OBJECTIVE: The aim of our study was to identify the prevalence of HPV in the semen of men submitted to ART treatment and look into the possible impacts of the virus on sperm parameters. METHODS: Thirty-five patients treated for infertility from March to August 2016 were invited to join the study. Samples with a minimum concentration of 40x106 spermatozoa per milliliter were included in the study. After the evaluation of semen parameters, DNA extraction and PCR were performed to verify the presence of HPV by electrophoresis in 8% polyacrylamide gel...

The major purpose of the present study was to investigate the efficacy and feasibility of the Mullerian duct cyst treatment by transurethral electrotomy combined with seminal vesiculoscopy. The clinical data of 20 aspermia patients who presented with Mullerian Cyst between March 2009 and March 2016 were retrospectively analyzed in the present study. Semen specimens of all patients were obtained by masturbation or sperm collector and diagnosed as aspermia by semen analysis (including sperm count, semen volume, sperm density, pH and fructose level)...

Reproductive performance in aged broiler breeder roosters is not desirable. The purpose of this study was to assess the effects of dietary flaxseed oil and vitamin E on the semen parameters, hormonal profiles, fatty acid analysis of sperm, and fertility performance of aged roosters. Twenty four roosters were assigned into four treatments and received their diets as following: 1) basal diet as control group (CTRL), 2) basal diet supplemented with 200 mg/kg vitamin E (CTRL + VITE), 3) basal diet supplemented with 2% flaxseed oil (FLAX) and 4) basal diet supplemented with 2% flaxseed oil plus 200 mg/kg vitamin E (FLAX + VITE)...

BACKGROUND: Multiple health problems have been reported in survivors of Ebola virus disease (EVD). Attribution of these problems to the disease without a control group for analysis is difficult. METHODS: We enrolled a cohort of EVD survivors and their close contacts and prospectively collected data on symptoms, physical examination findings, and laboratory results. A subset of participants underwent ophthalmologic examinations. Persistence of Ebola virus (EBOV) RNA in semen samples from survivors was determined...

Relationship of scrotal bifurcation or splitness with breeding soundness traits was investigated in 15 Beetal bucks (17-20 months of age and 48.72 ± 1.57 kg mean BW). Breeding soundness traits of conjoined/unsplit (n = 6) scrotal bucks was compared with split (n = 9) scrotal bucks having lengthwise > 1 in. bifurcation. Two consecutive semen ejaculations per buck were collected at monthly interval during summer season (April to June 2018) using intact buck as teaser and sexual behavior was simultaneously recorded...

OBJECTIVE: Studies showed a decrease of the semen analysis parameters and an increase in the average age of first-time fathers over the past several decades. The aim of the present study was to assess the influence of paternal age on semen quality and fertilization outcomes in men with normal sperm DNA fragmentation and chromatin maturation index (DFI and CMI), reactive oxygen species (ROS), and total antioxidant capacity (TAC) levels.

Seminal oxidative stress (OS) is a major cause of male factor infertility and can be measured as oxidation-reduction potential (ORP). Studies showed significant negative relationships of ORP with sperm count, motility or DNA integrity. Since these parameters are also positively or negatively associated with reproductive hormones follicle-stimulating hormone (FSH), luteinising hormone (LH), testosterone, testicular volume and the occurrence of varicocele, it is important to understand the mechanistic relationship between ORP and hormonal and/or testicular parameters...

BACKGROUND: While the spermatotoxic properties of cancer treatments such as chemotherapy and radiation therapy are widely recognized, the effect of malignancy itself on male fertility is not clearly understood. OBJECTIVES: To determine whether malignancy is associated with diminished semen quality prior to spermatotoxic treatment among sperm bankers. MATERIALS AND METHODS: Retrospective database review of de-identified records was obtained for all episodes of sperm banking performed at a cryobank from January 2004 to May 2017 for one of the following reasons: 'future use' (e...

Following the largest Ebola virus disease outbreak from 2013 to 2016, viral RNA has been detected in survivors from semen and breast milk long after disease recovery. However, as there have been few cases of sexual transmission, it is unclear whether every RNA positive fluid sample contains infectious virus. Virus isolation, typically using cell culture or animal models, can serve as a tool to determine the infectivity of patient samples. However, the sensitivity of these methods has not been assessed for the Ebola virus isolate, Makona...

Varicocelectomy is associated to improved semen quality and sperm functional quality, but individual response is highly variable. Thus, a prospective study was performed including 25 men who collected a semen sample before and 12 months after subinguinal microsurgical varicocelectomy. Semen analysis, sperm functional analysis, and seminal plasma proteomic analysis was performed before and 12 months after varicocelectomy, and according to improvement or not of semen quality (positive and negative outcome)...

Sperm banking and AI could benefit endangered African wild dog conservation. However, it is unclear whether their dominance hierarchy causes a decrease in reproductive and sperm quality parameters in subordinate males that typically do not breed. In this study, we investigated the effect of social rank on male reproductive parameters, including faecal androgen and glucocorticoid metabolite concentrations, prostate and testes volume, preputial gland size, semen collection success and sperm quality. Samples were obtained from captive males (prebreeding season: n=12 from four packs; breeding season: n=24 from seven packs) that were classified as alpha (dominant), beta or gamma (subordinates) based on the frequency of dominant versus submissive behaviours...

Evidence from previous studies has shown that phthalates may play a role in male reproductive function; however, results are still inconclusive, and the mechanism remains unclear. In this study, we first assessed whether exposure to phthalates is associated with altered reproductive hormones and semen parameters in 599 men attending an in vitro fertilization clinic. Secondly, we evaluated whether reproductive hormones could play a mediating role in the association between phthalates and sperm parameters. Eight phthalate metabolites were measured in two different spot urine samples: mono‑n‑butyl phthalate, mono-isobutyl phthalate (MiBP), monoethyl phthalate (MEP), monobenzyl phthalate, and four oxidative metabolites of di‑(2‑ethylhexyl) phthalate (DEHP) [i...
