Sperm RNA: a New Class of Fertility Biomarkers for Birds

Abstract

Leeuwenhoek discovered and named spermatozoa but could not convince the scientific world the potentiality of the sperm. Similarly, transcriptionally quiescent genetic material was marked by a state of tranquil among researchers until the breakthrough of RNA transcript residing inside the sperm. Even though, queries and enigmas highlight throughout sperm research, most reports favor us in thinking about role of these transcripts in fertilization and early embryonic development. Many sperm transcripts have been confirmed as bio–fertility marker in human and other mammalian specie. With this review, we are attempting to summarize spermatozoal work conducted so far in other vertebrate classes and thus representing a potential to serve as bio–fertility marker through such a non–invasive approach in birds.
