The effects of male age on sperm analysis by motile sperm organelle morphology examination (MSOME)
(Biomed Central Ltd., 2012-03-19)
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 ...
Effect of leukocytospermia and processing by discontinuous density gradient on sperm nuclear DNA fragmentation and mitochondrial activity
(Springer, 2009-03-01)
To assess the effect of leukocytospermia and semen processing on sperm DNA and mitochondria.Twenty-two patients with and 41 without leukocytospermia were included. Sperm DNA fragmentation was assessed by the Comet assay, ...
DNA fragmentation of normal spermatozoa negatively impacts embryo quality and intracytoplasmic sperm injection outcome
(Elsevier Science Inc, 2010-07)
Objective: To evaluate DNA fragmentation in morphologically normal sperm recovered from the same sample used for intracytoplasmic sperm injection (ICSI) and to correlate DNA damage with embryo quality and pregnancy outcome. ...
Sperm nuclear DNA fragmentation in adolescents with varicocele
(Elsevier B.V., 2006-03-01)
Objective: To verify if sperm from adolescents with varicocele have an increased rate of DNA fragmentation when compared with adolescents without varicocele.Design: Controlled prospective study.Setting: Patients in an ...
Does sperm quality and DNA integrity differ in cryopreserved semen samples from young, adult, and aged Nellore bulls?
(2017-06-21)
Background: In humans, it is now well documented that rising paternal age is correlated with decreased sperm DNA integrity and embryonic developmental failures. On the other side of the coin, it is also reported that very ...
Large nuclear vacuoles are indicative of abnormal chromatin packaging in human spermatozoa
(Wiley-Blackwell, 2012-02-01)
The aim of this investigation was to determine the presence of abnormal sperm chromatin packaging in spermatozoa with large nuclear vacuoles (LNV) selected via high magnification by analysing the pattern of chromomycin A3 ...

Melatonin Protective Role in Mouse Cauda Epipidymal Spermatozoa Damage Induced by Sodium Arsenite
(Soc Chilena Anatomia, 2013-12-01)
We evaluated the sperm parameters such as cauda epididymis weight, sperm count, sperm morphology and sperm DNA stability of adult CF-1 male mice treated daily (oral exposure) with the toxic sodium arsenite (As, 7.0 mg/kg/body ...
Correlation between semen analysis by motile sperm organelle morphology examination and sperm DNA damage
(Elsevier B.V., 2010-10-01)
Regression analysis of 538 semen samples demonstrated that percentages of normal nuclear sperm and all spermatozoa with abnormalities of nuclear form at high magnification had significant negative correlation with percentages ...
