The gene in Japanese rice fish, expressed in the germ cells, provides a molecular cue that prevents the start of sperm formation.
Genetic Technology and Eugenics
Science provides us with powerful tools irrespective of our intentions and entrusts us with the choice to use it effectively.

When the researchers disrupted fox13 in adult fish with two X chromosomes (the female state), sperm formed in the female ovary. These sperm were functional and could fertilize eggs normally.
The results indicated that germ cells in these fish, and potentially other vertebrates, do not need to be in the environment of the male reproductive organ to begin their switch into sperm.
Protein Helps Developing Germ Cells Clean Genetic Imprints
A new study says that a protein called Tet1 is partly responsible for giving primordial germ cells a clean epigenetic slate before developing into sperm and egg cells.

PiRNA Molecules Protects Germ Cells from Damage
A mark of evolutionary success is shown by passing one's genes on to the next generation.

Researches Aimed at Germ Cell Development Should Follow Certain Standards
A team of reproductive biologists have declared that research aimed at developing germ cells—the progenitors of eggs and sperm—in vitro should be held to especially rigorous scientific standards
