Nanoliposome‐Mediated Delivery of Lipophilic Antioxidants as a Strategy to Improve the Preservation Capacity of Pig Semen at 17°C

open access: yesReproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
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.

Effects of the purified IGF-I complex on the capacitation and acrosome reaction of rabbit spermatozoa

open access: yes, 2001
A protein complex containing IGF-I, purified from rabbit seminal plasma, was used to investigate its effects on the capacitation and acrosome reaction of rabbit spermatozoa.

A fast transient hyperpolarization occurs during the sea urchin sperm acrosome reaction induced by egg jelly [PDF]

open access: yes, 1987
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

open access: yesReproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
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 ...

Effects of native human zona pellucida glycoproteins 3 and 4 on acrosome reaction and zona pellucida binding of human spermatozoa

open access: yes, 2008
Acrosome reaction is crucial to the penetration of spermatozoa through the zona pellucida (ZP). Glycosylation of ZP glycoproteins is important in spermatozoa-ZP interaction.

Effect of acrosome reaction progress in frozen-thawed boar spermatozoa on the efficiency of in vitro oocyte fertilization

open access: yesVeterinární Medicína, 2010
A good functional status of cryopreserved boar spermatozoa is very important for successful fertilization of porcine oocytes and in vitro embryo production.

Sperm Recovery and Evaluation in Domestic Species: Challenges and Current Practices

open access: yesReproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
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 ...

Acrosome reaction studies after induction with calcium ionophore, A23187.

open access: yes, 2014
Induction of acrosome reaction was seen in MT- spermatozoa with 0.2 µM A23187, when evaluated at 3, 4 and 5 h of capacitation.
