BACKGROUND It is generally accepted that oxidative stress is an important factor in male infertility because it may impair the physiological function of spermatozoa at the molecular level. Nevertheless, although several approaches have been reported, the imbalance between production of reactive oxygen species (ROS) and activity of the antioxidant defense system in semen is difficult to investig...

Background Leukocytes linked directly and indirectly to reactive oxygen species (ROS) formation. Although leukocytospermia is defined as the presence of ≥1×106 white blood cells/mL (WBC/mL) in a semen sample, the presence of less than 1×106 WBC/mL (low-level leukocytospermia) still can produce a detectable amount of ROS, impairing sperm function and lowering the chances of pregnancy. Low concen...

Oxidative stress is induced by reactive oxygen substances (ROS) that are known to affect male fertility. The aims of this study were to prospectively investigate and characterize total antioxidant and specifically polyphenols concentrations and their relations to sperm quality and fertility treatment success. During their infertility treatment, sixty-seven males were prospectively recruited to ...

CASE REPORT A 34-year-old man with a history of Crohn’s disease was referred to our department in July 2007 complaining of a decrease in ejaculated semen volume and pneumaturia for the past 2 months. He had previously undergone two perineal abscess drainage procedures (Seton’s method) in 2000 and 2007 due to perianal and ischiorectal abscesses arising from Crohn’s disease. His erectile function...

The Indian Dhat syndrome is a culture-bound symptom complex. The clinical picture includes severe anxiety and hypochondriasis. The patient is preoccupied with the excessive loss of semen by nocturnal emissions. There is a fear that semen is being lost, and mixed in urine. A study was carried out to investigate the cultural basis of the Dhat syndrome. One hundred and seven respondents from the g...

Perspectives of public health generally ignore culture-bound sexual health concerns, such as semen loss, and primarily attempt to eradicate sexually transmitted infections (STIs), including human immunodeficiency virus (HIV). Like in many other countries, sexual health concerns of men in Bangladesh have also received less attention compared to STIs in the era of AIDS. This paper describes the m...

To investigate the risk of transmission of hepatitis C virus (HCV) via semen in assisted reproduction techniques, semen samples from 32 men chronically infected with HCV attending a center for assisted procreation were tested for HCV RNA by a reverse transcription-PCR protocol by using a modified version of the Cobas AMPLICOR HCV assay (version 2.0; Roche Diagnostics). The sensitivity of the te...

BACKGROUND During the 2014-2016 West Africa Ebola Virus Disease (EVD) epidemic, the public health community had concerns that sexual transmission of the Ebola virus (EBOV) from EVD survivors was a risk, due to EBOV persistence in body fluids of EVD survivors, particularly semen. The Sierra Leone Ebola Virus Persistence Study was initiated to investigate this risk by assessing EBOV persistence i...

epididymal spermatozoa. The biological activity of the extracts seemed to result, at least in part, from their ability to prevent energy utilization by uncoupling oxidative phosphorylation (8, 11). More recently, it has been possible to separate the yeast fermentation stimulating activity from that which causes uncoupling of oxidative phosphory lation in rat kidney or liver preparations. In fre...

Background: The aim of present study was to estimate the levels of some Trace element (Lead, Copper, Cobalt, Chromium, and Cademium) concentrations in Asthenospermia and Normospermia by atomic absorption method, in comparison with control (Fertile), Estimate concentration of (MDA) Malondialdehyde and Total protein concentration in semen specimens.Also relationships between mentioned components ...
