Ejaculate samples for male infertility screening

ABSTRACT: The problem of the male reproductive system has both medical and social importance. It is highlighted that spermatozoa or seminal plasma are suitable samples for proteomic analysis of the male reproductive system. We suggested that the ejaculate could serve as one of the analytic specimens to determine fertility, which obtainable with relative ease and which contains many proteins. Moreover, the testis-specific proteins could form the basis of protein panel for detecting disorders associated with male infertility. The current study aimed to examine the ejaculate proteome compared to the spermatozoa and seminal plasma proteomes to determine a panel of proteins that can be used to assess sperm quality. Our results showed that the ejaculate represented a productive source for understanding the male reproductive physiology and could serve as a potential origin for the identification of novel protein biomarkers related to spermatozoa function in infertile. We believe that proteomic analysis based on testis-specific proteins of ejaculate along with spermatozoa (or even instead) can be useful for distinguishing the fertile, sub fertile, and infertile men.

Problems with the male reproductive system are of both medical and social significance. As a rule, spermatozoa and seminal plasma proteomes are investigated separately to assess sperm quality. The current study aimed to compare ejaculate proteomes with spermatozoa and seminal plasma protein profiles regarding the identification of proteins related to fertility scores. A total of 1779, 715, and 2163 proteins were identified in the ejaculate, seminal plasma, and spermatozoa, respectively. Among th ...[more]

Project description:Male factors account for approximately 40% of all infertility. Conventional semen analysis focus on seminal physicochemical property and spermatozoa morphology. They yield no information concerning the functional competence of the spermatozoa(Petrunkina et al., 2007). Owning to the essential role of proteins in the reproductive process, comprehensive and systematic identification of proteome is critical to gain new insights into spermatogenesis and infertility. Recent advances in mass spectrometry have allowed the identification of hundreds to thousands of protein in spermatozoa(Oliva et al., 2008; Amaral et al., 2014; Codina et al., 2015). In major domestic mammalian species, global spermatozoa proteomic profiles have been described in rodents(Baker et al., 2008a; Baker et al., 2008b) and bovine(Peddinti et al., 2008). Meanwhile, lacking of new protein synthesis in spermatozoa supports the current view that the regulation of sperm maturation is controlled by exogenous proteins(O'Rand et al., 2011) (e.g., during epididymal transit). Among the seminal plasma proteins, The human seminal plasma has been comprehensively described (Pilch and Mann, 2006; Batruch et al., 2011; Milardi et al., 2012; Milardi et al., 2013; Sharma et al., 2013). In domestic animal species, some studies performing a systematic analysis on using high throughput proteomics have been performed(Kelly et al., 2006; Moura et al., 2007; Souza et al., 2012; Druart et al., 2013; Soleilhavoup et al., 2014). Buffalos (Bubalus bubalis) are adapted to hot–humid tropical climatic conditions, but have low reproductive efficiency. The low sperm motility maybe contributed to protein components variation of spermatozoa and seminal plasma. The composition of buffalo spermatozoa and buffalo seminal plasma (BSP) remains unknown. Proteomic study would be beneficial to the elucidation of the roles of sperm and BSP proteins in regulation of maturation, motility and fertilization. As such, the aim of the current study was to extensively characterize the differentially expressed protein of buffalo spermatozoa and seminal plasma using a comparative proteomics.
