Sperm Grown in a Dish

Researchers make sperm that successfully produces offspring in mice—a development that could one day help infertile men.

In a significant step toward combating male infertility, researchers at Yokohama City University have grown mouse sperm in a dish and used the sperm to produce pups that were themselves fertile in adulthood.

Researchers started with small fragments of tissue containing sperm stem cells, called spermagonia, collected from the testes of baby mice. They then grew those cells into functional sperm, using various chemicals to simulate the natural environment of the testes. The results of the study, published in this week’s issue of Nature, may eventually benefit infertile men and boys undergoing chemotherapy.
