The purpose of this study was to detect the effects of bacterial infection on human sperm nuclear protamines and DNA fragmentation. In this study, 120 semen samples were collected from unselected male partners of couples consulting for infertility in infertility and obstetrics clinic. All the samples were screened bacteriologically according to World Health Organization guidelines, and also sperm parameters and DNA fragmentation were evaluated. The concentrations of protamines P1 and P2 were quantified using acid urea acrylamide gel electrophoresis...

Seminal oxidative stress (OS) is well-known to affect male fertility status. The discrepancy in OS measurement has hindered its clinical use as a quality indicator for semen. Some tests measured single markers of oxidants or reductants, leading to lack of standardization of results. Oxidation-reduction potential (ORP) is a better representative for OS as it provides an overall measure of the activity of both oxidants and reductants. ORP assessment by MiOXSYS has been introduced as a measure of OS with high specificity in differentiating fertile from infertile semen samples...

Male infertility can be diagnosed by evaluation of the (female and) male history with respect to risk factors, and includes scrotal sonography, hormone and semen measurements. In severe male factor infertility, genetic testing is indicated. Treatment options vary between preventive, medical or surgical strategies depending on the underlying diagnosis. Assisted reproductive techniques may be applied as a consequence of the couple's infertility profile.

REVIEW
Ryan C Owen, Benjamin J McCormick, Bradley D Figler, Robert M Coward
A dilation of the pampiniform venous plexus in the scrotum above the testicle, called a varicocele, affects approximately 15% of the general male population. While the majority is asymptomatic, pain results in up to 10% of cases of varicoceles. The pain associated with varicoceles is typically mild and is described as heavy, achy, or dull-and is usually isolated to the testicle or spermatic cord. Guidelines clearly recommend varicocele repair in males with varicoceles, infertility, and an abnormal semen analysis...

OBJECTIVE: The aim of the current study was to evaluate the effect of an oral pretreatment with a mix of myo-inositol (Myo-Ins), folic acid, vitamin E, L-carnitine, L-arginine and selenium (Folandrol, Exeltis, Hungary) and subsequent direct Myo-Ins incubation of spermatozoa before Physiological Intra-Cytoplasmic Sperm Injection (PICSI) procedures in infertile couples due to oligoasthenoteratozoospermia with previous failed PICSI procedures. PATIENTS AND METHODS: We performed a prospective, randomized controlled trial at the Assisted Reproduction Unit of the Kaáli Institute (Győr, Hungary)...

Infertility is a worldwide problem and male partner contributes to almost 30% of cases of infertility. The term oligoasthenoteratospermia is related to defective spermatogenesis and is characterized by a reduction of motility and number of spermatozoa and a change in their morphology. Electron microscopes are frequently used in order to evaluate sperm pathology and overall to establish a correlation between structural and functional deficiencies of altered sperm. High levels of reactive oxygen species endanger sperm function and viability...

Typha capensis (Rohrb.)N.E.Br. (bulrush) is used by traditional healers in Southern Africa to treat male reproductive problems. This study aimed at investigating the effects of T. capensis on TM3-Leydig cells. T. capensis rhizome crude extract obtained from autumn, winter, spring and summer harvest was fractionated using HPLC into four fractions, and TM3-Leydig cells were incubated with different concentrations of the F1 fraction (0.01, 0.02, 0.1, 1, 10 and 100 μg/ml) for 24, 48 and 96 hr respectively...

Spermatogenesis, a highly coordinated process, is prone to environmental insults which may lead to impaired spermatogenesis or, at worst, infertility. Bisphenol A (BPA) is a well-known global environmental toxicant and a ubiquitous oestrogenic chemical. This study evaluated the role of selenium (0.5 ppm sodium selenite/kg diet) on spermatogenesis after BPA treatment in different groups of male BALB/c mice: control, selenium, BPA and selenium+BPA. Markers of oxidative stress and apoptosis were evaluated in testis after BPA treatment...

Considering the widespread use of assisted reproductive techniques (ART), DNA methylation of specific genes involved in spermatogenesis achieves increasingly clinical relevance, representing a possible explanation of increased incidence of syndromes related to genomic imprinting in medically assisted pregnancies. Several trials suggested a relationship between male sub-fertility and sperm DNA methylation, although its weight on seminal parameters alteration is still a matter of debate. To evaluate whether aberrant sperm DNA methylation of imprinted genes is associated with impaired sperm parameters...

INTRODUCTION: Idiopathic oligoasthenoteratozoospermia (iOAT) is commonly encountered during the evaluation of men with infertility. Antioxidants have been utilized empirically in the treatment of iOAT based on their ability to reverse oxidative stress (OS)-induced sperm dysfunction often encountered in this patient population. METHODS: A literature search was performed using MEDLINE/PubMed, focusing on publications of antioxidant therapies for iOAT. The main objective of our review article was to report the rationale and available evidence supporting the use of antioxidants...

INTRODUCTION: Oxidative stress (OS) is considered a significant contributor to male infertility. A number of laboratory techniques have been developed to evaluate oxidative stress in the semen. We review these tests and their current use. METHODS: A literature review was performed utilizing the PubMed search engine for articles studying OS etiology and impact on male fertility, and the laboratory tests used in its assessment. RESULTS: The state of OS results from exaggerated production of oxygen-derived free radicals, also known as reactive oxygen species, to an extent overwhelming the body's antioxidant defense mechanisms...

47,XYY syndrome is a sex chromosomal anomaly in men, which may be associated with infertility and has an incidence of 0.1% of male births. The clinical and paraclinical characteristics of men suffering from this anomaly have not been fully described. In this retrospective study, we present 37 cases of 47,XYY infertile men with sperm counts varying from normal to azoospermia, referred to the Genetics Laboratory at the Royan Institute, Iran. Thirteen individuals were mosaic and 24 non-mosaics. Non-mosaic patients were classified as azoospermic (nine cases) and normospermic/oligozoospermic men (15 cases)...

Aryl hydrocarbon receptor (AHR) is responsible for crucial events in male reproductive biology. Here, the association of the AHR transitions c.-742C>T and c.1661G>A with idiopathic male infertility was investigated in a case-control study, which is followed by a meta-analysis and a bioinformatic investigation. Blood and semen samples were obtained from a total of 135 idiopathic infertile men and 130 healthy controls. Participants were genotyped for the transitions using a PCR-RFLP method. A meta-analysis of five sets of data evaluated the association of c...

One hundred and seventy two men at the State of Thessaly, Greece, inquiring semen analysis were enrolled in the study in order to investigate the incidence of Chlamydia, Ureaplasma and Mycoplasma (C-U-M) genera in respect to total sperm number (TSN), progressive motility (grades a and b) and total motility (grades a, b and c). Putative relation of C-U-M acquirement with sexual behavior was also investigated. Incidence of C-U-M among non-oligozoospermic and oligozoospermic men was similar. Νο correlation of C-U-M carriage to either oligozoospermia or asthenozoospermia was found...
