However, the females of most species tend to be larger than the males are, and most males have larger digits -- for grasping females during mating. The best time to determine the sex of a given frog is during the breeding season, when you can observe courting and reproductive behaviors.
Most frogs have internal genitals, and the vast majority of species practice a method of external fertilization called amplexus. During amplexusmales mount females from behind and grasp their midbodies to immobilize them.
The females then release clumps of eggs, over which the male releases his sperm. Obviously, egg laying is a behavior limited to females, but sometimes a male may try to breed with other another male during the chaos of breeding time.
