Most birds mate with the males balancing on top of the females and touching cloacas in a "cloacal kiss"; this makes forceful insemination very difficult. The phallus that male waterfowl have evolved everts out of their bodies in a clockwise coil and aids in inseminating females without their cooperation. These structures make it harder for males to achieve intromission.

The clockwise coils are significant because the male phallus everts out of their body in a counter-clockwise spiral; therefore, a clockwise vaginal structure would impede forceful copulation.

Studies have shown that the longer a male's phallus is, the more elaborate the vaginal structures were. This reduced the likelihood of fertilization by unwanted aggressors in favor of fitter mates.

A number of invertebrate species have independently evolved the mating technique of traumatic insemination where the penis penetrates the female's abdomen, thereby creating a womb into which it deposits sperm.

This has been most fully studied in bed bugs. Some millipedes have penises. In these species, the penis is simply one or two projections on underneath the third body segment that produce a spermatophore or sperm packet. The act of insemination, however, occurs through specialized legs called gonopods which collect the spermatophore and insert it into the female.

The male copulatory organ of various lower invertebrate animals is often called the cirrus.
