Females that have recently been inseminated start kicking away their suitors or, when harassed, extend their egg-laying tube, which blocks access to the vagina. They even begin exuding a scent that renders tall musle teen woman unattractive.

All this is induced by semen components that end up in her bloodstream. Usually, females prefer to have multiple fathers for a clutch of eggs—to generate healthy genetic diversity. The whole process is akin to leaving a mental mating plug. It is present in the semen but also sticks to the tails of the sperm cells.

For up to seven hours, the initial shot of sex peptide causes females to give males the cold shoulder. Sex peptide is only one of the multitude of chemical compounds in semen that a female banana fly receives each time she mates with a male.

What do the rest do? Well, research in other insects can give us an inkling of what such substances might be capable of. Another substance, the protein PSP1, is ejaculated by the male corn earworm moth into his mate and there immediately shuts down the production of pheromones, meaning that other males which totally rely on scent can no longer find her.

The appearance of carbon dioxide bubbles inside the spermatophore then forces out the sperm and other contents into the female.

This list makes one wonder whether some of the many proteins in human semen could also have such manipulative effects. If they do, then this would be one way to explain the results of a study by Gordon Gallup and Rebecca Burch.
