Meet Dr. Sergio C. Oehninger, MD, PhD

Dr. Sergio C. Oehninger comes to Sher Fertility Institute New York as a reproductive endocrinology & infertility specialist who has been practicing for over three decades. He has held the prestigious title of the Director of the Division of Reproductive Endocrinology and Infertility (REI) at The Jones Institute for Reproductive Medicine (the first IVF clinic in America). He has helped thousands of couples achieve their dreams of starting a family though IVF and other technologies.

Dr. Sergio C. Oehninger shares his perspective of why he came to Sher Fertility Institute New York and some information on him both professionally and personally.

What made you decide to come to Sher Fertility Institute New York so far from home in Virginia?

As far as patient experience, clinical results, and overall national and international reputation, it does not get better than the Sher Fertility Institute New York. When I met with Dr Tortoriello. I found him to be a man of the highest integrity, knowledge, and dedication to his patients, and I immediately knew this was where I wanted to take my thirty year career to the next level. I was also very impressed by the administration and nursing personnel, as well as its incredible location and facilities. I knew right away this was the team I am destined to join.

What do you like most about what you do?

What I have done during my career has been to help infertility couples achieve their dreams of starting a family. My work has resulted in delivery of over five thousand babies, considering ART and non-ART treatments.

I have witnessed an amazing increase in pregnancy rates in IVF in the last three decades, the result of multiple factors including better hormonal preparations, improved IVF laboratory quality control and assurance, new culture media, and better embryo transfer techniques.

I would obviously like to see all couples succeeding with IVF, and we can certainly be very proud of very high rates of pregnancy in couples with favorable prognosis.

In practice, what are you most proud of?

I am proud when my patients come back after completion of their therapy to “show off” their babies. I have had amazing patients throughout the years, but I can chose a couple that delivered healthy triplets in the late 80s (not a desired outcome, something not happening nowadays as we only transfer 1-2 embryos); the parents of the children have sent me pictures of the three offspring every single year for the last 22 Years at Christmas time, including college graduations and lately a wedding of one of them! An immense reward that keeps motivating me.

Why did you choose to work in the field of reproductive medicine?

I initially chose the specialty of Obstetrics and Gynecology as I considered it a wonderful field that combines endocrinology, surgery, and all the medical conditions affecting pregnancy. With time I elected REI as I learned more about the exciting and new evolving field of IVF. Nowadays I remain absolutely convinced about IVF efficiency and safety.

What do you consider your special areas of interest in reproductive medicine and why?

I am known as in “infertility doctor” that can take care of both members of the couple:  as a female reproductive endocrinologist and as an experienced “andrologist”, i.e., someone taking care also of the male patients in the initial stages of their work up.

What is your approach to patient care?

My approach is simple: to offer a friendly environment where the infertile couple can undergo diagnosis and treatment in a personalized manner and with cutting edge, state-of-the-art- techniques.

At the Sher Fertility Institute New York, it will be based on a multi-disciplinary approach provided by a formidable team of highly qualified reproductive endocrinologists, nurses and laboratory personnel, with psychological and genetic counseling as appropriate.

I am also very sensitive to the financial aspects of IVF and ART in general, and the financial stress added to the infertile women and men.  I am pleased that Sher Fertility Institute New York offers the Attain program as well as has many financing partners to assist patients.

Share something unique people don’t know about you.

I was born in Montevideo, Uruguay. Small and tranquil country, politically and economically relatively stable. Well known for its soccer (actual the real name is football…), with several world championships under their belt. Of course I played soccer in my early days, but kept contact with my local team after moving and becoming a US citizen 30 years ago. I am enjoying watching the World Cup, an event that will somehow “paralyze” the world for a couple of hours every day for the next month!

Tell us about your family? 

Maria is my wife of 42 years (!!!), and is my right and left hand. She is an instructor of political sciences, and interested in political and liberal arts, so she is thrilled about our move to NY City.

Our grown up children are Sergio (commercial litigation lawyer in DC), Sebastian (who works for a non-profit patients’ advocacy institution in Hampton VA), Natalia (a labor and contract lawyer in Dallas, married to Tony, also a lawyer working in real estate), and Matthew (chief financial officer at a law firm in Northern Virginia).

There seems to be some “family deviation” towards law, maybe genetic (many lawyers in my wife’s family) (as opposed to more physicians on my side).

Natalia and Tony gave us our two precious grandchildren, Adriana (30 months) and Anthony (5 months) that we cherish and idolize. Matthew and wife Sami have two of our two family furry babies: Daisy and Lily, and Natalia and family love their Dexter.

What do you do for fun in your spare time? What are your hobbies?

Besides watching international soccer and PGA, I like to golf. But I learnt late in life and sometimes the little ball does not obey my command. I religiously try to go to the gym 3-4 times a week.
