metronidazole and it’s derivatives are drugs that have both antiprotozoal and anti bacterial effect.the reproductive toxicity of metronidazole has been shown in some studies. to investigate the effect of metronidazole on spermatogenesis in adult male rats, this study was designed. eighteen wistar male rats (70-90days old) were randomly divided into three groups. animals in group i (control grou...
Background: Inactivation of transcription occurs during two phases of spermatogenesis. First, in spermatocytes entering the primary meiosis and the second in round and elongating spermatids. These stages of inactivated transcription demand extensive regulation of translation. Therefore, presence of the control on gene expression during spermatogenesis seems essential. In the cases that post-tra...
The ADP-ribosyltransferase 3 gene (ART3) has been reported to be associated with non-obstructive azoospermia (NOA) in the Japanese population. In this study, we aim to explore the possible association between the four single nucleotide polymorphisms (SNPs) (rs11097230, rs17001385, rs14773 and rs6836703) in ART3 gene and male infertility with spermatogenesis impairment in the Chinese population....
Oxidative stress can contribute to impairment in spermatogenesis leading to male-factor infertility. The effectiveness of various antioxidants (such as carnitine, vitamin C, vitamin E, selenium, carotenoids, glutathione, N-acetylcysteine, zinc, folic acid, and coenzyme Q10) is variable with respect to improving semen parameters and pregnancy rates. A recent Cochrane review determined that men t...
Guinea pig testicles were extracted with acetic acid; the extract was purified by removing material in consecutive precipitations with 30 per cent saturated ammonium-sulfate, trichloracetic acid, and chloroform. The solution so purified, when administered with complete adjuvants, was highly active in inducing impairment of spermatogenesis in guinea pigs. The activity resisted autoclaving at 15 ...
