摘要
Semen analysis, as stated by the World Health Organization, is the only accepted tool to assess male fertility. However its predictive value to assess male capacity to initiate a pregnancy is limited. With the introduction of IVF (especially via intracytoplasmic sperm injection), infertility caused by diminished sperm production is frequently solved, but knowledge of sperm physiology remains very poor. Moreover, a percentage of males with apparently normal semen are unable to impregnate healthy women. Therefore, improvements in the diagnostic tools to assess male fertility potential are necessary. The aim of this review is to describe sperm molecular factors implicated in male fertility, demonstrated by their role in sperm physiology, the molecular differences found between fertile and infertile males, or by their influence oil the results obtained in assisted reproduction treatments in terms of embryo quality and pregnancy achievement. From a search and objective evaluation of the currently available evidence, it is concluded that there is no unique factor able to predict male fertility, but several molecular factors are involved in sperm function and can potentially be considered as fertility markers. In this context, a complex molecular tool designed to analyse a battery of parameters seems to be necessary.
