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

Reproduction 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 ...

Modulation of spermatozoon acrosome reaction

, 2011
Spermatozoon acrosome reaction is an exocytotic event of the utmost importance for the development of mammalian fertilisation. Current evidence shows that the triggering of the acrosome reaction (AR) could be regulated by the action of diverse compounds,

Genistein\u27s Effect on Acrosome Reaction of Ram Sperm

, 2011
Capacitation and acrosome reaction are important processes that sperm cells must undergo in the female reproductive tract in order for fertilization of the ova to occur. Genistein, a phytoestrogen, has been shown to inhibit protein tyrosine kinase (PTK)

Improved methodology for the detection and quantification of the acrosome reaction in mouse spermatozoa. [PDF]

, 2009
This study evaluates the use of two fluorescein-labelled (FITC) plant lectins, Pisum sativum (edible pea) agglutinin (PSA) and Arachis hypogaea (peanut) agglutinin (PNA), in order to determine the most accurate and reliable method to experimentally ...

Protease activity involvement in the passage of mammalian sperm through the zona pellucida

Biological Research, 2011
The interaction between acrosome-reacted sperm and zona pellucida proteins is not yet fully understood. Serine protease acrosin and its zymogen proacrosin have been proposed to fulfill this function due to their capacity to bind zona pellucida ...

Dynamics of PLCζ During Acrosome Reaction in Frozen Ram Spermatozoa

Despite advancements in assisted reproductive techniques, intracytoplasmic sperm injection (ICSI) success remains limited in ruminants, notably in sheep, suggesting underlying factors negatively affecting early embryonic development [1].
