Cyperus esculentus L. protects testis and sperm morphology of hyperglycaemic rats

Cyperus esculentus L. (tiger nut) is a tuberous plant that promotes and protects reproductive functions, which are usually hampered in diabetics. The present study investigated the effect of Cyperus esculentus tuber extract (CETE) on testicular histology and sperm viability of all...

The combined effect of lifestyle intervention and antioxidant therapy on sperm DNA fragmentation and seminal oxidative stress in IVF patients: a pilot study

Int. braz. j. urol; 48 (1), 2022
ABSTRACT Purpose: Sperm DNA fragmentation (SDF) and seminal oxidative stress are emerging measurable factors in male factor infertility, which interventions could potentially reduce. We evaluated (i) the impact of lifestyle changes combined with oral antioxidant intake on sperm DNA fragmentation index (...

The benefit of Silybum marianum in ethanol-induced reprotoxicity of male Wistar rat

Abstract This study investigates the toxic effects of ethanol (Eth) on the reproductive system of male rats and the possible protective role of Silybum marianum seeds-infused solution (SMI) over six consecutive weeks of administration. Animals were divided into the following groups: control, SMI positive...

Ameliorative effects of morel mushroom (Morchella esculenta) against Cadmium-induced reproductive toxicity in adult male rats

Braz. j. biol; 82 (), 2022
Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (...

Efecto del consumo de marihuana sobre los parámetros espermáticos humanos: Aproximación in vivo

La evidencia sugiere que la exposición a sustancias psicoactivas se relaciona con alteraciones en la espermatogénesis que afectan la calidad espermática. El objetivo de este trabajo fue determinar los parámetros espermáticos en consumidores habituales de cigarrillos de marihuana. Se analizaron muest...

Sperm DNA damage compromises embryo development, but not oocyte fertilisation in pigs

Biol. Res; 55 (), 2022
BACKGROUND: The assessment of sperm DNA integrity has been proposed as a complementary test to conventional mammalian semen analysis. In this sense, single-strand (SSB) and double-strand (DSB) DNA breaks, the two types of sperm DNA fragmentation (SDF), have been reported to have different aetiologies and...

The Effect of Glyphosate on Human Sperm: In Vitro Approximation

Introduction Glyphosate is an herbicide used to eradicate illicit crops; however, its use is controversial due to different health problems associated with it. The present study aims to evaluate the effects of glyphosate on human sperm in vitro. Methods Twenty-two semen samples from healthy normozoos...
