These colorful blue spots are actually sperm developing inside the testis of a male mouse. Pictures of growing sperm structure reveal how an omega-3 fatty acid, docosahexaenoic acid (DHA), contributes to sperm development. This work builds our understanding of how DHA acts in the body, leading to new insights into Alzheimer’s disease, diabetes, and the development of a male contraceptive.
