ANDRADE SOUZA, Fernando et al. IGF-I, Leptina, insulin and proteins associated to seminal plasma qualiy: local action. Rev. Med. Vet. [online]. 2010, n.20, pp.9-25. ISSN 0122-9354.

It is possible that the expression of some elements in seminal plasma, such as proteins and hormones, may act as markers of quality. Several studies have demonstrated an association of seminal plasma proteins with fertility. Among the most studied, there are the proteins with affinity to heparin, which play an important role in sperm capacitation and acrosome reaction. Some endocrine factors and/or locals may be associated with the expression and function of these proteins, aiding in sperm condition conducive to fertilization. Among them stand out as insulin, leptin and growth factor insulin-like type I. These factors may highlight the differences between these animals because they are associated with the metabolic condition and structure of sperm cells, aiding in determining the quality of seminal plasma. Thus, the study of seminal plasma proteins associated with the metabolic condition of these hormones are present in this medium can serve as a new parameter for assessment of male reproductive condition.
