Method for determining the sperm quality of vertebrate animals
François Guillaume,Le Corvec Maena,De Bretagne Thomas,Gildas Michel,Basquin Stephane,Charreaux Frederic,Hughes Tariel,Benoît Guyonnet +7 more
TL;DR: In this article, a method for determining the sperm quality of vertebrate animals was proposed, which comprises the following steps: measuring at least one absorption spectrum of a sample of the sperm, selecting a number n of wave numbers σ j (j∈[1;n]) characteristic of sperm from the animal's breed or species; on the basis of said at least spectrum, determining a value for the absorption X j and/or a value of the second derivative of the absorption x j " (j ∈[ 1,n]) for each of said n wave numbers

TL;DR: In this paper, a method for determining the sperm quality of vertebrate animals was proposed, which comprises the following steps: Measuring at least one absorption spectrum of a sample of the sperm, selecting a number n of wave numbers sj (j?[1;n]) characteristic of sperm from the animal's breed or species; on the basis of said at least spectrum, determining a value for the absorption Xj and/or a value of the second derivative of the absorption xj" (j?[1,n]) for each of said n wave number sj
Dissertation
Optimization of a sperm-oviduct binding assay mimicking in vivo conditions. Adoption of sperm separation methods and protocols for analysing sperm motility and intracellular Ca2+ level
TL;DR: This work presents a meta-analysis of sperm motility research in the context of the female genital tract and focuses on the role of the oviduct in the formation of a sperm reservoir.

TL;DR: The gametes, fertilization and early embryogenesis the reproductive systems - the female, the male the pituitary and the hypothalmus, and the reproductive processes and their control.
Journal ArticleDOI
Use of fluorescent probes to assess membrane integrity in mammalian spermatozoa
TL;DR: The technique appeared to provide more reliable estimations of the percentage of functional cells than did motility estimations or assessments of acrosomal integrity, and demonstrated the sensitivity of the sperm plasma membrane to cold shock: virtually all cells rapidly became permeable to the stains after such stress.

Cholesterol efflux-mediated signal transduction in mammalian sperm: cholesterol release signals an increase in protein tyrosine phosphorylation during mouse sperm capacitation.
Pablo E. Visconti,XiaoPing Ning,Miguel W. Fornés,Juan G. Alvarez,Paula Stein,Stephanie A. Connors,Gregory S. Kopf +6 more
TL;DR: It is demonstrated that cholesterol release is associated with the activation of a transmembrane signal transduction pathway involving PK-A and protein tyrosine phosphorylation, leading to functional maturation of the sperm.
Journal ArticleDOI
Bicarbonate/CO2, an effector of capacitation, induces a rapid and reversible change in the lipid architecture of boar sperm plasma membranes
TL;DR: It is found that bicarbonate causes a rapid increase in the ability of live boar spermatozoa to bind merocyanine, apparently by perturbing enzymic control processes.
Journal ArticleDOI
Evaluation of in vitro capacitation of stallion spermatozoa.
TL;DR: It was found that merocyanine 540 detects capacitation-related changes much earlier than CTC does, and that flow cytometry for evaluation of capacitation and AR was a quicker and more accurate technique than fluorescence microscopy.
