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 ...

In vitro reconstitution of mouse germ cell development makes it possible to convert mouse pluripotent stem cells into primordial germ cells, which go on to generate functional sperm in vivo.

Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual reproduction. Two novel hypotheses have been proposed that ...

Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilized gametes and thrive without males. In a study ...

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 ...

There are those, politicians, pundits and even a few scientists, who maintain that whether our bodies make ova or sperm are all we need to know about sex. They assert that men and women are defined by ...

Pluripotent stem cells (PSCs) can make all the tissues including gametes such as sperm and eggs. Researchers report a robust method for the generation of gametes from PSCs using the body of rats that ...

In most living animals, egg cells are vastly larger than sperm cells. In humans, for example, a single egg is 10 million times the volume of a sperm cell. In a new study, Northwestern Engineering ...
