“Gamete donation in the time of DNA surprises”
In 2022, Cryos organized a stakeholder workshop to better address and understand the challenges new technologies present in relation to the anonymity of donors and donor-conceived children.

“Experiences and attitudes of Danish men who were sperm donors more than 10 years ago; a qualitative interview study”
A collaborative study between Cryos International and the universities of Aarhus, Aalborg, Ghent, and Sheffield sought to investigate how former sperm donors thought and felt about having been sperm donors in the past.

“Attitudes of Sperm Donors in Denmark and the United States”
In 2021, Cryos carried out a study – the first of its kind – comparing the opinions of ID Release and Non-ID Release donors on several different topics.

“Sperm depositors during a global pandemic”
During the 2020 pandemic, Cryos International experienced an increase in men wanting to deposit their sperm. This led to an investigation on the motivation of depositors during the COVID-19 pandemic.

With more than 35 years of experience, Cryos has the highest number of registered pregnancies worldwide and the largest selection of carefully screened donors.
We are very satisfied with Cryos as a partner. We are particularly pleased with the positive and quick response that we receive from Cryos’ service minded staff. In addition, they always appear very helpful and professional, which is important to us when choosing.
