This image shows the structure of developing spermatids. During sperm development in the testes, a protein called acrosin (shown in green) is released in small packages called vesicles, which fuse to form a single large vesicle called the acrosome. When the omega-3 fatty acid docosahexaenoic acid (DHA) is absent, the acrosome does not form, resulting in a complete loss of matured sperm. This discovery contributes to our understanding of how DHA acts in the body.
