Abstract：
PURPOSE:Our purpose was to compare the number and quality of spermatozoa recover following the standard centrifugation method with those after pulsing the relative centrifugal field during centrifugation. METHODS:A prospectively controlled in vitro study using ejaculates from 10 healthy sperm donors was undertaken. Number of sperm and sperm motility at 0, 3, and 24 hr post-incubation at 5 degrees C in TEST-yolk results determined the efficacy of the centrifugation techniques. RESULTS:The number of sperm and sperm motility at 0, 3, and 24 hr post-incubation at 5 degrees C in TEST-yolk were significantly higher for the sperm recovered following pulse centrifugation compared with those after standard centrifugation. CONCLUSIONS:Pulsing the relative centrifugal field during centrifugation yields a higher number of viable spermatozoa.

临床试验,杂志文章abstract：PURPOSE:A large part of infertility treatment involves the use of exogenous gonadotropins. The last decade has seen a progressive switch from human menopausal gonadotropin (hMG), the original gonadotropin product, to progressively more costly products, primarily or exclusively containing follicle-stimulating hormone (F...
