Dr. Tomer Singer, MDTomer Singer, M.D., is board certified in Obstetrics and Gynecology &  Reproductive Endocrinology and Infertility by the American Board of Obstetrics and Gynecology. Dr. Singer joined The Center for Human Reproduction in 2012 following his residency training at Lenox Hill Hospital and subsequently completing his subspecialty training in Reproductive Endocrinology and Infertility at the Weill Cornell Medical College in Manhattan.

Dr. Singer earned his Bachelor of Medical Science and Doctor of Medicine Degrees, as well as the Dean’s honor award, from The Sackler School of Medicine. Dr. Singer completed his residency in Obstetrics and Gynecology at Lenox Hill Hospital in Manhattan.

Dedicated to delivering the best patient care through cutting edge technology, Dr. Singer honed his skills at Lenox Hill, performing hundreds of surgeries that emphasize minimal invasiveness (hysteroscopic and laparoscopic). Dr. Singer also led a team of 12 physicians at Lenox Hill as a chief Ob/Gyn resident. There, he received several awards, including the Best Teacher Award, Best Resident Research Award, and the John O. Vieta Best Resident Award.

Dr. Singer completed his subspecialty training at the Weill Cornell Medical College in Reproductive Endocrinology and Infertility. While he was there, he researched several areas of interest including egg donation, preimplantation genetic diagnosis/screening, minimally invasive gynecological surgeries, and improving IVF success rates.

Several societies have awarded Dr. Singer high honors, such as the American College of Ob/Gyn Resident Research Award, the ASRM Resident Reporter Travel Award, and the John M. Thorp Research Award. He has authored multiple research publications, and presents at both domestic and international conferences concerning issues related to diminished ovarian reserve, minimal surgery techniques, PGD, fertility preservation, IVF stimulation protcols, and egg donation.

Dr. Singer is a Fellow of the American College of Obstetrics and Gynecology. His other professional affiliations include active membership in the Society for Reproductive Endocrinology and Infertility (SREI), the Society of Gynecological Investigation (SGI), the American Society for Reproductive Endocrinology (ASRM), the American Association of Gynecological Laparoscopists (AAGL), the Endocrine Society and the New York State Medical Society.

Dr. Singer serves at Hofstra North Shore LIJ School of Medicine as an assistant Professor. There, he is a devoted mentor to residents and medical students and enjoys contributing to the education of future physicians.

A new study supports what many doctors have observed for decades — that women with thyroid disorders can experience serious reproductive problems.

Dr. Tomer Singer, a reproductive endocrinologist at the Center for Human Reproduction notes that “For over two decades now, we have noticed a strong link between hypo- and hyperthyroidism and infertility as well as adverse pregnancy and neonatal outcomes.

Thyroid disorders can prevent patients from ovulating and is one of the leading causes of irregular menstrual problems,” Singer explained. “The treatment is simple and safe and results in resumption of the menstrual cycle within weeks.

The increased risk of multiple births has been known for decades. In the past several years there has been a significant decline in the rate of higher order multiple births, partly, thanks to revised ASRM guidelines for the recommended number of embryos to be transferred in an IVF cycle.

Single embryo transfer is rapidly gaining grounds in most programs, especially for younger patients. However, a significant proportion of embryo transfers in the US in 2014 still involve the transfer of more than one embryo. This is more common with older patients, especially given the high rate of chromosomally abnormal embryos (which rises exponentially beyond age 40).

A second culprit is the fact that IVF is not covered by many insurance providers. The significant out-of-pocket expense of IVF drives patients to pressure their physicians to transfer two embryos (or more) to increase their chances of becoming pregnant.

The good news is that the solution is within reach and should focus on four aspects, which we have been practicing at Lenox Hill Human Reproduction and the Center for Human Reproduction at North Shore-LIJ Health System:

  1. Having continuous dialogue with law makers and insurance providers to promote coverage for ART procedures, and especially for IVF with an emphasis on single embryo transfer.
  2. Encouraging patients to freeze their eggs in their early 30’s when most eggs are “healthy,” which will allow for single embryo transfer later in life when they are ready to conceive (even if they are in their late 30’s or early 40’s).
  3. Improving egg and embryo freezing techniques in the lab, which will allow all IVF centers to be able to offer single embryo transfers while saving the surplus embryos for potential future transfers.
  4. Promoting genetic testing of embryos prior to their transfer back to the uterus – a technique called PGS (Preimplantation Genetic Screening) and transferring a single, chromosomally normal embryo (free of Down’s Syndrome and other abnormalities), thus reducing multiple birth rate with its exorbitant cost to healthcare, and increasing the chance of delivering healthy babies, one at a time.

DW In-Tomer logoDr. Singer, Director of our Egg Freezing Program, sheds light on how fertility preservation can help endometriosis patients.


I have been working with Dr. Seckin for over a decade now, and could not agree more that endometriosis is a disease that’s under-researched and that patients with endometriosis should be treated in parallel for both their debilitating pelvic pain and for their inevitable impending infertility. Endometriosis, though benign, is known to affect patients’ uterus, ovaries, fallopian tubes and other pelvic organs crucial for successful pregnancy and a healthy delivery.

A good strategy to tackle this condition and provide patients with the highest level of care would be an inter-disciplinary approach to treating endometriosis while preserving their fertility. I would advise young single patients with endometriosis to be proactive and consider freezing their eggs before this chronic medical condition reduces their fertility and conception potential. With improvements in the egg freezing technology in the past three years we can now offer endometriosis patients hope and the chance of starting a family.

If you have concerns about endometriosis and how this affects your fertility, please schedule an appointment with myself or one of my colleagues to get expert advice on treatment options.

A new “do-it-yourself” ultrasound method could let women who are undergoing in vitro fertilization (IVF) cut down on their trips to the doctor’s office, a new study suggests.

I’m all in favor of doing monitoring at home; I just don’t think that this study proves that doing it in all patients is feasible.

In 2012, the American Society for Reproductive Medicine (ASRM) said egg freezing through vitrification should no longer be considered experimental.

Since that announcement, fertility specialists say they’ve seen much more interest in egg freezing. Dr. Tomer Singer, director of the Egg Freezing Program at North Shore LIJ Center for Human Reproduction, estimates that before 2012, his clinic saw about five to 10 patients interested in egg freezing per year. Now, he gets the same number of inquiries on a weekly basis.

Dr. Singer says the new process could increase interest as it is perfected and the cost comes down. Currently, the cost of egg collection can range from about $5,000 to more than $15,000, depending on where women have the procedure done and how many eggs they freeze.
