I recently came across the concept of paternal inheritance from previous generations on the internet, and due to my obsessive-compulsive disorder, I am unable to convince myself. Therefore, I am seeking help from a doctor to find answers. Is my understanding correct?…Understanding: Whether in China or abroad, the theory of paternal inheritance from previous generations is an absolutely incorrect concept. Assuming that I have had sexual intercourse with three boyfriends who have had sexual relations with me over the past six years, starting from the age of 18, and none of them wore a condom during our sexual encounters, I have not become pregnant (implying that I am not a virgin and there was vaginal bleeding after one sexual encounter). The sperm and seminal fluid from my first two boyfriends (including but not limited to those ejaculated into my vagina, uterus, even deeper areas, as well as those during oral sex that ended up in my mouth, digestive tract, and face) were naturally completely eliminated from my body within a week of entering it or contacting my external skin. The genetic material in the sperm and seminal fluid would never cause any genetic variation in my maternal cells by assimilation into my maternal cells. The genetic material in the sperm and seminal fluid would never integrate into the endometrial cells of my internal reproductive organs, nor would it guide the endometrial cells of my internal reproductive organs to generate and release chemical toxins to remotely attack my third boyfriend’s sperm when I and my third boyfriend decide to have a child. Therefore, the sperm and seminal fluid from my first two boyfriends would never interfere with or change my body, nor would they interfere with any child we might have after having sexual relations again with my third boyfriend…
