IVF in conjunction with egg or embryo cryopreservation technologies ensure today’s woman has ability to be biologically connected to her children in the future. Pregnancy success rates using cryopreservation technology are comparable to those success rates using a fresh eggs and embryos. Major tech companies – Facebook and Apple – have been covering the cost of fertility cryopreservation as part of employment benefits since 2014.

Egg vs. Embryo Freezing

Egg freezing – oocyte cryopreservation – is a phenomenal medical technology available for today’s women to preserve their fertility for tomorrow. These women want to ensure they have the ability to be biologically connected to their children in the future. Embryo cryopreservation – using known or donor sperm – is also becoming increasingly popular as a means for women to preserve their ability to have a family.

Candidates for Fertility Preservation

Egg and embryo freezing is increasingly being sought out by:

  • Today’s modern women who are focused on their education and career opportunities
  • Women whose circumstances in life are not presently conducive to rearing children
  • Women who have not be able to find their life partner
  • Women who are facing cancer treatment – chemo or radiation – that could damage the quality of their eggs and/or destroy their ovarian function by sending them into premature menopause
  • Women who are undergoing IVF and are likely to produce excessive eggs, but have ethical or religious concerns over freezing embryos

Egg Freezing

By preserving their eggs through oocyte cryopreservation, women can postpone motherhood past their prime childbearing years. Pregnancy success rates using a woman’s egg that has been cryopreserved are comparable to success rates using a fresh egg.

The freezing of a woman’s eggs (oocytes) during her prime reproductive years has become increasingly more popular with women in the 21st century. Women are excited about preserving their future fertility through oocyte cryopreservation. The Society for Assisted Reproductive Technology (SART) estimates that 76,000 women will freeze their eggs by 2018 – 15 times that of their counterparts in 2013.

In Vitro Fertilization (IVF)

The egg freezing process begins with the woman undergoing ovarian reserve testing.

Egg freezing is accomplished through a fresh IVF cycle, stopping short of egg fertilization in vitro.

  • Stimulation of a woman’s ovaries using fertility drugs to produce several egg follicles during one fresh IVF cycle
  • Harvesting eggs from the woman’s ovaries through surgical retrieval
  • Preparation and freezing of the eggs for preservation through a process known as vitrification
  • The rapid-freezing technique of vitrification makes it possible to freeze eggs quickly so that ice crystals do not form between cells
  • Freezing tanks and storage for the eggs are on premises at New Hope Fertility NYC

Future Fertility

When the woman is ready to start building her family, the egg freezing process continues.

  • Her eggs are thawed and fertilized in vitro by injecting a single sperm cell into a single egg – Intracytoplasmic Sperm Injection (ICSI)
  • The resulting embryos are cultured in vitro for up to 5 days (blastocyst stage)
  • A predetermined number of quality embryos are transferred into the woman’s uterus for implantation into the uterine lining to achieve pregnancy

Embryo Freezing

Embryo freezing is accomplished through a fresh IVF cycle, stopping short of transferring the resulting embryos into the woman’s uterine cavity. Instead, all resulting embryos are cryopreserved. When the woman is ready to start building her family, the FET process begins.
