Abstract: Animal genitalia typically exhibit limited size variation relative to overall body size, a pattern known as negative allometry. The ‘one-size-fits-all’ hypothesis suggests that genital compatibility between sexes constrains the evolution of extreme genital sizes, yet… read more here.

Abstract: Abstract The function of insect external genitalia has played a significant role in exploring insect mating mechanisms and male fertilization strategies. However, due to the privacy of genital coupling, insect copulatory mechanisms have only been… read more here.
