Reproductive toxicity of Roundup herbicide exposure in male albino rat
Abstract: The incidence of infertility in human is on the increase and the use of Roundup herbicide and presence of its residues in foodstuff is a major concern. This study therefore aim to assess the effect of Roundup on the reproductive capacity of 32 adult male albino rats randomized into 4 groups of 8 rats …
Reproductive performance of alternative male phenotypes of growth hormone transgenic Atlantic salmon (Salmo salar)
Abstract: Growth hormone (GH) transgenic Atlantic salmon (Salmo salar) is one of the first transgenic animals being considered for commercial farming, yet ecological and genetic concerns remain should they enter the wild and interact reproductively with wild fish. Here, we provide the first empirical data reporting on the breeding performance of GH transgenic Atlantic salmon …

Climate change alters reproductive isolation and potential gene flow in an annual plant
Abstract: Climate change will likely cause evolution due not only to selection but also to changes in reproductive isolation within and among populations. We examined the effects of a natural drought on the timing of flowering in two populations of Brassica rapa and the consequences for predicted reproductive isolation and potential gene flow. Seeds were …
Occupational exposure to pesticides, reproductive hormone levels and sperm quality in young Brazilian men
Abstract: The association of occupational exposure to current-use pesticides with reproductive hormones, semen quality, and genital measures was investigated among young men in the South of Brazil. A cross-sectional study was conducted in 99 rural and 36 urban men aged 18–23 years. Information on pesticide use was obtained through questionnaire. Serum and semen samples were …
Perinatal exposure to a glyphosate-based herbicide impairs female reproductive outcomes and induces second-generation adverse effects in Wistar rats
Abstract: Glyphosate-based herbicides (GBHs) are the most globally used herbicides raising the risk of environmental exposition. Here, we investigated whether perinatal exposure to low doses of a GBH alters the female reproductive performance, and/or induced second-generation effects related to congenital anomalies or growth alterations. Pregnant rats (F0) received a GBH through food, in a dose …
Potential gene flow from transgenic rice (Oryza sativa L.) to different weedy rice (Oryza sativa f. spontanea) accessions based on reproductive compatibility
Abstract: BACKGROUND: The possibility of gene flow from transgenic crops to wild relatives may be affected by reproductive capacity between them. The potential gene flow from two transgenic rice lines containing the bar gene to five accessions of weedy rice (WR1–WR5) was determined through examination of reproductive compatibility under controlled pollination. RESULTS: The pollen grain …
Pathological changes of reproductive ability pigs long-term feeding roundup ready genetically modified soy
Abstract: Introduction. Genetically modified soy is characterized by a high protein content (38-42%), which contains all the essential aminoacids, many polyunsaturated fatty acids, vitamins, macro and micronutrients, so it comprise of many foods: bread, biscuits, margarine, pizza, sausage, candy, milk, yogurt, baby food and others, but the final opinion on their safety there. This problem …
Environmental exposure to glyphosate and reproductive health impacts in agricultural population of Argentina
Abstract: Argentina annually utilizes 240,000 tones of glyphosate in industrial agriculture and a change in the profile of morbidity is perceived for physicians of agricultural areas; now reproductive disorders seem to prevail. The objective of this study is to determine concurrence of glyphosate exposure and reproductive disorders in a typical argentine agricultural town (Monte Maíz). An …
Glyphosate impairs male offspring reproductive development by disrupting gonadotropin expression
Abstract: Sexual differentiation in the brain takes place from late gestation to the early postnatal days. This is dependent on the conversion of circulating testosterone into estradiol by the enzyme aromatase. The glyphosate was shown to alter aromatase activity and decrease serum testosterone concentrations. Thus, the aim of this study was to investigate the effect …
Effect of Roundup® (glyphosate formulation) in the energy metabolism and reproductive traits of Hyalella castroi (Crustacea, Amphipoda, Dogielinotidae)
Abstract: Roundup® (glyphosate formulation) is a nonselective and posts emergent herbicide used for controlling aquatic weeds and different concentrations are used in cultures around the world. The objective of this investigation was to examine the effects of Roundup® (glyphosate formulation) on the biochemical composition, levels of lipoperoxidation, Na+/K+ATPase activity and reproductive traits in the Hyalella …
One species to another: Sympatric Bt transgene gene flow from Brassica napus alters the reproductive strategy of wild relative Brassica juncea under herbivore treatment
Abstract: Since pollen flow or seed dispersal can contribute to transgene persistence in the environment, the sympatric presence of transgenic crops with their wild relatives is an ecological concern. In this study, we tested the hypothesis that proximate growth of a herbivore-resistant Bt crop and wild relatives coupled with the presence of herbivores can increase …
Intensity of growth and reproductive ability of pigs at conditions of consuming GM-soya
Abstract: Soya takes one of leading place in the balance of protein fodder cultures and in its grain there is a high contains of protein. Its amino acids composition is the most approximate to feed-staffs of animal origin. Considerable percent of sowing areas are allocated under high-yielding and technological genetic-modified lines of soya which is …
Effect of soy diet on reproductive function and testosterone levels in rats and hamsters
Text: Влияние диеты, содержащей генетически модифицированную (ГМ) сою, на репродуктивные функции животных изучено недостаточно. Имеющиеся в литературе данные противоречивы. Так, Brake и Evenson [1] не выявили негативного воздействия наиболее распространенной ГМ-сои устойчивой к гербициду раундапу в результате внедрения трансгена EPSPS CP4 (RR, линия 40.3.2), на сперматогенез у потомства самцов мышей. В то же время в …
Study of reproductive function in persons occupationally exposed to 2,4-dichlorophenoxyacetic acid (2,4-D)
Abstract: We studied the reproductive function of 32 male farm sprayers who were exposed to 2,4-D. Sperm analysis was made after 4 days of sexual inactivity. Parameters analyzed were volume, sperm count, mobility and morphology. Exposure level was estimated by measuring the concentration of 2,4-D in the urine. Significant levels of asthenospermia, necrospermia and teratospermia were …
Effects of glyphosate-based herbicides on reproductive features of guppies (Poecilia reticulata)
Abstract: Human population grows in bigger proportions then food production worldwide. To solve this problem, increase food production is required. Agriculture has potentialized food production through pesticides usage. Besides that, GMO’s increase production and usage of glyphosate based herbicide (HBG), since this product does not affect GMO’s. HBG’s have many side effects on non-target animals, …
