The secretory products of Trichomonas vaginalis decrease fertilizing capacity of mice sperm in vitro

Abstract: Trichomonas vaginalis infection is one of the most prevalent sexually transmitted infections in humans and is now recognized as an important cause of infertility in men. There is little information about the effect of extracellular polymeric substances (EPS) from T. vaginalis on sperm, but previous reports do not provide a conclusive description of the functional integrity of the sperm. To investigate the impact of EPS on the fertilizing capacity of sperm, we assessed sperm motility, acrosomal status, hypo-osm… Show more

“…vaginalis infection can impair the reproductive success of men and women since it is associated with the occurrence of pelvic inflammatory disease [4,5] and can reduce sperm viability [6]. The parasite is also associated with premature rupture of membranes, preterm labor, and low birth weight [7,8].…”

“…В log-фазе роста проводили сбор Trichomonas vaginalis с последующей однократной промывкой сбалансированным солевым раствором Хенкса (HBSS) (NaCl 2. Отмытые T. vaginalis ресуспендировали в 1,0 мл HBSS (до концентрации 1,0·10 7 /мл) и инкубировали 60 мин при 37 °С (для максимального накопления продуктов секреции патогена) [13,15,16].…”

“…При экспериментальных исследованиях, прове-денных J. Roh и соавт. [15], были получены убеди-тельные доказательства токсического влияния про-дуктов секреции T. vaginalis на мышиные спермато-зоиды: по сравнению с контролем наблюдалось дву-кратное снижение общей подвижности сперматозо-идов, почти трехкратное снижение количества ак-тивно подвижных сперматозоидов, почти двукрат-ное ухудшение показателей HOS-теста.…”
