Abstract

Male infertility is a growing global public health concern. Thus, it is relevant to investigate the causes of male fertility decline and understand the consequences not only for the individual affected by male fertility decline but also the family unit and society. Causes of male fertility decline include mechanical, systems disturbances, genetic, diet, lifestyle, and environment. Consequences are far-ranging–affecting individuals, families, local societies, and population groups–with global ramifications. Formulating awareness of the causes and consequences of male fertility decline is fundamental to stimulate more specific research regarding this urgent global health issue and the prevention and treatment of male fertility decline.
