This article proposes an unusual mechanism of muon structurogenesis in which the particle is formed with the involvement of antimatter. When positrons (antimatter) and electrons (matter) combine, they create particles more complex than positronium. Despite its apparent paradoxical nature, this mechanism has allowed for the discovery of the law of muon structurogenesis. Fundamental muon constants have been obtained from the law of muon structurogenesis. These muon constants have not been obtainable within the framework of the standard model. The muon structurogenesis mechanism predicts the existence of numerous new particles that have not yet been detected. The muon structurogenesis mechanism also predicts the mass spectrum of elementary particles. The proposed structurogenesis mechanism is a general mechanism for all elementary particles, from positronium to the proton. It is a universal mechanism of synthesis in nature. The fallacy of the concept of matter predominance over antimatter in the modern Universe is demonstrated. From the law of muon structurogenesis, it follows that the violation of lepton number conservation is not related to the symmetry or asymmetry of matter and antimatter in the modern Universe. The non-conservation of lepton number and baryon number occurs even under complete symmetry between matter and antimatter.
