This thesis was circulated on social networks, in particular on telegram channels broadcasting pro-Kremlin rhetoric. Reports say that the Ukrainian military is freezing male seeds using a cryopreservation method. As the authors of the messages explain, this is all planned to “breed the army of Ukrainians with a high level of russophobia”.

Analysts of the VoxCheck investigated this case, who found out that since 2014, cryopreservation has become popular among Ukrainian military personnel. After the start of a large-scale invasion, the number of applicants increased. Some clinics offer free cryopreservation for the military. However, there is no confirmed data, due to which it is possible to “breed” a whole “army” of Ukrainians with an increased level of russophobia. This is a conspiracy theory of Russian propaganda, since the cryopreservation method does not bring out a “special type of people”, but freezes male spermatozoa in liquid nitrogen for further artificial insemination “in vitro”.

The storage of frozen spermatozoa is not limited in time. For the most part, the freezing of male sperm is associated with the “in vitro” fertilization procedure. This is a specific method of treating infertility, that is, in vitro fertilization. However, cryopreservation is advised to be carried out before chemotherapy and operations that can affect the reproductive function of a person. Cryopreservation can be performed not only for men, but also for women (egg freezing).
