This study evaluated the effects of cooling, freezing and thawing on the plasma membrane integrity, kinetics and expression of two sugar transporters glucose transporter-3 and -5 (GLUT-3 and GLUT-5) in spermatozoa from Iberian boars. Semen samples were collected twice weekly from eight young, fertile Iberian boars of the ‘Entrepelado’ and ‘Lampiño’ breeds. The samples were suspended in a ...... hiện toàn bộ
Induced hyperactivity in boar spermatozoa and its evaluation by computer-assisted sperm analysisReproduction - Tập 128 Số 2 - Trang 171-179 - 2004
Harald Schmidt, Günter Kamp
Hyperactivity, a form of sperm motility characterized by vigorous flagellar movements, has been proposed as essential for fertilization in mammals. The objective of the present study was to establish a method for inducing hyperactivityin vitroin boar spermatozoa and to define threshold values to differentiate between hyperactive and non-hyperactive spermatozoa by...... hiện toàn bộ

In this study, we investigated whether neonatal exposure to a glyphosate-based herbicide (GBH) alters the reproductive performance and the molecular mechanisms involved in the decidualization process in adult rats. Newborn female rats received vehicle or 2 mg/kg/day of a GBH on postnatal days (PND) 1, 3, 5 and 7. On PND90, the rats were mated to evaluate (i) the reproductive performance on...... hiện toàn bộ
