Scientists were able to grow sperm in a lab using skin cells

The scientists believe the technique could be used to cure male sterility in the future.

Researchers from the University of Pittsburgh School of Medicine were able to coax human embryonic stem cells (hESCs) and human-induced pluripotent stem cells (hiPSCs) into becoming precursor sperm cells.

“No one has been able to make human sperm from pluripotent stem cells in the lab, but this research indicates it might be possible. This model also gives us a unique opportunity to study the molecular signals that govern the process, allowing us to learn much more about how sperm are made. Perhaps one day this will lead to new ways of diagnosing and treating male infertility,” Dr. Easley said in a press release.
