In many species, seminal fluid can be used as a sort of mating plug.

Larger mating plugs were less likely to be removed.

The male of this species employs a mating plug.

The giant spermatozoon is thought to have evolved in this manner so as to act like a mating plug.

These mating plugs are used to prevent the female from mating with other males.

The study found that mating plugs had no effect on female nutrition and serve as an enforcement device against rival males.

Upon completion of the act, the penetrating partner will seal off the recipient's genital region with a mating plug.

The broken palps serve as mating plugs, which makes future matings with a mated female more difficult.

However, the study found no evidence to support the hypothesis, as males were able to displace the mating plugs of other males.

One is that traumatic insemination is an adaptation to the development of the mating plug, a reproductive mechanism used by many species.

"They'd already rigged up a mating plug to match the fuel plug on the Pak ship.

In response to this polyandry, the female produces mating plugs of her own to prevent too many males from copulating with her.

There is typically a single spring-loaded contact at the side of the opening, so some variation in mating plug barrel diameters can be accommodated.

These mating plugs are placed within the female cloaca instantly after copulation, which was hypothesized to function as a "chastity belt."

Like in rats, following copulation the male seals the female's epigyne with a mating plug, preventing the female from further mating.

Mating plugs are used by many species, including several primates, bees, rats, reptiles, squirrels, scorpions, mice, and spiders.

The mating plug of T.s. parietalis is a jellylike blob produced by males that is implanted within the females reproductive tract.

The spermatophore of Cressida cressida is modified into an external mating plug known as a sphragis (plural sphragides).

Although this species of fruit flies (Drosophila hibisci) found success in mating plugs, they are ineffective for other Drosophila species.

The mating plugs of Drosophila hibisci are gelatinous, hard composites that adheres to the uterus of the female in the event of copulation.

The sockets and mating plugs are defined in the ANSI/SAE J563 specification.
