摘要
This study aimed to compare the effects of polypropylene (PP), lightweight PP (UP) and expanded polytetrafluorethylene (e-PTFE) hernia mesh on the reproductive function of adult male Sprague-Dawley (SD) rats following open tension-free hernioplasty. Forty adult SD rats were obtained and divided into five groups: A sham-operated (FO) group, an e-PTFE mesh group, a PP mesh group, the UP mesh group and a normal control (NC) group (without any surgical manipulation). Ninety days following open tension-free hernioplasty, hematoxylin and eosin staining and immunhistochemistry were used to observe the pathological changes of the testicular tissue and to compare the expression of hypoxia-inducible factor-1 alpha (HIF-1 alpha) in the rat testis, respectively. ELISA was used to analyze the serum concentration of antisperm antibodies (AsAbs) and routine semen testing was conducted to measure the percentage of grade a+b sperm from the epididymis. More than 50% of mesh adherence to the spermatic cord was observed in the PP and UP groups, and mild or no adhesion was observed in the NC, FO and e-PTFE groups. In the UP and PP groups, marked congestion of necrotic tissue was observed in the seminiferous tubule cavity, a significant reduction in the percentage of grade a+b sperm and a significant increase in the expression levels of AsAbs and HIF-alpha. It was concluded that the e-PTFE mesh exhibited a marginal effect on the reproductive function of rats compared with that of the PP and UP mesh and is more suitable for tension-free hernioplasty. The clinical significance of these results requires further elucidation with a multi-centered prospective study.
