A step toward lab‑grown sperm: Scientists turn stem cells into early sperm cells in a mini‑testis
Scientists have successfully transformed human stem cells into early-stage sperm precursor cells using a 'mini-testis' laboratory model. This breakthrough provides a new way to study germline development and could eventually lead to treatments for male infertility.

One of the many causes of male infertility is a failure in germline development, the process by which embryonic cells develop into sperm or eggs. Finding treatments has been challenging because there are no laboratory models that accurately mimic how sperm develop, but a recent study brings us a step closer.
In a recent study published in Cell Stem Cell , scientists presented a recipe for transforming human blood-derived cells into immature primate sperm precursor cells in a mini-testis-like environment.
