As a result of evolution, various finfish species have developed different breeding strategies. However, there are some similarities, and one of them is the positive effect of ovarian fluid on spermatozoa. The opposite of this phenomenon was found in the common barbel (Barbus barbus). The present study analyzed the effect of ovarian fluid (OF), distilled water (DW) and Woynarovich solution (WS) on the motility, longevity and kinetics of barbel spermatozoa. These spermatozoa parameters were also evaluated with various dilutions of ovarian fluid (OF) in relation to distilled water [0:4 (Group OF 0%), 1:3 (Group OF 25%), 1:1 (Group OF 50%), 3:1 (Group OF 75%), 4:0 (Group OF 100%)] and spermatozoa reactivation after a 30 s (Group OFR30s 100%) treatment in ovarian fluid. The motility analysis was carried out using computer-assisted semen analysis (CASA). The negative interaction of ovarian fluid with spermatozoa motility in the same fish species was recorded for the first time. In pure ovarian fluid, the average spermatozoa motility (MOT) decreased significantly (1.40 ± 0.94%). The negative effect of ovarian fluid-to-spermatozoa motility was reversible, and after a 30 s treatment in ovarian fluid and later dilution with water, spermatozoa motility was reactivated (from 2.25 ± 0.53% vs 69.78 ± 6.02%). The use of Woynarovich solution as an activator of spermatozoa movement had a positive effect (P < 0.05) on spermatozoa movement longevity (motility up to 90 s) and the percentage of motile spermatozoa compared to distilled water (up to 45 s) and ovarian fluid (P < 0.05).

抑制卵巢液对普通须鳉精子活化及精子动力学特性的影响

作为进化的结果,各种有鳍鱼类已开发出不同的育种策略。然而,也有一些相似之处,其中之一是卵巢液对精子的积极作用。在常见的触须(Barbus barbus)中发现了与这种现象相反的现象。本研究分析了卵巢液 (OF)、蒸馏水 (DW) 和 Woynarovich 溶液 (WS) 对触须精子的运动性、寿命和动力学的影响。还使用与蒸馏水相关的各种稀释卵巢液 (OF) [0:4 (0% 组)、1:3 (25% 组)、1:1 (50% 组)] 来评估这些精子参数, 3:1 (Group OF 75%), 4:0 (Group OF 100%)] 和在卵巢液中处理 30 秒(OFR30s 组 100%)后精子再激活。使用计算机辅助精液分析(CASA)进行运动分析。首次记录了同一鱼类的卵巢液与精子活力的负相互作用。在纯卵巢液中,平均精子活力(MOT)显着降低(1.40 ± 0.94%)。卵巢液对精子运动的负面影响是可逆的,在卵巢液中处理 30 秒并随后用水稀释后,精子运动被重新激活(从 2.25 ± 0.53% 对 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。首次记录了同一鱼类的卵巢液与精子活力的负相互作用。在纯卵巢液中,平均精子活力(MOT)显着降低(1.40 ± 0.94%)。卵巢液对精子运动的负面影响是可逆的,在卵巢液中处理 30 秒并随后用水稀释后,精子运动被重新激活(从 2.25 ± 0.53% 对 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。首次记录了同一鱼类的卵巢液与精子活力的负相互作用。在纯卵巢液中,平均精子活力(MOT)显着降低(1.40 ± 0.94%)。卵巢液对精子运动的负面影响是可逆的,在卵巢液中处理 30 秒并随后用水稀释后,精子运动被重新激活(从 2.25 ± 0.53% 对 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。平均精子活力 (MOT) 显着下降 (1.40 ± 0.94%)。卵巢液对精子运动的负面影响是可逆的,在卵巢液中处理 30 秒并随后用水稀释后,精子运动被重新激活(从 2.25 ± 0.53% 对 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。平均精子活力 (MOT) 显着下降 (1.40 ± 0.94%)。卵巢液对精子运动的负面影响是可逆的,在卵巢液中处理 30 秒并随后用水稀释后,精子运动被重新激活(从 2.25 ± 0.53% 对 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。53% 与 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。53% 与 69.78 ± 6.02%)。使用 Woynarovich 溶液作为精子运动的激活剂对精子运动寿命(运动长达 90 秒)以及与蒸馏水(长达 45 秒)和卵巢液相比的活动精子百分比具有积极影响(P < 0.05) (P < 0.05)。
