Contents Pregnancy rates in managed horse populations depend on the innate fertility of the
mares and stallions involved and on the quality of breeding management. Of course …

The hypoosmotic swelling (HOS) test is a relatively new assay used to evaluate the
functional integrity of the sperm's plasma membrane. In fact, more studies have been …

An osmotic resistance test (ORT) was developed for bull semen. Raw semen was incubated
for 40–60 min at 35° C in a fructose/sodium citrate solution with an osmolarity of 150 mOsm …

The objective of this study was to determine the effectiveness of the hypoosmotic swelling
(HOS) test together with the supravital test as a means of evaluating the functional integrity …

Low-density lipoproteins (LDL) have been previously isolated and identified as the
cryoprotective fraction of yolk. The effect of LDL on sperm motility after freezing–thawing has …

Objectives. To test the hypothesis that conventionally used procedures for semen
cryopreservation may cause an increase in the production of reactive oxygen species (ROS) …

Frozen semen specimens from 22 Holstein bulls representing a wide range of field fertility
levels or nonreturn rates (NRR) were used in this study. Semen specimens were thawed at …

Semen samples from 179 infertility patients were analyzed for type and number of white
blood cells (WBC) by a combination of immunologic techniques. Forty-one (23%) had more …

Objective To review recent studies on the development of new tests of human sperm
function and evaluation of which sperm characteristics are most important for fertilization in …

A functional membrane is requisite for the fertilizing ability of spermatozoa, as it plays an
integral role in sperm capacitation, acrosome reaction, and binding of the spermatozoon to …
