Motile sperm organelle morphology examination (MSOME): intervariation study of normal sperm and sperm with large nuclear vacuoles
BACKGROUND Although the motile sperm organelle morphology examination (MSOME) was developed only as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in evaluation of semen quality, with potential clinical repercussions. The present study aimed to evaluate individual variations in the motile sperm organelle morphology examination (M...
متن کاملRe: sperm vacuoles are linked to capacitation and acrosomal status.
STUDY QUESTION Is the presence of nuclear vacuoles really a negative parameter? SUMMARY ANSWER As sperm vacuoles are associated with acrosomal and capacitation status, they appear to be a reflection of normal sperm physiology. WHAT IS KNOWN ALREADY The selection of sperm under a high magnification has been proposed as a strategy to increase the success rates of ICSI, through a better select...
متن کاملThe effects of male age on sperm analysis by motile sperm organelle morphology examination (MSOME)
BACKGROUND This study aimed to investigate the influence of age on sperm quality, as analysed by motile sperm organelle morphology examination (MSOME). METHODS Semen samples were collected from 975 men undergoing evaluation or treatment for infertility. Sperm cells were evaluated at 8400× magnification using an inverted microscope equipped with Nomarski (differential interference contrast) op...
متن کاملAcrosomal Disruption in Sperm
"Capacitation" is a physiological event which alters sperm to permit rapid penetration through oocyte investments and fusion between gametes. Acrosomal "reaction," the physiological release of acrosomal contents, occurs after this facilitating process. In this study, acrosomal "disruption" of guinea pig and rat sperm was achieved in vitro by incubating sperm together with the follicular content...
متن کاملAcrosomal Reaction of Thyone Sperm
Structural changes inside the head of Thyone sperm undergoing the acrosomal reaction were followed with a high-resolution, differential interference contrast (DIC) video microscope . The beating sperm, adhering by their midpiece to the cover slip of a wedge perfusion chamber, were activated by a calcium ionophore (201uM A23187) suspended in sea water containing 50 mM excess CaC12. Before activa...
