Because seminal plasma contains factors which inhibit the fertilising ability of spermatozoa,
it is essential that spermatozoa be separated from it quickly and efficiently. Four basic …

The onset of clinical assisted reproduction, a quarter of a century ago, required the isolation
of motile spermatozoa. As the indication of assisted reproduction shifted from mere …

For assisted reproduction technologies (ART), numerous techniques were developed to
isolate spermatozoa capable of fertilizing oocytes. While early methodologies only focused …

Fertility potential of semen depends upon the presence of viable and motile spermatozoa. A
variety of techniques has been reported whereby motile spermatozoa are separated from …

Methods of separating motile human spermatozoa avoiding centrifugation have been
described 1–3. Ejaculated semen is deposited in contact with the culture medium, and then …

OVERVIEW e aim of sperm preparation for assisted reproduction technology (ART) is to
maximize the chances of fertilization to provide as many normally fertilized oocytes as …

A modified swim-up procedure for the selection of motile and morphologically normal
spermatozoa is described. Applied to abnormal (astheno and asthenoterato) semen …

To compare standard density gradient/centrifugation sperm preparation with a novel non-
centrifugation-based dual-chamber capillary dish in efficiency for motile human sperm …

We compared the pregnancy rates and sperm characteristics of semen prepared by the
albumin, Percoll, Puresperm, and swim-up methods. Semen analysis was performed by a …

A simple and atraumatic method for concentrating washed, motile spermatozoa from normal
and subnormal semen specimens is described. It incorporates a modified technique of …
