On Monday, July 8, Callista Mulder, Ans van Pelt, and Geert Hamer of the Reproductive Biology Laboratory (LVV) hosted a group of 15 prominent Japanese clinicians and scientists, including Katsuhiko Hayashi and Takashi Shinohara, both pioneers in the field of in vitro gametogenesis.

While some attended the ESHRE conference on human reproduction, embryology, and gynecology, others visited the Vrolik Museum with Geert Hamer.

Following this, a mini-symposium on potential innovations and collaborations to preserve the fertility of prepubertal children undergoing gonadotoxic (cancer) treatment was held. Presentations were given by Katsuhiko Hayashi, Takashi Shinohara, Masahito Ikawa, about the possibilities and risks of in vitro gametogenesis and large genetic screens.

Rod Mitchell, Ieva Masliukaite, and Andreas Meissner presented the current progress on male and female fertility preservation in our clinics. The discussions highlighted the mutual learning opportunities and the potential for future collaborations to make safe fertility preservation for childhood cancer survivors a reality.
