A Woman’s Body May Incorporate DNA From The Semen Of Casual Sex Partners

Compelling new scientific research has shown that female insects and mammals are able to absorb foreign DNA throughout the cells of their bodies. In human beings, this phenomenon has been conclusively shown to occur in women during pregnancy where genetic material from her growing fetus becomes fused within areas of her brain, affecting her chances of developing Alzheimer’s disease.
The evidence now shows that female animals can incorporate sperm DNA from her prior sex partners. This foreign DNA winds up in future children after the woman successfully reproduces with a completely different male. In the human world, this means that the children a man has with a promiscuous woman could possess genes from previous sexual partners he has never seen or met.
There are existing sociological studies that show a marriage is far more likely to fail when a woman had more than two prior sexual partners (1, 2, 3, 4), but now renewed support for the once-questionable field of telegony is showing that there are also genetic reasons not to start a family with a promiscuous woman: children you have with her may have their gene pool polluted by her random affairs and one-night stands.

Telegony is an idea first proposed by Aristotle that claims offspring can inherit genes from the mother’s previous sexual partners. This idea was not scientifically supported until evidence piled up of microchimerism, the phenomenon of foreign DNA becoming incorporated into the genome of an individual. This was first noted to happen in the case of blood transfusions. If you have received blood while in a state of trauma, your donor’s DNA can become incorporated into your genome. Surprisingly little research has been done on microchimerism since then, but all signs point to this being a widespread and common genetic phenomenon throughout the animal kingdom.
A groundbreaking study on flies last year showed the process of females incorporating DNA from previous male partners and then exhibiting that male DNA into future spawn they had with completely different males.
Scientists at the University of New South Wales discovered that, for fruit flies at least, the size of the young was determined by the size of the first male the mother mated with, rather than the second male that sired the offspring.

“Our new findings take this to a whole new level – showing a male can also transmit some of his acquired features to offspring sired by other males,” she says. “But we don’t know yet whether this applies to other species.”

Dr Stuart Wigby of the Department of Zoology at Oxford University added: “The principle of telegony is theoretically possible for pretty much any internally fertilising animal, but these hasn’t historically been much evidence for it.
Scientists involved in the study are making the guess that sperm DNA gets absorbed into female eggs without fertilizing them:
