Seminal plasma represents a unique environment for maturation, nutrition, and protection of male germ cells from damaging agents. It contains an array of organic as well as inorganic chemicals, encompassing a number of biologically and immunologically active compounds, including hormones. Seminal plasma contains also various pollutants transferred from outer environment known as endocrine disruptors. They interfere with hormones at the receptor level, act as inhibitors of their biosynthesis, and affect hormone regulation.In this minireview, the main groups of hormones detected in seminal plasma are summarized. Seminal gonadal steroids were investigated mostly with aim to use them as biomarkers of impaired spermatogenesis (sperm count, motility, morphology). Concentrations of hormones in the seminal plasma often differ considerably from the blood plasma levels in dependence on their origin. In some instances (dihydrotestosterone, estradiol), their informative value is higher than determination in blood.Out of peptide hormones detected in seminal plasma, peptides of transforming growth factor beta family, especially antimullerian hormone, and oligopeptides related to thyrotropin releasing hormone have the high informative value, while assessment of seminal gonadotropins and prolactin does not bring advantage over determination in blood.Though there is a large body of information about the endocrine disruptors' impact on male reproduction, especially with their potential role in decline of male reproductive functions within the last decades, there are only scarce reports on their presence in seminal plasma. Herein, the main groups of endocrine disruptors found in seminal plasma are reviewed, and the use of their determination for investigation of fertility disorders is discussed.
