Fertility Sterility DiscussionEffect 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, 2016
Lower 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

Reflections on "Spermatozoa from patients with seminal alterations exhibit a differential miRNA profile" by Salas-Huetos et al.Concordance among sperm deoxyribonucleic acid integrity assays and semen parameters
Monday, June 29, 2015
The 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, 2014
Men 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.Semen analysis parameters Stay calm they are just numbers

Reflections on "The impact of sperm morphology on the likelihood of pregnancy following intrauterine insemination" by Deveneau et al.Male infertility testing Reactive oxygen species and antioxidant capacity
Tuesday, November 25, 2014
Elevated reactive oxygen species (ROS) levels have been associated with abnormal semen parameters and male infertility. The impact ofROSon fertilization rates and pregnancy remains controversial.Beyond bulk semen parameters

What 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.Youth varicocele and varicocele treatment A meta analysis of semen outcomes
Wednesday, July 30, 2014
A 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.Acrosome reaction is impaired in spermatozoa of obese males A preliminary study
Tuesday, July 22, 2014
Sperm acrosome reaction is impaired in obese men, showing a reduced response to P and an elevated spontaneous component, which may affect sperm fertilization potential.Semen quality of consecutive ejaculates from cancer patients for fertility preservation
Monday, June 30, 2014
This is the first study showing that repeated ejaculates from cancer patients did not show substantial variation in semen quality.Sperm proteomics Fertility diagnostic testing beyond the semen analysis

Friday, June 28, 2013
In subfertile women with anovulation we evaluated the prevalence of additional fertility-reducing factors and the diagnostic and prognostic capacity of fertility tests.
Proteomic analysis of seminal plasma in adolescents with and without varicocele
Wednesday, January 2, 2013
Normal 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.Determination of Male Infertility Is the 2010 WHO Reference Range Helpful or Confusing

Reflections 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, 2012
Fifteen 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.
