The data published on the modifications of amino-acid metabolism associated with variations of obesity from genetic or hormonal origin have been reviewed. In the first part monogenic models of mice and rats are described. Obesity in humans is analysed in the second part. Lastly, non-ruminant genotypes or hormone-treated ones (chickens and pigs) are reviewed in the third part. Although different...

Artificial insemination is nowadays a widely used technique for the enhancement of genetic potential of livestock species. But still the maximum benefit of this tool cannot be extracted as there are certain inherent problems of semen quality like poor semen quality and poor freezability with crossbred and buffalo bulls. Correspondingly, there is a genetic and economic loss owing to disposal of ...

INTRODUCTION Infertility affects approximately 15% of all couples, and male factor contribute to up to 50% of cases. Unfortunately, the cause of male infertility is unknown in about 30% of these cases. Infertility of unknown origin is classified as idiopathic male infertility when abnormal semen parameters are present. Despite not having a definable cause, these men may respond to treatment. Th...

Abstract Background The global prevalence of obesity has soared to a concerning height in the past few decades. Interestingly, decline semen quality is parallel occurrence that urges researchers evaluate if among most essential causatives male infertility or subfertility. Main body Obesity may alter synchronized working reproductive-endocrine milieu, mainly hypothalamic-pituitary-gonadal (HPG) ...

Obesity has become one of the major threats for public health in industrialised world among adults, but also among adolescents and children. It is influenced by the interaction of genes, nutrition, environment, and lifestyle. Environmental and lifestyle risk factors include foetal and lifelong environment, nutrient quality, chemical and microbial exposure, and psychical stress, all of which are...
