Abstract:
The spermatozoon has classically been seen only as a paternal DNA transporter into the oocyte, thus underestimating the entire contribution of the male gamete to the embryo development. The advancement of the research supports that not only the sperm genome, but the entire sperm transcriptome and proteome carry crucial information for fertilization and embryo development. Altogether, 6871 proteins have been reported in spermatozoa so far. Their functional analysis has recently addressed to the sperm proteome a role in fertilization, preimplantation embryo development and paternal epigenetic inheritance. Targeted analysis of human spermatozoa is warranted to compile an evidence-based list of sperm-carried molecular targets in infertile patients.

Spermatogenesis
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
