Israeli scientists have made yet another breakthrough in treating infertility, this time in men. Researchers from the Technion in Haifa say they have found a way, using sperm from mice, to treat male infertility.

Technion researchers have discovered a new phenomenon where sperm from mice can induce non-reproductive cells from hamsters to fuse and form a syncytia – a cell with multiple nuclei. The scientists conducted a study they say reveals a potential new method to test the capacity of sperm to induce cell fusion, which could be used to diagnose male fertility issues.

The study, published in eLife, finds that the degree of this multinucleation is dependent on the fertilizing potential of the sperm. With further validation, the findings could be used in the development of new diagnostic tools for male infertility.
