Our mission

To support innovation in fertility treatments in order to help couples and individuals realise their desire to have a child. Thus we are contributing to a new paradigm in fertility treatments, making them accessible to more people.



We are supporting a project that is breaking new ground within the field of fertility treatments. It will be a paradigm shift for people who today have no possibility to have biological children.

The reasons for infertility may be the lack of own sex cells – for example, men with chromosome variation, young boys who have to undergo cancer treatment, or women who are approaching menopause. The technology is currently under preclinical development.

The research group behind Kallistem has been working in the field of infertility for 25 years. The company was established in 2012 and is lead by two internationally recognised experts of reproduction research.
