To compare the number and quality of spermatozoa recovered following the standard centrifugation method with those recovered following oscillation of the relative centrifugal field during the centrifugation method.
Prospectively controlled in vitro study.
Private andrology laboratory.
PATIENT(S): Seventeen healthy sperm donors.
INTERVENTION(S): Equal halves of the same semen sample were evaluated following the standard centrifugation or following oscillation of the relative centrifugal field during centrifugation.
MAIN OUTCOME MEASURE(S): Number of sperm, sperm motility, progressive sperm motility at 0 hours and after 3-hour of incubation at 5 degrees C in TES and Tris (buffer) (TEST)-yolk.
RESULT(S): The number of sperm, sperm motility, progressive sperm motility at 0 hours and after 3-hour of incubation at 5 degrees C in TEST-yolk were significantly higher for the sperm recovered following oscillating centrifugation compared with standard centrifugation.
CONCLUSION(S): Oscillating the relative centrifugal field during centrifugation yields higher number of viable spermatozoa.
比较标准离心法回收的精子数量和质量与离心过程中相对离心场振荡后回收的精子数量和质量。
前瞻性对照体外研究。
私立男科学实验室。
17名健康精子捐献者。
对同一精液样本的等分样本分别采用标准离心法或离心过程中相对离心场振荡法进行评估。
精子数量、精子活力、在0小时以及在5摄氏度下于TES和Tris(缓冲液)(TEST)-卵黄中孵育3小时后的渐进性精子活力。
与标准离心法相比,振荡离心后回收的精子在0小时以及在5摄氏度下于TEST-卵黄中孵育3小时后的精子数量、精子活力、渐进性精子活力均显著更高。
离心过程中振荡相对离心场可产生更多有活力的精子。
