An estimated 17% of all couples worldwide are involuntarily childless (infertile). The clinically identifiable causes of infertility can be found in the male or female partner or in both. The molecular pathophysiology of infertility still remains unclear in many cases but is increasingly being revealed by genetic analyses. ⋯ Genetic causes, disease patterns, and the related investigations are becoming increasingly important in the diagnostic evaluation of infertile couples and have implications for further treatment, for the children of the affected couple, and for other family members.

Sarcopenia is a progressive, generalized disease of skeletal muscle characterized by a loss of muscle strength and muscle mass. The combination of obesity and sarcopenia is called sarcopenic obesity. Because of the aging of the population in many countries around the world, sarcopenia and sarcopenic obesity are a challenge for global health policy. ⋯ A targeted and structured approach to the detection and treatment of sarcopenia and sarcopenic obesity can make a major contribution to the maintenance or improvement of these patients' functionality and quality of life.
