ABSTRACT
<p><b>OBJECTIVE</b>To investigate the pathogenesis of hematospermia syndrome using the rat model of hemospermia induced by partial ejaculatory duct obstruction.</p><p><b>METHODS</b>Fifty male rats were divided into Groups A (n=20) and B (n=30), the former subjected to incomplete ligation of the right ejaculatory duct, while the latter open-close sham operation. Electro-stimulation was performed for ejaculation induction one week after the operation. Those that developed hematospermia in Group A were chosen as Group A1, while those with normal ejaculation in Group B included in Group B1. The semen indexes and seminal vesicle pressure were compared between Groups A1 and B1.</p><p><b>RESULTS</b>Compared with Group B1, Group A1 showed significantly decreased semen volume (P < 0.01), lower sperm motility (P < 0.01) and higher seminal vesicle pressure (P < 0.01), but no statistically significant differences were observed in the WBC count and sperm density in the semen between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>Hemospermia syndrome can be induced by partial ejaculatory duct obstruction, with changes of semen indexes, and it is closely correlated with high seminal vesicle pressure.</p>
