Introduction: The objective of this study was to analyze longitudinal changes in sperm parameters of Bangladeshi men. We hypothesized that semen parameters declined for this population. Methods: We retrospectively analyzed semen data from men aged 18-64 years who sought care for general sperm quality or updates on fertility status at an infertility clinic in Dhaka, Bangladesh, from January 2000 to June 2016 (n = 13,953). Samples with incomplete data were excluded (n = 143)...

In this study we aimed to evaluate the effect on reproductive outcome of HPV vaccination in male subjects of infertile couples with HPV semen infection. In this single-center study, we retrospectively enrolled 151 infertile couples with detection of HPV in semen, attending our Hospital Unit of Andrology between January 2013 and June 2015, counseled to receive adjuvant HPV vaccination. Seventy-nine accepted vaccination (vaccine group) whilst 72 did not (control group). Our protocol of follow-up, aimed to evaluate HPV viral clearance, consisted in semen analysis, INNO-LiPA and FISH for HPV in semen cells after 6 and 12 months from basal evaluation...

This study aims to evaluate the predictive value of left testicular volume (LTV) and right testicular volume (RTV) for testicular function respectively. Men who requested fertility testing for any reason were enrolled from December 2012 to November 2015. Subjects with primary scrotal diseases or a condition interfering reproductive system were excluded. Testicular volume (TV) was evaluated by scrotal ultrasound. Sex hormone and semen analysis including sperm concentration (SC) and sperm motility rate (SMR) were performed...

PURPOSE: Variations in sperm telomere length (STL) have been associated with altered sperm parameters, poor embryo quality, and lower pregnancy rates, but for normozoospermic men, STL relevance in IVF/ICSI is still uncertain. Moreover, in all studies reported so far, each man's STL was linked to the corresponding female partner characteristics. Here, we study STL in sperm donor samples, each used for up to 12 women, in order to isolate and determine the relationship between STL and reproductive outcomes...

Physical properties of crystalline materials often manifest themselves as atomic displacements either away from symmetry positions or driven by external fields. Especially the origin of multiferroic or magnetoelectric effects may be hard to ascertain as the related displacements can reach the detection limit. Here we present a resonant X-ray crystal structure analysis technique that shows enhanced sensitivity to minute atomic displacements. It is applied to a recently found crystalline modification of strontium titanate that forms in single crystals under electric field due to oxygen vacancy migration...

BACKGROUND: Reduced fertility is a common potential problem among males with congenital adrenal hyperplasia (CAH), with nearly half experiencing impaired sperm production. The major cause of oligo/azoospermia in CAH is testicular adrenal rest tumors (TARTs). Studies indicate that ultrasound screening for TARTs should begin during childhood, yet it remains unclear whether boys with CAH are routinely screened for TARTs and/or counseled about infertility risk and potential interventions such as fertility testing and/or preservation...

Studies have shown that the effects of ambient particulate matter (PM) may be related to particle's size. However, results on the relationships between different PM and reproductive health are controversial. To explore the impacts of various PM fractions on male reproductive health, a total of 796 eligible subjects recruited in 2013 baseline investigation. In addition, there were 656 (82.4%) and 568 (71.3%) subjects participated follow-up surveys in 2014 and 2015, respectively. We used multivariable regression analysis and mixed-effect model to investigate the associations between air pollutants PM10, PM10-2...

BACKGROUND: The timing of the first cell divisions may predict the developmental potential of an embryo, including its ability to establish pregnancy. Besides differences related to metabolism, stress, and survival, embryos with different speeds of development present distinct patterns of gene expression, mainly related to energy and lipid metabolism. As gene expression is regulated by epigenetic factors, and that includes DNA methylation patterns, in this study we compared the global DNA methylation profile of embryos with different kinetics of development in order to identify general pathways and regions that are most influenced by this phenotype...

Associations between male infertility and cancer are gaining clinical attention. Relationships between infertility and cancer have traditionally been studied in women, but recent work has focused on the male component of reproduction. Infertile men are at an elevated risk to develop various malignancies later in life, primarily genitourinary malignancies such as testicular and prostate cancer. Rates of testicular and high-grade prostate cancer in infertile men appear to be at least double the risk in the general population...

Zambia has recently reported high incidences of sexual abuse against women and children. Zambian law categorises sexual offences into rape, defilement, incest and others, with defilement constituting the majority of the reported cases (>89%). Between 2010 and 2012, convictions of defilement cases were achieved in only 13% of cases reported to the police. DNA evidence has shown prominence in resolving crimes, specifically as an identification tool in sexual offences. Currently there is no empirical evidence describing the role of forensic evidence in sexual crimes in Zambia; as such a retrospective study was conducted to evaluate this between 2007 and 2014 (n = 1154)...

In this paper, we describe the development of a novel method to detect oral bacteria by combining direct polymerase chain reaction (direct PCR) with an immunochromatographic strip (ICS), enabling the identification of saliva in forensic samples. Direct PCR was first used to directly amplify specific oral bacterial sequences (from Streptococcus sanguinis and Streptococcus salivarius) from swab samples, circumventing the need for tedious sample preparation steps such as cell lysis and DNA extraction and purification...
