Objective: Exposure to heavy metals such as lead (Pb) results in oxidative stress induction in the male reproductive system. Herbal medicine can be utilized as antioxidant agents against oxidative stress. Quercus brantii (QB) has shown antioxidant activity in previous studies. The aim of the present study was to evaluate effects of QB hydro-alcoholic extract against Pb-induced oxidative stress ...

The effects of feeding a breeding diet containing soy products to pregnant and lactating females on reproductive tissues and secretion of the reproductive hormones in their male progeny, immediately after weaning (postnatal day - PND 22) and after reaching puberty (PND 60) were studied. Similarly, the response of adult males to a soy maintenance diet over shorter (PND 160) and longer (PND 280) ...

The advent of technologies to genetically manipulate the mouse genome has revolutionised research approaches, providing a unique platform to study the causality of reproductive disorders in vivo. With the relative ease of generating genetically modified (GM) mouse models, the last two decades have yielded multiple loss-of-function and gain-of-function mutation mouse models to explore the role o...

Among the small group of species (e.g., some temperate zone turtles, snakes, and bats) that exhibit a dissociated reproductive pattern, the red-sided garter snake (Thamnophis sirtalis parietalis) is probably the most well studied. For these species, courtship and mating occur immediately upon emergence from winter dormancy; the gonads remain essentially inactive. Male red-sided garter snakes ar...

background and aims: quantum dots (qds), as colloidal nanocrystalline semiconductors, present qd wavelengths in terms of biomedical assays and imaging, though the high toxicity of their core demands to be taken into consideration. investigating this subject is taken into account as an important concept   concerning use of these nanoparticles in the medical applications. materials and methods: 1...

An important part of male infertility of unknown etiology may be attributed to various environmental and occupational exposures to toxic substances, such as lead. The reproductive effects of lead are complex and appear to involve multiple pathways, not all of which are fully understood. It is still unclear, for example, if male reproductive issues in lead-exposed persons are mostly related to t...

Introduction: Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in females of reproductive age group. It characterised by menstrual irregularities, enlarged ovaries, infertility, high levels male hormones, excess hair on face and body, acne obesity. PCOS can result from abnormal function hypothalamic-pituitary-ovarian axis. Women with have an increased risk diabetes, bloo...
