CORRECT, even SPERM ITSELF (no fetus) has big effects!!!!!

Not too many scientists feel welcome on GA, but I owe it to the community to chime in and say this post is correct.

Weird cell changes from mere sperm effects exist.

Females with NO sons and in fact no embryos of any kind EVER, have DNA in their bodies and brains from Men's SPERM ALONE!!!!

10% of nulligravid (never pregnant) females PROVEN to have male DNA in their bodies in large numbers of cells : sperm DNA up to 20.7 male cells per 100,000 female cells in never-pregnant females from unprotected sex !: refer :

and 2012 other :

The weird mystery RNA fragments delivered by sperm is only now first being mapped, to determine which RNA payloads express proteins and genes and what they might do in invaded primate tissues :

Why do sperm carry RNA? Relatedness, conflict, and control:

"it has become apparent that sperm also carry thousands of different RNAs, and the functions of most of these are UNKNOWN"

the main non-genetic components found in sperm including DNA methylation, chromatin modifications, RNAs and proteins

Sperm RNAs, in particular sperm microRNAs (miRNAs) and tRNA-derived small RNAs (tsRNAs), can mediate intergenerational transmission of paternally acquired phenotypes [epigenetics]

In many animals, seminal fluid alters both the bodies and sometimes even the behaviour of females

Women Store DNA From Every Man They’ve Ever Made Love With, Study Finds
https://neonnettle.com/news/4209-women-store-dna-from-every-man-they-ve-ever-made-love-with-study-finds

paper- 2019 - Nongenetic paternal effects via seminal fluid:

Our findings cast doubt on traditional breeding designs aimed at estimating the genetic effects of fathers on offspring, and challenge our views on the nature of inheritance.

TL/DR : OP video is factual, but RNA from mere sperm is just as alarming
