'Showy' big beards linked to having smaller testicles
The study explored the link between the sizes of testicles and other physical male attributes linked to mating. Some males of their respective species fight over females. Because of this, the size of their antlers or teeth may be of great relevance. Other alpha males will demonstrate their superiority to others by growing large manes or other attributes specific to their species.
While early models of ejaculate allocation predicted that both relative testes and ejaculate size should increase with sperm competition intensity across species, recent models predict that ejaculate size may actually decrease as testes size and sperm competition intensity increase, owing to the confounding effect of potential male mating rate. A recent study demonstrated that ejaculate volume decreased in relation to increased polyandry across bushcricket species, but testes mass was not measured. Here, we recorded testis mass for 21 bushcricket species, while ejaculate ampulla mass, nuptial gift mass, sperm number and polyandry data were largely obtained from the literature.
Is it sexist to tell a man that the larger his testicles, the more likely he is to cheat on his girlfriend? Could it be misogynistic to suggest that a married man who cheats should not be judged as harshly as a wayward wife? Or, perhaps, no and hopefully not.
