Effect of semen quality on human sex ratio in in vitro fertilization and intracytoplasmic sperm injection An analysis of 27158 singleton infants born after fresh single embryo transfer
Friday, April 1, 2016Lower sperm motility was associated with significant lower sex ratio in in vitro fertilization whereas intracytoplasmic sperm injection was associated with significant lower sex ratio regardless of sperm quality.
Sperm DNA fragmentation and mitochondrial membrane potential combined are better for predicting natural conception than standard sperm parameters
Tuesday, March 1, 2016Sperm DNA fragmentation and mitochondrial membrane potential combined are superior to standard sperm parameters in predicting natural conception.

Tuesday, September 1, 2015Reflections on "Spermatozoa from patients with seminal alterations exhibit a differential miRNA profile" by Salas-Huetos et al.
Monday, June 29, 2015The sperm chromatin structure assay and TUNEL assay are moderately correlated measures of sperm DNA integrity but often yield conflicting results. The DNA fragmentation index is well correlated with semen analysis parameters, whereas TUNEL is not.
Analysis of semen parameters in male referrals Impact of reference limits stratification by fertility categories predictors of change and comparison of normal semen parameters in subfertile couples
Monday, December 29, 2014Men with “normal” semen results are vastly underrepresented in the referral population. Men with any semen parameter below the World Health Organization 2010 criteria demonstrated findings indicative of a global dysfunction in spermatogenesis.

Tuesday, November 25, 2014Reflections on "The impact of sperm morphology on the likelihood of pregnancy following intrauterine insemination" by Deveneau et al.
Tuesday, November 25, 2014Elevated reactive oxygen species (ROS) levels have been associated with abnormal semen parameters and male infertility. The impact ofROSon fertilization rates and pregnancy remains controversial.
Tuesday, November 25, 2014What can the analysis of semen reveal about the fertility potential of sperm? A series of articles reviews the current status and limitations of basic and advanced semen testing.
Wednesday, July 30, 2014A meta-analysis of the literature regarding youth varicocele and semen outcomes demonstrates an overall negative effect of varicocele on semen, and improvement of semen parameters following varicocele treatment.
Tuesday, July 22, 2014Sperm acrosome reaction is impaired in obese men, showing a reduced response to P and an elevated spontaneous component, which may affect sperm fertilization potential.
Monday, June 30, 2014This is the first study showing that repeated ejaculates from cancer patients did not show substantial variation in semen quality.
Sunday, June 1, 2014Reflections on "Acute epididymitis induces alterations in sperm protein composition" by Pilatz et al.
Friday, June 28, 2013In subfertile women with anovulation we evaluated the prevalence of additional fertility-reducing factors and the diagnostic and prognostic capacity of fertility tests.
Wednesday, January 2, 2013Normal semen analysis may not reflect important alterations in protein levels in the seminal plasma. A classic proteomics approach shows that unbalanced apoptosis may prevent normal spermatogenesis in the adolescent varicocele.
Thursday, November 29, 2012Reflections on Murray et al. "The Effect of the New 2010 World Health Organization Criteria for Semen Analyses on Male Infertility"
The Effect of the New 2010 World Health Organization Criteria for Semen Analyses on Male Infertility
Thursday, November 29, 2012Fifteen percent of men with previously abnormal semen analysis would be reclassified as normal by the 2010 WHO criteria. This may lead to less male infertility diagnosis or evaluation.
Thursday, September 27, 2012Reflections on "Supersensitive fluorescent semen analysis: validation on azoospermic and oligozoospermic samples"
Monday, July 30, 2012Voluntary participation in this external quality control program improved overall performance of semen analysis. Surprisingly, <8% of laboratories strictly adhered to WHO guidelines.
