Epididymis cholesterol homeostasis and sperm fertilizing ability.
Cholesterol, being the starting point of steroid hormone synthesis, is a long known modulator of both female and male reproductive physiology especially at the level of the gonads and the impact cholesterol has on gametogenesis. Less is known about the effects cholesterol homeostasis may have on postgonadic reproductive functions. Lately, several data have been reported showing how imbalanced c...
متن کاملAutomation of human sperm cell analysis by flow cytometry.
Semen sample analysis is routinely performed by microscopical evaluation and manual techniques by laboratory operators; the analysis is affected by a wide imprecision related to variability among observers, influencing its clinical validity. Our aim was to automate sperm analysis with the use of flow cytometry for evaluation of cell counts and typing and with the use of a new membrane-permeant ...
متن کاملStudy of mitochondrial membrane potential, reactive oxygen species, DNA fragmentation and cell viability by flow cytometry in human sperm.
BACKGROUND Sperm cell death appears to be a cause of male infertility. The objective of this study was to determine the most reliable method for the evaluation of sperm quality in semen samples during sperm preparation for IVF. METHODS Conventional analysis of semen samples was compared with several cytofluorometric methods detecting death-associated changes. Neat semen from infertile patient...
متن کاملRANTES and human sperm fertilizing ability: effect on acrosome reaction and sperm/oocyte fusion.
Beta-chemokine, regulated on activation and normally T-cell expressed and presumably secreted (RANTES), is present in both the male and female genital tract fluids where its levels increase in diseases related to infertility, such as endometriosis and male genital tract infections. beta-Chemokine receptors (CCR3 and CCR5) are expressed on freshly ejaculated human sperm cells and a sperm chemoat...
متن کاملComparison of Motility, Morphology, Acrosome Integrity, Membrane Integrity and Fertilizing Ability of Frozen-Thawed Buffalo Sperm Separated by a Percoll
The aim of this study was to evaluate sperm quality following separation and selection using a silane-coated silica colloid method (PureSperm ® ) or Percoll ® . Frozen/thawed sperm from buffalo bulls (n=5) were assigned to two groups. The first group was separated using a Percoll ® discontinuous gradient (45 and 90%) and the second group by a single layer of PureSperm ® . Sperm motility, concen...
