ABSTRACT While lipophilic antioxidants such as flavonols may improve the preservation capacity of sperm at 17°C, their low stability and bioavailability can reduce their biological effectiveness. Encapsulation strategies have been proposed to improve the delivery and cellular availability of hydrophobic antioxidants.

A fast transient hyperpolarization occurs during the sea urchin sperm acrosome reaction induced by egg jelly [PDF]
The egg jelly-induced sea urchin sperm depolarization, assayed with the membrane potential-sensitive dye diS-C3-(5), is preceded by a fast quenching, which was initially taken as an artifact.

Effect of Uncoated Magnetic Nanoparticles on Stallion Sperm Parameters: Influence of Semen Quality
ABSTRACT The aim of this study was to evaluate the effect of uncoated, non‐functionalised magnetic nanoparticles (MNPs) on stallion sperm and to determine whether these effects depend on initial semen quality. Ten cooled ejaculates from 3 stallions were exposed to different MNP concentrations ([MNPs] = 0, 5, 25, and 50 mg/mL), agitated, and exposed to ...

Sperm Recovery and Evaluation in Domestic Species: Challenges and Current Practices
ABSTRACT Semen collection is a key step in the development of assisted reproductive technologies (ARTs) in domestic mammals, as the collection method determines the functionality and fertility of the sperm. The artificial vagina or manual collection yields ejaculates similar to those obtained during natural mating, although they require prior training ...

Capacitation and acrosome reaction in stallion spermatozoa : functional and clinical aspects [PDF]
Male fertility requires completion of a sequence of elaborate processes including not only spermatogenesis, sperm transport, accessory gland secretion and sperm deposition in the female reproductive tract, but also two very important sperm related events,

Acrosome reaction studies after induction with calcium ionophore, A23187.
Induction of acrosome reaction was seen in MT- spermatozoa with 0.2 µM A23187, when evaluated at 3, 4 and 5 h of capacitation.
