Relationship between Helicobacter Pylori and Male Infertility / 中山大学学报(医学科学版)

Helicobacter pylori （H.pylori） is a gram-negative， spiral-shaped bacillus and it is the only bacteria known in medicine that can live in the stomach， with a high infection rate in the population. Besides its confirmed link to peptic ulcer and chronic gastritis， H.pylori has recently been found to be associated with many extragastric diseases， including male infertility. The incidence of male factor infertility keeps rising， but some reasons remain unclear. This paper summarized the research on H.pylori and infertility abroad in recent years in order to speculate and explore the possible relationship between them.
