Study Explores How Microgravity Affects Sperm Fertilization in Space
April 28, 2026

Researchers from Australia conducted experiments to simulate microgravity's impact on sperm fertilization using human, pig, and mouse samples. The study, published in Communications Biology, found that while human sperm swimming ability remained unaffected, its navigation was altered. Mice and pig sperm showed reduced fertilization success, raising concerns about reproduction in long-term space missions.
