Yes, even fruit flies can become sexually frustrated.
A study by researchers from the University of Michigan revealed that male fruit flies who received sexual signals from females and couldn’t mate were more stressed, experienced decreases in fat storage and were less resistant to starvation.
All of the maladies experienced due to sexual frustration also shortened the life span of the male fruit flies. However, successful mating partially offset the negative symptoms.
“These data may provide the first direct evidence that aging and physiology are influenced by how the brain processes expectations and rewards. In this case, sexual rewards specifically promoted healthy aging.” – Scott Pletcher, Senior Author
In a related study, fruit flies who were denied sex chose to imbibe on food spiked with alcohol over non-alcoholic food.
It sounds like all males run into the same sets of problems, regardless of species.
