OBJECTIVE To test a newly invented intracytoplasmic sperm injection (ICSI) sperm selection method based on sperm hyaluronic acid (HA) binding. DESIGN Comparison of chromosomal disomy and diploidy frequencies in sperm arising from semen and in HA-bound sperm. SETTING Academic andrology laboratory. PATIENT(S) Men presenting for semen analysis. INTERVENTION(S) Washed sperm fractions of 32 ...

OBJECTIVE To evaluate the effect of light-emitting diode (LED) on sperm motility in men with and without asthenospermia. MATERIAL AND METHODS Semen samples from 27 men were assessed and washed. An aliquot was taken from each sample as a control. The remaining amount was exposed to red LED for 2, 5 and 10 minutes. Sperm motility from the test and control tubes were re-checked at the end of eac...

BACKGROUND Kidney tonifying - spleen strengthening method being one of the modalities for treatment of astheno-oligozoospermia is currently commonly used in the clinical setting. To investigate the mechanism of YiShenJianPi (YSJP) Recipe, used in Traditional Chinese Medicine to benefit "the kidney" and strengthen "the spleen". MATERIALS AND METHODS Oligoasthenozoospermia, male BALB/c mice wer...

This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE) and vitamin E (Vit E) on sperm quality parameters in the methotrexate (MTX)-treated mice. Forty-eight young adult male mice (8-12 weeks) were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg(-...

Received Nov 09, 2015 Revised Mar 14, 2016 Accepted Mar 20, 2016 Transform-domain digital audio watermarking has a performance advantage over time-domain watermarking by virtue of the fact that frequency transforms offer better exploitation of the human auditory system (HAS). In this research paper an adaptive audio watermarking is proposed based on the low and high wavelet frequencies band (LF...

The objective of this study was to evaluate the importance of environmental and genetic factors affecting semen quality; sperm volume (SV), sperm concentration (SPCO), total sperm (TS), fresh sperm motility (FSM), total fresh motile sperm (TFMS), post thaw sperm motility (PTSM), total post thaw motile sperm (TPTMS), number of produced payout (NPP), number of fresh motile sperm in each milt ejac...

Introduction: tegrity is the most important component for transferring genetic information Sperm DNA fragmentation is considered a component of male infertility. Its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. In this study, we investigate the relationship between sperm parameters of motility, morphology, concentratio...

Background: It is stated that pentoxifyline can improve sperm motility and suggested to use in ART for asthenozoospermia. But, probable effect of this drug on sperm DNA in unknown. Our main goal was to evaluate the impact of pentoxifyline on sperm DNA fragmentation. Materials and Methods: Thirty eight asthenozoospermic patients were selected for this prospective study. After direct swim-up, spe...

Background: To establish importance of sperm DNA assessment in resolving the unexplained infertility problem. Materials and Methods: This article is based on the careful observation of texts and papers from 2000-2014 about the DNA damage assessment as a significant parameter of sperm function test. Results: Acidic Aniline blue, Sperm Chromatin Dispersion test(SCD), Malondialdehyde concentration...
