Lead is the known environmental contaminant adversely affecting the male reproductive system in human and experimental animals. The cytotoxic effects of lead on male reproductive system involve the production of reactive oxygen species (ROS) and oxidative damage in tissue. The higher quantities of ROS in testicular tissue detrimentally affected developing germ cells so as to produce verities of...

BACKGROUND Indomethacin is a member of non-steroidal anti-inflammatory drugs (NSAIDs) commonly used for treatment of gout, arthritis, and other inflammatory conditions. It has been shown to inhibit ovarian prostaglandins synthesis in mammals, birds, fish and reptiles. However, the effects of its chronic administration on male reproductive functions remain largely unknown. Using rat as a model, ...

Ewes randomly assigned into groups including Group A Control (base diet recipient), B (Flushing), C (Flushing + Vitamin E Supplement Organic Selenium), and D Mineral Selenium). Blood sampling was carried out at different intervals na...

conclusions according to the results of this study, vitamin e probably improves the harmful effects of formaldehyde on rat kidney tissue. results comparison of the control and formaldehyde groups with the vitamin e group revealed that there were significant differences in lumen size and nuclear color of proximal tubules in rats treated by vitamin e (p < 0.05). cell degeneration, lumen size, num...

gibberellic acid (ga3) is a group of plant hormones identified in various plants. the aim of this study was to determine the effects of ga3 on sperm parameters and in vitro fertilization (ivf). fifty six adult male rats were divided into seven groups as, control, treatment and sham. following 15, 30 and 45 days of ga3 and methanol alcohol (ma) administration, rats were euthanized and epididymis...

Various studies have revealed the effects of vitamin B12, also named cobalamin, on semen quality and sperm physiology; however, these studies collectively are still unsummarized. Here, we systematically discuss and summarize the currently understood role of vitamin B12 on semen quality and sperm physiology. We searched the Web of Science, PubMed, and Scopus databases for only English language a...
