Abstract
In classical biology and physiology, our understanding of human reproduction at the cellular level is the fertilizing combination of spermatozoa and ova and the growth and development of the fertilized egg (zygote) from an embryo into a fetus, which are completed within a sterile environment of the reproductive system in the human body.
In recent novel evolution theories, male sperm and female ova as two different eukaryotic cells exist in their unique environment before combination and the relationship between these cellular entities and their environments can be deciphered to be the interaction between them and their environmental evolutionary entities at the same and/or different evolutionary levels.
During the past decades, accumulating evidence has indicated that fertilization and embryonic development cannot occur within a completely sterile environment because bacterial species and subcellular entities including viruses and extracellular vesicles have been found normally in human semen, follicular fluid, and the reproductive tract of men and women.
From the fimpological perspective, the complex interactions occurring between germ cells and their environmental entities at the same and/or different evolutionary levels determine the destiny of a fertilized egg, embryo, and fetus during pregnancy.
