Success in cryopreserving stallion semen has been very variable. Several different freezing regimes have been published. However, because extenders and procedures used in each regime have differed, direct comparison of these techniques has been very

In boar spermatozoa, the capacitating agent bicarbonate has been shown to induce rapid changes both in plasma membrane lipid architecture and in motility; in each case, a PKA-dependent pathway is involved. Early bicarbonate-induced changes in protein

Contents Cyclic AMP is known to play a major role in intracellular signalling during mammalian sperm capacitation. However, despite much research, many of the molecular details of cyclic AMP's involvement remain obscure. In this review, I discuss the

Bicarbonate/CO2, a physiological effector of sperm capacitation, has been shown to induce a rapid and reversible change in the lipid architecture of the plasma membrane of live boar sperm: the change is detectable as an increase in the cells' ability

Reliable protocols were established for investigating asymmetric distributions of 6-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino-caproyl (C6NBD) phospholipids in the plasma membrane of boar sperm cells under physiological conditions. A method based on fl

In this investigation we sought to determine whether sperm capacitation in vitro is accompanied by changes in the functional presence of zona binding sites on the plasma membrane of boar spermatozoa. During sperm incubation at 39°C in various modifi

For many years, andrologists have sought ways of assessing sperm fertility, especially of new sires entering the breeding chain. As knowledge of the complex processes that enable sperm to fertilize eggs has increased, it has become clearer that quant

Bicarbonate/CO2 is believed to be the key in vitro effector of sperm capacitation, a process which induces major changes in the sperm plasma membrane in preparation for fertilization. In a flow cytometric study, we examined the effect of bicarbonate
