Abstract

PURPOSE

To investigate the effects of IVF aspiration on the temperature, pH, and dissolved oxygen of bovine follicular fluid.

METHODS

The temperature was monitored at various positions in an aspiration kit. Dissolved oxygen and pH were measured before and after aspiration.

RESULTS

The temperature of follicular fluid dropped by 7.7 +/- 1.3 degrees C upon aspiration. Dissolved oxygen levels rose by 5 +/- 2 vol.%. The pH increased by 0.04 +/- 0.01.

CONCLUSIONS

The temperature change was attributed mainly to evaporation of fluid in the collection tube. Changes in dissolved oxygen levels and pH were due to contact with air. Standard vacuum-based aspiration may induce changes in follicular fluid, which could be detrimental to oocyte health and affect attempts to correlate chemical characteristics with oocyte quality.

摘要

目的

研究体外受精抽吸对牛卵泡液温度、pH值和溶解氧的影响。

方法

在抽吸试剂盒的不同位置监测温度。在抽吸前后测量溶解氧和pH值。

结果

抽吸时卵泡液温度下降7.7±1.3摄氏度。溶解氧水平上升5±2体积%。pH值增加0.04±0.01。

结论

温度变化主要归因于收集管中液体的蒸发。溶解氧水平和pH值的变化是由于与空气接触。基于标准真空的抽吸可能会引起卵泡液的变化，这可能对卵母细胞健康有害，并影响将化学特征与卵母细胞质量相关联的尝试。
