Growing egg and sperm-like cells in the lab to find causes of infertility

Project II

NIH-funded research Magee-Women's Res Inst and Foundation · NIH-11194433

What this research studies

If you take part, researchers will turn patient cells (like blood or skin) into induced pluripotent stem cells and then use a transcription factor method to make primordial germ cell–like cells in the lab. They will test genetic variants found in people with infertility—especially men with non-obstructive azoospermia—to see which changes interfere with germ cell development. The team combines mouse model data with human cell screening to increase speed and reduce false positives from computer-only predictions. The goal is a scalable platform that helps identify which variants actually cause infertility so clinicians can give clearer diagnoses.

Who could benefit from this research

Good fit: Best matches are people who have had genetic testing for infertility—particularly men diagnosed with non-obstructive azoospermia or anyone with variants of unknown significance in genes expressed in germ cells.

Not a fit: People whose infertility is due to physical blockage, reversible lifestyle factors, or who lack suspected germ-cell genetic variants are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could lead to faster, more accurate genetic diagnoses for infertility and help guide future targeted treatments.

How similar studies have performed: Prior mouse experiments and early human cell studies show the basic approach can work, but large-scale, transcription factor–driven human screening of infertility variants is relatively new.
