Clinical correlation analysis of placenta growth factor expression in human seminal plasma and oligoasthenospermia / 第二军医大学学报

ABSTRACT

Objective To explore the correlation between placental growth factor (P1GF) expression and sperm quality in seminal plasma, and to evaluate its clinical significance in patients with oligoasthenospermia and azoospermia. Methods A total of 88 patients undergoing seminal fluid detection were enrolled from the Department of Reproductive Medicine Center of Changhai Hospital of Second Military Medical University fromSep. 2014 to Nov. 2014. The patients were divided into three groups according to the test results: ten cases with normal semen (normal group), 68 cases with oligoasthenospermia (oligoasthenospermia group), and ten cases with azoospermia (azoospermia group). Semen samples from five patients with normal semen and 5 patients with oligoasthenospermiawere collected and assayed for cytokine-related proteinmicroarray. The contents of P1GF in seminal plasma were detected by ELISA. The correlations between P1GF concentration and the sperm concentration and activity in seminal plasma and the age of patients were analyzed by Pearson correlation analysis. Results The contents of P1GF in seminal plasma in the normal group were significantly higher than that in the oligoasthenospermia and azoospermia groups (P<0. 05). The level of P1GF in seminal plasma was related to the concentration and activity of sperm (r=0.362, 0.253; P<0.05), but not to the age of patients. Conclusion The levll of P1GF in seminal plasma is correlated with the sperm concentration, providing reference for diagnosis and treatment of oligoasthenospermia and azoospermia in clinic.
