BACKGROUND: Sperm DNA fragmentation measured by different techniques make comparisons impossible due to lack of standardization. Induction of DNA damage after sperm preparation in the entire fraction has been observed on independent occasions but findings are not consistent. METHODS: Men presenting at a University hospital setup for infertility treatment. DNA damage via TUNEL assay was validated on fresh semen samples, as conventional semen parameters, to reduce variability of results...

PurposeNonobstructive azoospermia (NOA) affects 1% of the male population; however, despite state-of-the-art clinical assessment, for most patients the cause is unknown. We capitalized on an analysis of multiplex families in the Middle East to identify highly penetrant genetic causes.MethodsWe used whole-exome sequencing (WES) in 8 consanguineous families and combined newly discovered genes with previously reported ones to create a NOA gene panel, which was used to identify additional variants in 75 unrelated idiopathic NOA subjects and 74 fertile controls...

The most common human sex chromosomal disorder is Klinefelter syndrome (KS; 47,XXY). Adult patients with KS display a diverse phenotype but are nearly always infertile, due to testicular degeneration at puberty. To identify mechanisms causing the selective destruction of the seminiferous epithelium, we performed RNA-sequencing of 24 fixed paraffin-embedded testicular tissue samples. Analysis of informative transcriptomes revealed 235 differentially expressed transcripts (DETs) in the adult KS testis showing enrichment of long non-coding RNAs, but surprisingly not of X-chromosomal transcripts...

BACKGROUND: Male factor infertility is quite common as 30-50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility. Many factors cause sperm DNA fragmentation and could be testicular or post-testicular. The purpose of this study was to assess relationships among sperm DNA fragmentation, lifestyle factors and semen values of Saudi men and to determine impact of sperm DNA fragmentation on ICSI cycle outcome. METHODS: The duration of this study was from January 2015 to June 2016...

PURPOSE OF REVIEW: Current guidelines recommend against surgical repair of subclinical varicoceles (SCVs) for infertility; several studies demonstrate mixed fertility results after SCV correction. To determine whether surgical correction of SCV improves semen parameters and/or reproductive outcomes, we performed a systematic review and meta-analysis. Seven biomedical literature databases were searched through January 2018 for studies that assessed reproductive outcomes and/or change in semen parameters in men with corrected SCV compared to either (1) uncorrected SCV or (2) corrected clinical varicocele...

PURPOSE OF REVIEW: In many countries, the average age of paternity is rising. The negative effect of older age on fertility in women is well documented; however, less is known about the impact of paternal age on fecundity. In this review, we summarize the current knowledge of how paternal age affects semen parameters, reproductive success, and offspring health. RECENT FINDINGS: Contemporary evidence confirms that aged men have worse semen parameters, including overall negative changes in sperm genetics...

This article examines how the British press represented Patrick Steptoe and Robert Edwards in the story of the birth of the first 'test-tube baby', Louise Brown. In 1978, the British press represented the birth of Louise Brown as both a success and a source of hope. The main pairs of protagonists in this story were Steptoe and Edwards and Lesley and John Brown, who metonymically represented British science and infertile couples, respectively. In the dominant 'success' narrative of the birth of Louise Brown as depicted in the British press in 1978, Edwards and Steptoe seemed to embody 'British' values of industriousness, perseverance, altruism, ingenuity and teamwork...

The male factor contributes to 50% of infertility. The cause of male infertility is idiopathic and could be congenital or acquired. Among different factors which are involved in idiopathic male infertility, genetic factors are the most prevalent causes of the disease. Considering, the high prevalence of male infertility in Iran and the importance of genetic factors in the accession of it, in this article we reviewed the various studies which have been published during the last 17 yr on the genetic basis of male infertility in Iran...

REVIEW

Ageing is usually characterised by a mild chronic proinflammatory state. Despite the tight association between both processes, the phenomenon has recently been termed inflammageing. Inflammation in the male reproductive tract is frequently linked with bacterial or virus infections but also with a broad range of noninfectious processes. Prostatitis, epididymitis and orchitis, among others, can lead to infertility. However, in spite of the inflammation theory of disease, chronic inflammation in male urogenital system does not always cause symptoms...

Only few studies have focused on organochlorine pesticides (OCPs) in breast milk and the related health risks for women in Taiwan. Our goal is to examine breast milk OCPs and their associations with female reproductive function (infertility, gynecological diseases, and menstruation characteristics) as well as their correlation with sociodemographic parameters (age, pre-pregnant body mass index (BMI), annual incomes, population, birth year, and parity) and dietary habit. The breast milk samples were collected in southern Taiwan ( n = 68) from 2013 to 2016 and the OCP residues were analyzed using high resolution gas chromatography with low resolution mass spectrometry (HRGC/LRMS)...
