TL;DR: It is concluded that TPT causes impairment of the sperm activity, reducing it in individuals exposed in the adult phase.

Fisiología celular y calidad seminal durante la conservación del semen porcino refrigerado
TL;DR: - Ministerio de Ciencia e Innovacion (AGL 2010-15188): “Funcion de la proteina quinasa activada por AMP, AMPK, en the celula germinal masculina: posible aplicacion biotecnologica a the conservacion se semen porcino”.
Journal ArticleDOI
Suitability of the hemi-zona assay for the evaluation of the effect of the length of the equilibration period before cryopreservation.
TL;DR: It can be concluded that the hemi-zona assay is a suitable test to detect alterations in the fertilizing capacity of bovine sperm after modifying the length of the equilibration period before freezing and thawing.

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.
