to investigate the effect of two dietary levels of l-carnitine and vegetable fat powder on the quality of cockerels' sperm and broiler breeder fertility and hatchability. two hundred and fifty female and twenty five male broiler breeders. were studied classic hubbard parent stocks were randomly distributed in five groups of 50 with five replicates of 10 females and one male. two levels of ...

Background: Obesity and increased body mass index (BMI) affect the reproductive parameters in men such as poor semen quality, decreased sperm concentration, decreased normal-motile sperm cells and increased DNA fragmentation index. Lipid peroxidation contributes to the damage of the sperm plasma membrane. The Curcuma Longa is a resource of antioxidants, hence in this study also was evaluated th...

Background: Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children. Some studies have shown that increased body mass index is related to poor semen quality, decreased sperm concentration, decreased normal-motile sperm cells and increased DNA fragmentation index. Lipid peroxidation contributes to the damage of the sperm plasma membrane. Cinna...

Background: Obesity and raised body mass index (BMI) is a major risk factor for several diseases such as cardiovascular disease, type 2 diabetes, as well as gynecological problems. In recent years, some studies have associated the BMI with reproductive parameters in men, showing that increased BMI is related to poor semen quality, decreased sperm concentration, decreased and normal-motile sperm...

Background: Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer and infertility and dub fertility. Some studies have associated the body mass index (BMI) with reproductive parameters in men, showing that increased BMI is related to poor semen quality, decreased sperm concentration, decreased normal-m...

The effects of ingestion of protein deficient or protein supplemented diets with or without sodium fluoride (NaF, 5, 10, and 20 mg/kg body wt) were studied on sperm function in mice and compared with effects on mice fed a control (standard) protein diet + NaF in the above three dose levels for 30 days. Ingestion of the protein deficient diet together with the three dose levels of NaF caused a s...

Background: Vitamin E is believed to be the primary component of the antioxidant system in spermatozoa. There is a relationship between activity of these antioxidant and function of sperm. Vitamins E and C which are belong to non-enzymatic antioxidant are used as a supplemented drug to improve sperm quality and male fertility. The present study was carried out to investigate the positive effect...

background: high level of semen reactive oxygen species is considered as an important factor in male infertility. sesame has antioxidant properties, which could be effective on improvement of semen parameters. this study was designed to determine the effects of sesame on sperm quality.   materials and methods: twenty‑five infertile men entered this clinical trial. they were treated with a 3â€...

BACKGROUND Oligoasthenoteratozoospermia (OAT) syndrome is the most frequently seen phenotype in male infertility. Spermatogenesis relies closely on hormone regulation. The aim of this study was to assess the correlation between hormone profile and semen parameters in infertile men with idiopathic or varicocele-related OAT syndrome. We tried to illustrate the correlative factors for better semen...

Background: Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems such as infertility and sub fertility. Lipid peroxidation contributes to the damage of the sperm plasma membrane and result to infertility. In this study effects of Antioxidants (E, C, ...
