BACKGROUND Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the hypothalamus-pituitary-testes axis, contributing to the regulation of male reproductive potential and overall wellbeing. These hormones are also present in semen influencing sperm functi...

Mercury is a toxic and bio-accumulative heavy metal of global concern. While good deals of research have been conducted on the toxic effects of mercury, little is known about the mechanisms involved in the pathogenesis of male reproductive dysfunction induced by mercury. Therefore, the purpose of this study was to assess the effects and underlying mechanisms of chronic mercury exposure at low l...

Coronavirus disease (COVID-19) can induce coagulopathy at the base of sepsis-induced coagulopathy (SIC), which is an important cause of death in these patients. Cytokine storm causes imbalance in coagulation and fibrinolytic system. A combination of hypercoagulability state, decrease or inhibition of fibrinolysis and endotheliopathy causes thromboembolic events. Underlying diseases such as diab...

Obesity is an uprising trend across the world resulting in huge costs for healthcare systems and declines quality of life patients. Bariatric surgery one most effective approaches to weight loss. Although bariatric can be considered as a minimally invasive approach it has series complications such regain 1 4 years after surgery. Nonetheless, patients achieve sufficient loss, but other subjects ...

Early obesity and late onset of insulin resistance associated with hormonal imbalances occur in FSH receptor-deficient follitropin receptor knockout female mice. This study tests the hypothesis that chronic high-fat diet aggravates obesogenic changes in a depot-specific manner and explores some molecular links of hormone imbalances with insulin resistance. In SV 129 mice, hormonal imbalances se...

Health[1] Health[1]Men's health [2]Norway [3]Forskning.no [4] There is a link between obesity and poor sperm quality. New research shows that fatty acids such as Omega3 may be an important explanation. Considering the fact that more and more people struggle with overweight and obesity, both in Norway and internationally, there is cause for concern, according to the researcher behind the study J...

In many species, including the dog (Canis familiaris), semen analysis protocols has improved in recent years. In vitro assessment of semen quality provides important information; however, the ultimate parameter for determining semen quality is pregnancy outcome. The objective of the present study was to investigate the efficiency of in vitro sperm tests in predicting seminal quality in dogs by ...

Semen is usually collected from bulls by use of an artificial vagina (AV) or by electroejaculation (EE). Semen collected by EE is often more dilute and may appear to be less motile than that collected by AV, although total sperm per ejaculate and sperm viability should be essentially similar (assuming the EE collection has been successful and complete). As fresh semen is very susceptible to env...

Inflammation and oxidative stress (OS) are closely related processes, as well exemplified in obesity and cardiovascular diseases. OS is also related to hormonal derangement in a reciprocal way. Among the various hormonal influences that operate on the antioxidant balance, thyroid hormones play particularly important roles, since both hyperthyroidism and hypothyroidism have been shown to be asso...

semen from six adult male black bengal goats (capra hircus) was collected to compare the fresh and frozen-thawed semen quality and investigate its relationship with the fertility. each collected samples was divided into two parts: one part of semen was used as fresh and another part was filled into 0.50 ml straws, sealed, cooled (5 ˚c) and equilibrated for freezing.in both cases, semen was dilu...
