This workshop will explore the in vitro derivation of human gametes (eggs and sperm) from stem cells. Sessions will consider scientific and clinical goals motivating research in this field, technical ...

So you have finally found the partner of your dreams—but no matter how hard you try, no children have come along. Could science offer new answers to mate choice and infertility? For several years, ...

A major transition in evolution is the shift from asexual to sexual reproduction in early organisms. But why would a yeast ...

Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants. In flowering ...

Reprogramming of the epigenome in mammals occurs in both the germline and the early developing embryo. Some regions of the epigenome appear to escape this process. Parentally imprinted genes are not ...

In 2016, two Japanese reproductive biologists, Katsuhiko Hayashi and Mitinori Saitou, made an announcement in the journal Nature that read like a science-fiction novel. The researchers had taken skin ...
