Background: Approximately, one third of world's population older than 15 years of age smokes. Cigarette smoke contains toxic chemical, mutagenic and carcinogenic compounds. Some of these substances were found in seminal plasma.Over the past two decades, there has been an increasing body of evidence that cigarette smoking may impair human semen quality.The results of these studies are confl...

Several recent studies have shown that the fecundity of a man decreases progressively with sperm concentrations below 40 million spermatozoa per mL. Therefore, it is unfortunate that the new World Health Organization guidelines for semen analysis recommend lowering the lower cutoff value for normal sperm concentration from 20 to 15 million spermatozoa per mL. As a result large groups of subfert...

introduction: tegrity is the most important component for transferring genetic information sperm dna fragmentation is considered a component of male infertility. its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. in this study, we investigate the relationship between sperm parameters of motility, morphology, concentration, an...

BACKGROUND Besides the well-known adverse effects of valproate (VPA), disorders related to male reproductive functions have been reported. Furthermore, only a limited number of previous studies have reported the relationship between VPA dose and impairment of the hormonal axis and semen quality. A patient with reversible changes that occurred in the sperm parameters after a dose increment of VP...

AIM The present study was carried out on semen ejaculates of 15 Karan Fries (KF) bulls maintained at Artificial Breeding Research Centre, National Dairy Research Institute, Karnal, India with an objective to evaluate the relationship between the conventional and fluorescent based semen quality analysis of the bulls. MATERIALS AND METHODS A total of 96 ejaculates were collected from 15 KF (Hol...

The fertility rates of cryopreserved poultry semen are highly variable and not reliable for use in preservation of commercial genetic stocks. Our objective was to evaluate the cryosurvival of semen from 8 pedigreed layer lines at 2 different ages: the onset and end of commercial production. Semen from 160 roosters (20/line) was frozen individually with 11% glycerol at 6 and 12 mo of age. Glycer...

BACKGROUND/AIM The question of whether body mass index (BMI) affects semen quality and male fertility is controversial. The purpose of this research was to determine whether there is a correlation between BMI and semen analysis parameters. MATERIALS AND METHODS A total of 617 male infertility patients were recruited and separated into 3 groups according to BMI values as follows: normal weight...

Background: Although intrauterine insemination (IUI) is one of the most common methods which is used for male factor and unexplained infertility, the relative influence of various semen parameters on the likelihood of a successful outcome is controversial. Several semen parameters have been evaluated as predictors of a successful outcome with intrauterine insemination. Objective: To evaluate th...

Complimentary or natural antioxidant type of alternative medicine is developed worldwide to treat male infertility. The aim of this study is to the extraction of T. arjuna bark and activity against human sperm DNA damage in asthenoteratospermic smoker's subjects-an in vitro study. All preliminary and antioxidant assays (DPPH, H2O2, and total antioxidant, reducing power activity) were done. T. a...
