Background Fertility disorder is a multifaceted physiopathological condition comprising men’s or women’s impotence in fertility or a combination of both. Men’s debility in fertilization is the main culprit in 40-50 percent of the studied cases. The first step in scrutinizing infertility is to analyze semen. So, the assessment hinges on analyzing factors like sperm density, total count and motil...

BACKGROUND High isoflavone intake has been related to decreased fertility in animal studies, but data in humans are scarce. Thus, we examined the association of soy foods and isoflavones intake with semen quality parameters. METHODS The intake of 15 soy-based foods in the previous 3 months was assessed for 99 male partners of subfertile couples who presented for semen analyses to the Massachu...

The aim of this study was to evaluate the outcomes of multiple advanced surgical treatments (i.e. microsurgery, laparoscopic surgery and endoscopic surgery) for acquired obstructive azoospermia. We analyzed the surgical outcomes of 51 patients with suspected acquired obstructive azoospermia consecutively who enrolled at our center between January 2009 and May 2013. Modified vasoepididymostomy, ...

PURPOSE To elucidate the impact of surgical varicocele repair on the pregnancy rate through new meta-analyses of randomized clinical trials that compared surgical varicocele repair and observation. MATERIALS AND METHODS The PubMed and Embase online databases were searched for studies released before December 2012. References were manually reviewed, and two researchers independently extracted ...

We designed prospective studies to compare manual and computerized analysis of sperm morphology by strict criteria using different semen processing and staining techniques. A total of 54 semen samples were studied; slides were prepared from each subject from liquefied semen and after washing, and stained with Diff-Quik or Papanicolaou. An intra-laboratory, blind assessment was performed manuall...

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 v...

BACKGROUND One of the major obstacles in using artificial insemination to manage genetics of elephant population in captivity is the large variations in semen quality among ejaculates within the same and among individuals. The objectives of this study were to determine the influences of (1) age (2) seasonality (3) and circulating testosterone (SrTest), triiodothyronine (SrT3) and tetraiodothyro...

the aim of this study was to evaluate the effects of the addition of antioxidants (vitamin e, β- mercaptoethanol and their combination) to semen extender.  progressive motility, viability and ph of fresh ram semen were examined. ejaculate samples were collected with artificial vagina from three ghezel-merinose rams (3 years old) during non- breeding reproduction season. semen was diluted with a...

Background: Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology of diverse male infertility types, including asthenospermia. The generation of reactive oxygen species (ROS) in the male reproductive tract has become an actual concern because of their probable noxious effects, at high levels, on physical properties of sperm ...
