Sperm survival test could make IVF safer by spotting toxic lab tools

This study checks whether a test using human sperm can reliably detect toxic chemicals in the plastic dishes and tubes used for in vitro fertilization (IVF). Researchers will compare sperm movement after contact with different batches of IVF supplies. The goal is to see if this simple test can replace or supplement the current mouse embryo test, helping clinics avoid materials that might harm embryos.
