Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation. Sometimes the best way to understand a biological process is to ...

Studying sex from just the male perspective misses half the experience. But much of what we know about the origins of reproductive cells comes from looking at sperm and egg formation separately—or ...

Sometimes the best way to understand a biological process is to disrupt the normal process and analyze the result. That's why Sloan Kettering Institute (SKI) researchers used a strain of mutant mice ...
