Discovery of universal animal sperm gene may lead to male birth control

sea anemone, which solidified the theory that Boule's originated around the dawn of animals around 600 million years ago. This also means that Boule is essential to what it means to be an animal.


Researchers tested the importance of Boule by removing it from a mouse. The animal seemed normal in every way except for his inability to produce sperm. The fact that Boule has remained constant throughout the evolution of so many animals implies that a male animal born without it will be unable to produce offspring.  Understanding Boule and how it works will be essential in treating some forms of male infertility and discovering a medicinal male birth control.

While genes vary from person to person, let alone between species and animal kingdoms, one sex-specific gene has been found in nearly all animals life, remaining unchanged for 600 million years.

A study published in  PLoS Genetics by the Northwestern University Feinberg School of Medicine  found that the gene, Boule, appears to be the only gene exclusively required for sperm production.  The gene was found in all types of animals: mammals, fish, insect, and worms. The gene was even located in one of the most primitive creatures, a
