East Coast Fertility's Mount Sinai location, at 701 Route 25A, Mount Sinai, NY 11766, brings specialized reproductive medicine to the North Shore of Suffolk County, Long Island. Route 25A is one of the key east-west corridors of Long Island's North Shore, and the Mount Sinai address serves patients from Port Jefferson, Stony Brook, Miller Place, Setauket, Coram, and surrounding communities who want a quality fertility practice without the commute to Nassau County or Manhattan. East Coast Fertility holds a 5.0-star rating and is listed in the New York fertility clinic directory. New York's strong fertility insurance mandate makes coverage for IVF and related treatments available to many Long Island patients.
Physicians and Clinical Team
East Coast Fertility at Mount Sinai is staffed by fellowship-trained reproductive endocrinologists who are board certified in Reproductive Endocrinology and Infertility. The East Coast Fertility physician group has an established presence on Long Island and brings experience treating the full range of infertility diagnoses, from straightforward ovulatory dysfunction to complex cases involving endometriosis, diminished ovarian reserve, and recurrent pregnancy loss.
The North Shore Suffolk County community is served by Stony Brook Medicine's academic health system, and some fertility patients at East Coast Fertility may have prior obstetric or gynecological care through Stony Brook Hospital — a familiarity that can ease care coordination. East Coast Fertility's physicians maintain active ASRM membership and participate in ongoing continuing education in stimulation protocol refinement, preimplantation genetic testing, and endometrial evaluation.
The clinical team includes reproductive nurses experienced in IVF cycle management, cycle coordinators for monitoring logistics, and financial counselors who can help Long Island patients navigate New York's insurance mandate requirements. The Mount Sinai team is familiar with the North Shore community and the specific access considerations — ferry schedules from Connecticut, LIRR connections — that affect patients in this part of Long Island.

Patient Experience
The Route 25A address in Mount Sinai places East Coast Fertility at the center of a North Shore Suffolk community that is growing steadily in population and in the density of young professional and family households. Parking is available on-site, and the location is easily reachable from the Veterans Memorial Highway and Route 347 corridors that connect central Suffolk County with the North Shore.
Patients on the North Shore of Suffolk County have historically had limited local fertility care options — most major Long Island fertility programs are concentrated in Nassau County or western Suffolk, requiring substantial commutes for patients from Port Jefferson, Setauket, or Stony Brook. East Coast Fertility's Mount Sinai location addresses this geographic gap directly.
The practice's five-star rating reflects high patient satisfaction with both clinical quality and the personal, accessible care experience. For North Shore Suffolk families navigating a fertility journey, having a trusted local practice — rather than commuting 45 minutes to an hour each way for monitoring appointments — can meaningfully reduce the logistical and emotional burden of treatment.
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 State has a robust fertility insurance mandate requiring large-group health plans to cover medically necessary fertility treatments, including IVF, for eligible patients. Long Island patients with employer-sponsored coverage through large New York employers are among the most likely in the country to have meaningful IVF coverage.
Patients at East Coast Fertility Mount Sinai should verify their coverage by contacting their insurer's member services department before beginning treatment. The clinic's financial counselors can assist with benefit verification, prior authorization, and discussion of any out-of-pocket responsibilities. For patients with limited coverage, financing through medical lending programs is available.
