Procedure allows women to freeze eggs to preserve future fertility

30.01.2006


Researchers at the Yale Fertility Center are now offering a cutting edge reproductive procedure called oocyte cryopreservation that allows women to freeze their eggs and use them at a later time to conceive a child.



Pasquale Patrizio, M.D., professor in the Department of Obstetrics, Gynecology & Reproductive Sciences and Director of the Yale Fertility Center, is introducing this technique at Yale in collaboration with an oocyte cryopreservation expert from Bologna, Italy. They will also be researching ways to improve the success of the technology.

Oocyte cryopreservation is aimed at three particular groups of women: those diagnosed with cancer who have not yet begun chemo- or radiotherapy that is toxic for oocytes; those undergoing treatment with assisted reproductive technologies who, for personal reasons, do not consider embryo freezing; and those who do not have a partner and would like to preserve their future ability to have children.


Preparation for oocyte cryopreservation includes consultation, evaluation, and instruction on the use of fertility medications to increase the number of naturally produced eggs. The patient is monitored throughout this outpatient procedure.

Patrizio said the currently reported overall success rate is around two to three babies born per 100 eggs preserved. Compared to conventional in vitro fertilization with non-frozen eggs--eight to nine babies born per 100 eggs--these rates seem low, but are likely to increase as the technique, which is still considered experimental by the American Society for Reproductive Medicine, is refined. Success also depends on the age of the donor--eggs frozen from women before age 35 have a better chance of producing a successful pregnancy.

For patients with cancer, Patrizio, with the help of Emre Seli, M.D., assistant professor in the Department of Obstetrics, Gynecology & Reproductive Sciences, will work with oncologists to help preserve future fertility in younger cancer patients.

"As in the early days of in vitro fertilization, this procedure is still evolving," said Patrizio. "Embryo cryopreservation as an alternative to egg cryopreservation has a higher success rate, but it is not an option for many women."

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
