-regulated (subject to the mandate) or self-insured under ERISA (not subject to the mandate). For patients without adequate coverage, financing through healthcare lending partners is available.
