Functional significance of responsiveness to capacitating conditions in boar spermatozoa.
TLDR
The combination of sperm responsiveness parameters applied here is a suitable tool for the evaluation of sperm function and improved the prediction level of multiple regression models for farrowing rate and litter size.About:

Journal ArticleDOI
Zinc alpha 2-glycoprotein: a multidisciplinary protein.
TL;DR: The discussion of the major aspects of ZAG from its gene structure to function and metabolism is discussed, which suggests that ZAG may have a role in the expression of the immune response.
Journal ArticleDOI
In vitro evaluation of sperm quality.
E. Mocé,James K. Graham +1 more
TL;DR: Current and past data, correlating laboratory assay data with sperm fertility are presented in an effort to determine which types of assays are important to conduct and when to conduct them.
Journal ArticleDOI
Identifying non-sperm particles during flow cytometric physiological assessment a simple approach
TL;DR: This work has developed a simple and cost-efficient flow cytometric approach for identifying non-sperm particles that can be carried out in parallel with functional assessments and is suitable for obtaining accurate sperm counts during routine semen evaluation.
Journal ArticleDOI
Freezability prediction of boar ejaculates assessed by functional sperm parameters and sperm proteins.
TL;DR: Assessing both the conventional sperm quality parameters and the immunolabeling of three proteins involved in the physiology of the sperm cell suggest that analyzing these sperm kinematic parameters could be a useful tool for predicting the potential freezability of an ejaculate.
Journal ArticleDOI
Identifying useable semen
TL;DR: Improved techniques for evaluating semen characteristics directly related to the fertilization process, such as IVM-IVF assays, analysis of seminal plasma protein markers, and discriminatory tests of sperm motility and morphology are reviewed with the goal of identifying high-index boars whose fertility is sustained when low numbers of sperm are used for AI.

Membrane contact with oviductal epithelium modulates the intracellular calcium concentration of equine spermatozoa in vitro.
TL;DR: Results indicated that membrane contact between equine spermatozoa and OEC is required to maintain low [Ca2+]i, delay capacitation, and prolong viability of spermatozosa in vitro.
Journal ArticleDOI
Selective sperm binding to pig oviductal epithelium in vitro.
TL;DR: Individual differences revealed by this study and their relation to morphology and contact of spermatozoa with seminal fluid indicate a selective function of sperm-oviduct binding.

Acrosome-intact boar spermatozoa initiate binding to the homologous zona pellucida in vitro.
Alireza Fazeli,Willem J. Hage,Feng-Pang Cheng,W. F. Voorhout,A. Marks,M.M. Bevers,Ben Colenbrander +6 more
TL;DR: Observations indicate that acrosome-intact boar spermatozoa initiate binding to the pig zona pellucida by studying the acrosomal status of sperm bound to zonaepellucidae.
Journal ArticleDOI
Capacitation of mammalian spermatozoa in vivo, with a specific focus on events in the Fallopian tubes.
TL;DR: It is argued strongly that for those sperm cells involved in fertilisation, the process of capacitation represents an active and specific coordination within succeeding regions of the female tract and one whose completion is synchronised with the events of ovulation.

Bicarbonate Stimulation of Boar Sperm Motility via a Protein Kinase A—Dependent Pathway: Between-Cell and Between-Ejaculate Differences Are Not Due to Deficiencies in Protein Kinase A Activation
TL;DR: It is concluded that intersperm and interejaculate differences in boar sperm motility are not due to inadequacy in cAMP supply or to ineffective PKA activity.
