Dietary Patterns and Their Relationship With Semen Quality( )

in English and held by 1 WorldCat member library worldwide

Diet is a complex exposure variable, which calls for multiple approaches to examine the relationship between diet and disease risk. To address these issues, several authors have recently proposed studying overall dietary patterns by considering how foods and nutrients are consumed in combinations. The aim of the study was to investigate the associations between dietary patterns, semen quality parameters, and the level of reproductive hormones. The study population consisted of 336 men who attended the infertility clinic for diagnostic purposes and who had normal semen concentration of 20 to 300 mln/ml or slight oligozoospermia (semen concentration of 15-20 mln/ml). Participants were interviewed, and a semen sample was provided by them. Diet was assessed via food frequency questionnaire, and dietary patterns were identified by factor analysis. Men were classified into three groups according to scores of each dietary pattern: Western, Mixed, or Prudent. A positive association was observed between sperm concentration and Prudent dietary pattern, and level of testosterone and Prudent dietary pattern (p = .05, p = .03, respectively). Additionally, Prudent dietary pattern was identified to decrease the DNA fragmentation index (p = .05). The results were adjusted for sexual abstinence, age, smoking, past diseases, and alcohol consumption. Higher consumption of a Prudent dietary pattern was associated with higher sperm concentration and higher level of testosterone. Sperm chromatin structure was inversely related to higher consumption of a Prudent dietary pattern. Further research is needed to confirm these findings and extend these results to other populations

The effect of environmental exposure to pyrethroids and DNA damage in human sperm( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract: The present study was designed to investigate whether environmental exposure to pyrethroids was associated with sperm DNA damage. Between January 2008 and April 2011 286 men under 45 years of age with a normal sperm concentration of 15-300 10 6 /ml [WHO 2010] were recruited from an infertility clinic in Lodz, Poland. Participants were interviewed and provided urine, saliva, and semen samples. The pyrethroids metabolites: 3-phenoxybenzoic acid (3PBA), cis -3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropane carboxylic acid (CDCCA), trans -3-(2, 2-dichlorovinyl)-2, 2-dimethylcyclopropane carboxylic acid (TDCCA), and cis -2, 2-dibromovinyl-2, 2-dimethylcyclopropane-carboxylic acid (DBCA) were analyzed in the urine using a validated gas chromatography ion-tap mass spectrometry method. Sperm DNA damage was assessed using a flow cytometry based on sperm chromatin structure assay (SCSA). A positive association was observed between CDCCA>50th percentile and the percentage of medium DNA fragmentation index (M DFI) and percentage of immature sperms (HDS) (p = 0.04, p = 0.04 respectively). The level of 3PBA>50th percentile in urine was positively related to the percentage of high DNA fragmentation index (H DFI) (p = 0.03). The TDCCA, DBCA levels, and the sum of pyrethroid metabolites were not associated with any sperm DNA damage measures. Our results suggest that environmental pyrethroid exposure may affect sperm DNA damage measures index indicated the reproductive effects of pyrethroid exposure on adult men. In view of the importance of human reproductive health and the widespread usage of pyrethroids, it is important to further investigate these correlations
An observational study of assisted reproductive technology outcomes in new European Union member states: an overview of protocols used for ovarian stimulation( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

Background: The development of new fertility treatment options has facilitated individualized assisted reproductive technology (ART) protocols to improve outcomes. Manufacturing improvements to recombinant human follitropin alfa have allowed precise dosing based on mass (filled-by-mass; FbM) rather than bioactivity (filled-by-bioassay; FbIU). Continued monitoring and reporting of follitropin alfa treatment outcomes in routine clinical practice is essential. Objective: To provide an overview of the frequency of different controlled ovarian-stimulation protocols used in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles in new European Union member states, and to provide post-registration efficacy and safety data on follitropin alfa. Research design and methods: A 2-year, prospective, observational, multicentre, Phase IV study conducted at ART clinics in the Czech Republic, Estonia, Latvia, Lithuania, Poland, Slovakia and Slovenia. Women aged 18-47 years undergoing ovarian stimulation with follitropin alfa for conventional IVF or ICSI were eligible for inclusion. The main treatment outcome was cumulative clinical pregnancy rate. Data were analysed descriptively. RESULTS: Clinical pregnancy outcomes were available for 4055 of 4085 (99.3%) patients. In total, 1897 (46.8%) patients used follitropin alfa FbIU; 2133 (52.6%) used follitropin alfa FbM. Clinical pregnancy was achieved by 39.5% (1603/4055) of patients. A greater proportion of patients with polycystic ovary syndrome achieved a clinical pregnancy than those with endometriosis (41.8% vs 37.8%, respectively). A higher cumulative pregnancy rate was observed with the use of follitropin alfa FbM than follitropin alfa FbIU (41.3% vs 37.8%, respectively; p = 0.02). Conclusions: This study represents the most comprehensive audit of individualized ART in clinical practice in Central and Eastern Europe. Overall, clinical pregnancy was achieved by 39.5% of patients after stimulation with follitropin alfa. The use of follitropin alfa FbM resulted in a higher cumulative pregnancy rate than did the FbIU formulation. However, limitations of the study include the observational and non-comparative study design, and descriptive nature of statistical analyses; furthermore, the study was not designed to make direct comparisons between the success rates of different ovarian-stimulation protocols
Exposure to widespread environmental endocrine disrupting chemicals and human sperm sex ratio( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: In recent years, a trend toward a declining proportion of male births has been noted in several, but not all, industrialized countries. The underlying reason for the drop in the sex ratio is unclear, but one theory states that widespread environmental endocrine disrupting chemicals affecting the male reproductive system in a negative manner could be part of the explanation. The present study was designed to investigate whether the urinary phthalate, pyrethroids and polycyclic aromatic hydrocarbons metabolites concentrations were associated with sperm Y:X ratio. The study population consisted of 194 men aged under 45 years of age who attended infertility clinic in Lodz, Poland for diagnostic purposes with normal semen concentration of 20-300 mln/ml or with slight oligozoospermia (semen concentration of 15-20 mln/ml) (WHO, 1999). The Y:X ratio was assessed by fluorescent in situ hybridization. Urinary concentrations of 1-hydroxypyrene were measured by high performance liquid chromatography, phthalate metabolites were analyzed using a procedure based on the LC-MS/MS methods and metabolites of synthetic pyrethroids were assessed by gas chromatography ion-tap mass spectrometry method. After adjustment for potential confounders (past diseases, age, abstinence, smoking, alcohol consumption, sperm concentration, motility, morphology) 5OH MEHP, CDCCA to TDCCA and 1-OHP was negatively related to Y:X sperm chromosome ratio (p=0.033, p<0.001, p=0.047 respectively). As this is the first study to elucidate the association between the level of metabolites of widespread environmental endocrine disrupting chemicals (phthalates, synthetic pyrethroids, polycyclic aromatic hydrocarbons) on sex chromosome ratio in sperm therefore, these findings require further replication in other populations. Highlights: Urinary phthalate metabolites levels were significantly associated with a decrease in Y/X chromosome bearing sperm. The levels of 1-hydroxypyrene in urine were negatively related to Y:X sperm chromosome ratio. Our results showed that urinary level of metabolites of synthetic pyrethroids decrease the sperm sex ratio. Abstract : Exposure to endocrine disrupting chemicals and Y:X sperm chromosome ratio
