Preserving Your Fertility Through Egg Freezing in 2017

Too often, I hear stories of women who have been turned down by fertility clinics because they are difficult patients. These women have been declined based on their advanced reproductive age and/or poor prognosis for achieving a successful pregnancy through IVF treatment. At New Hope Fertility Center in NYC, age is never a discriminating factor for my patients.Why is this important? We do not boost our high IVF pregnancy success data by rejecting patients based on strict criteria. Taking on very difficult patients and helping them overcome their infertility encompasses the overall goal of our One Good Egg Policy. Here, we are committed to treating all patients suffering from infertility – regardless of their diagnosed difficulty. Bottom Line: To get pregnant successfully, only one good egg and one healthy sperm is needed.

New Trends in Egg Freezing

In recent years, egg freezing parties are being sponsored by many fertility clinics. Fertility specialist reach out to women wanting to know more about the medical phenomena of egg freezing to preserve their future fertility. Potential patient are invited to a social party where they will be educated and informed about the benefits of egg freezing.

Candidates for Egg Freezing

It’s very important to realize that egg freezing is not just beneficial to young women in their 20s. Today, many women in their late 30s or early 40s have successfully frozen their eggs.

These women were blessed with a baby when they decided the time is right for them to get pregnant. I recommend women take action to freeze their eggs in their mid to late 30s for the best chance of a successful pregnancy in their 40s.

Successful pregnancies achieve the highest rates when eggs are thawed and transferred to the patient within five years. However, oocytes can be frozen indefinitely.

As the Medical Director for New Hope Fertility Center, I see many women considering egg freezing in their late 30’s and early 40’s.

Important Facts To Stress About Egg Freezing

  • In addition to the cost of medications and procedure fees, patients incur yearly storage costs
  • Most women who are able to afford to freeze their eggs are professional, career-oriented women in their 30’s
  • Egg freezing requires you to maintain a healthy lifestyle, just as though you were planning an imminent pregnancy
  • Studies show that smoking can decrease egg quality and limit the chance of a future successful pregnancy by up to 50 percent
  • Second hand smoke also adversely affects a woman’s egg quality
  • Alcohol and caffeine can cause birth complications for a number of reasons
  • Women should be a place in their life beyond their partying days when they decide to freeze their eggs

Vitrification Method of Freezing Eggs

As one of the first American fertility specialists to offer egg freezing, I helped to pioneer the vitrification process of cryopreserving oocytes. Through the vitrification method of cryopreservation, I have accomplished over 400 live births using this cutting-edge technology.

Look: Vitrification is an advanced technique designed to increase the chance of a successful pregnancy being achieved through fertility preservation. Vitrification is the rapid freeze method of cryopreservation. Extreme, rapid freezing avoids the formation of harmful ice crystals between cells.

Why is this important? The vitrification method increases the chances of pregnancy.

How Vitrification Works

Preparing an egg, embryo, ovarian tissue graft, or sperm sample for rapid freezing via vitrification entails:

  • Placement in a high concentration of cryoprotectant solution while at room temperature
  • Being directly plunged into liquid nitrogen to immediately drop the temperature in a large number of degrees
  • Implementing an extreme rapid rate of thawing to prevent damage to cells


Vitrification is a flash-freezing method preventing the formation of ice crystals between cells. Ice crystals can cause damage.

  • Cryoprotectants remove surplus water
  • 6°F (37°C) to 320°F (-196°C) temperature drop instantaneously
  • 99% survival rate
  • Safely restores cell back to its original state
