Hypoosmotic Sperm Swelling Test: Reevaluation of Its Potential Use
نویسنده
چکیده
The aim of this study was to assess the predictive value of the hypoosmotic sperm swelling test. Good correlations were observed between the percentage of spermatozoa undergoing swelling and the percentage motility both in normal (r = 0.68; p < 0.001) and infertile patients (r = 0.65; p < 0.001). In contrast, sperm swelling did not significandy correlate either with sperm oocyte fusion (assessed by the zona-free hamster egg penetration test) or with the ability of the spermatozoa to penetrate human mid-cycle cervical mucus.

Effect of Seminal Plasma on Hipoosmotic Swelling Test in Fresh Alpaca Spermatozoa
The process of fertilization can’t be attributed only to the number of live, motile and normal sperm deposited within the female but especially to its functionality [1]. The hypoosmotic test or hypoosmotic test (HOST) is a functional test, by which the live sperm are subjected to an incubation in a hypoosmotic solution, the sperm with the functional membrane will allow the entry of water by osm...

OBJECTIVE Sperm preparation techniques select sperm population with improved sperm motion characteristics. We sought to determine whether the swim-up technique selects spermatozoa with the ability to undergo hypoosmotic swelling, and how swim-up and subsequent capacitation affect the acrosome reaction rate. METHODS Semen specimens from 15 normal donors were divided into unprocessed, swim-up, ...

This work aimed to study the correlations between the physical characteristics of semen, sperm morphology and the biochemical integrity of the plasmatic membrane of raw sperm in young Nelore bulls (Bos taurus indicus). A total of 420 bulls between 18 and 22 months of age were examined for breeding soundness according to the criteria established by the Brazilian College of Animal Reproduction. A...
