The impact of proteins, glycoproteins and fructose in blood and seminal plasma on sperms concentration In infertile men

Abstract EN

Background : proteins, glycoproteins and fructose as parameters used to assess infertility in men. Objective : To determine and correlate serum and seminal plasma of total proteins, glycoproteins and fructose with infertility in men. Patients and Methods : The study was performed on 154 subjects ; 109 infertile men (oligospermic and azoospermic) and 45 normal volunteers (normospermic men).

All sera and seminal plasma were submitted for total proteins, glycoproteins and fructose levels measurment. Results : No significant difference was noted in serum and seminal plasma of total proteins in oligospermic and azoospermic and that of normospermic men (P > 0.05) compared to normospermic men. Statistical significant reduction (P < 0.05) was noted in seminal plasma glycoproteins in oligospermic as compared to normospermic and azoospermic men. A significant elevation (P < 0.05) of fructose levels were observed in seminal plasma of azoospermic when compared to others. Conclusion : This study may indicate that the higher concentration of glycoprotein in seminal plasma the better quality of semen and a significant negative correlation (r =−0.749 : P < 0.05) were observed between seminal plasma fructose and sperm count of infertile men.
