Motile sperm organelle morphology examination (MSOME): intervariation study of normal sperm and sperm with large nuclear vacuoles

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...

The 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...

Efficacy of the motile sperm organelle morphology examination (MSOME) in predicting pregnancy after intrauterine insemination

BACKGROUND Although the motile sperm organelle morphology examination (MSOME) was developed merely as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in the evaluation of semen quality. The aim of this study was to determine the prognostic value of normal sperm morphology using MSOME with regard to clinical pregnancy (CP) after in...

Motile sperm organelle morphology examination is stricter than Tygerberg criteria.

The present study aimed to evaluate the correlation between the motile sperm organelle morphology examination (MSOME) and a well-known sperm morphology classification (Tygerberg criteria). For MSOME, spermatozoa were analysed at x8400 magnification by inverted microscope equipped with Nomarski differential interference contrast optics, Uplan Apo x100 oil/1.35 objective lens and variable zoom le...

The Influence of Sperm Morphology, Total Motile Sperm Count of Semen and the Number of Motile Sperm Inseminated in Sperm Samples on the Success of Intrauterine Insemination
