OvaNet: Global Ovarian Tissue Cryopreservation Network

About Us

OvaNet is a global initiative uniting experts in ovarian tissue cryopreservation (OTC) to standardize procedures, improve outcomes, and provide fertility preservation solutions worldwide.

Standardizing freezing and transplantation protocols
Improving the success rates of ovarian tissue preservation
Enhancing follow-up care for patients
Establishing a global registry for clinical data
Collaborating with leading fertility organizations

Our goal for OvaNet is to make sure that we provide OTC to the patients who benefit the most, and that we make the procedures as effective as possible.

The Need for OvaNet

For the past 25 years, various centers worldwide have conducted OTC and ovarian tissue transplantation (OTT) with their own protocols. However, there is no standardization in:

Freezing protocols
Transplantation procedures
Cryoprotectants, media, equilibration times, and temperature profiles
Surgical approaches for transplantation
Reporting of reproductive outcomes

The lack of standardization makes it difficult to compare success rates and evaluate the effectiveness of different techniques. Live birth rates from OTC currently range from 18-41%, highlighting the need for a unified approach.

A Global Iniciative

It is time to unite all our knowledge, expertise, and experience!

It is crucial that we involve both clinical professionals and laboratory scientists in OvaNet, as the initiative aims to address numerous aspects of ovarian tissue cryopreservation and transplantation from both perspectives.

27 countries

Already on-board!

111 Institutions

Inclusive

We want to include small and large centers worldwide!

Centered communication

Aiming to ensure inclusivity, clear governance, and effective working groups

Together we can:

Standardize reporting of reproductive outcomes
Perform subgroup analysis according to diagnosis and age of the patients
Identify determining factors affecting the succes rates
Discuss consensus regarding cryopreservation and transplantation techniques
Improve the efficacy of freezing and transplantation protocols

...and much more!
