Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
Not shortly after Roger Maris record was broken, another baseball player, Jason Giambi and various other athletes were either suspected of, or proven to have, taken anabolic steroids. Again, Congress convened a hearing, and just as they did the first time in 1990, they did not determine that steroids were a danger, but rather that the danger was more in protecting professional sports organizations.

Lactones contribute significantly to the flavor of fruit, and of unfermented and fermented dairy products,  and are therefore used as flavors and fragrances.  Some examples are γ-decalactone (4-decanolide), which has a characteristic peach flavor;  δ-decalactone (5-decanolide), which has a creamy coconut/peach flavour; γ-dodecalactone (4-dodecanolide), which also has a coconut/fruity flavor,  a description which also fits γ-octalactone (4-octanolide),  although it also has a herbaceous character;  γ-nonalactone , which has an intense coconut flavor of this series, despite not occurring in coconut,  and γ-undecalactone .
