Sperm Metabolism Breakthrough Could Transform Infertility Treatments
Overview: A Molecular Switch Powers Sperm’s Final Sprint Researchers at Michigan State University have identified a molecular “switch” that ramps up sperm energy just before fertilization. This discovery sheds light on how sperm metabolize glucose and other fuels to enable the rapid, high-energy movement needed to reach and fertilize an egg. The work, conducted in…

Chromium and Health: Is It an Essential Nutrient or Just a Belief?
Chromium in nutrition: essential or not? Chromium is a bright, ordinary metal known for its use in fittings and appliances. In nutrition, it appears in the form of trivalent chromium (Cr3+) and is sold as a dietary supplement. Companies claim it can boost athletic performance and help regulate blood sugar, but eight decades of research…
