Telegony is a theory of heredity holding that offspring can inherit the characteristics of a previous mate of the female parent; thus the child of a woman might partake of traits of a previous sexual partner.
Autopsies on women who have had two or three husbands have demonstrated DNA from husbands 1 and 2 in her tissues, including brain tissue.

Recently, human semen was shown to contain cell-free nucleic acids, such as DNA, long single stranded RNA, and small RNAs–miRNA and piRNA. Here we demonstrate that human seminal plasma contains a variety of cell-free dsRNAs and discuss the potential biological roles of these molecules in inheritance. dsRNA plays a role in a variety of biological processes, including gene regulation, is extremely stable and can gain access to cells from the extracellular medium. We suggest that one of the possible functions of dsRNA in human seminal plasma may be to influence human oocytes and therefore, influence the offspring.

Once deemed heretical, emerging evidence now supports the notion that the inheritance of acquired characteristics can occur through ancestral exposures or experiences and that certain paternally acquired traits can be ‘memorized’ in the sperm as epigenetic information. We discuss how sperm transmits paternally acquired phenotypes by shaping early embryonic development.

Revisiting telegony: offspring inherit an acquired characteristic of their mother's previous mate
Newly discovered non-genetic mechanisms break the link between genes and inheritance, thereby also raising the possibility that previous mating partners could influence traits in offspring sired by subsequent males that mate with the same female (‘telegony’). ...

Double Stranded RNA in Human Seminal Plasma
Recently, human semen was shown to contain cell-free nucleic acids, such as DNA, long single stranded RNA, and small RNAs–miRNA and piRNA. The RNAs have been suggested to have potential biological roles as communication molecules between cells ...

Epigenetic inheritance of acquired traits through sperm RNAs and sperm RNA modifications
