Background: It is shown that hypertension may affect androgens. The role of blood pressure on sperm parameters is matter of debate. The main goal was to evaluate the probable association between systolic and diastolic blood pressure and sperm parameters. Materials and Methods: Semen Sample of men (aged: 27- 45 years old) from 40 infertile cases who attended at Yazd research and clinical center ...

Computer-assisted semen analysis (CASA) is an automated and objective method of evaluating structural (e.g. morphology) functional sperm parameters motility hyperactivation). Sperm hyperactivation essential for successful fertilization thus important aspect in determining the fertility potential a male. In current study, CASA was used standard comparison ability phosphate buffered saline (PBS),...

Seminal plasma characteristics, such as ionic composition and pH, are important for sperm maturation further motility. In this work, a first batch of experiments evaluated the effect absence several ions (Na+, K+, Mg2+) in artificial seminal plasma, well pH seawater on activation pufferfish (Takifugu alboplumbeus, named before Takifugu niphobles). all experiments, total motility, progressive cu...

Background The quality of semen depends upon several factors such as environment, life style, physical activity, age, and occupation. The aim of this study was to analyze and compare the conventional and functional semen parameters in men practicing vigorous physical activity to those of sedentary men. MATERIALS AND METHODS In this descriptive cross-sectional study, semen samples of 17 physic...

OBJECTIVE To evaluate the impact of antegrade scrotal sclerotherapy on seminal parameters and pregnancy rates in varicocele patients who have impairment of seminal parameters and/or couple infertility. DESIGN Longitudinal, noncomparative study. SETTING Tertiary university hospital. PATIENT(S) Three hundred sixty-four consecutive varicocele patients with seminal impairment, including 173 (...

Bothrops insularis is an endemic and critically endangered snake with an estimated population of 2000 individuals restricted to Queimada Grande Island, in southeastern Brazil. Brazilian researchers established a captive breeding program for the species that includes the application of assisted reproductive technologies. The present study, therefore, aimed to evaluate semen samples from captive ...

Male infertility is a worldwide medical problem. Asthenozoospermia is a common cause of infertility. Epigenetic modifications of DNA and histones have been shown to influence human infertility, but no research has explored whether N(6)-methyladenosine (m(6)A) level in RNA is associated with asthenozoospermia. Here, we collected a total of 52 semen samples, including 20 asthenozoospermia patient...

The present study was performed to compare the expression of sperm proteins, i.e. triosephosphate isomerase (TPI) and acrosin binding protein (ACRBP) seminal plasma glutathione peroxidase 5 (GPX5) fibronectin 1 (FN1), in boar semen with good, moderate poor freezability. conducted by determining contents 32 samples 38 semen. ejaculated divided into two portions: first portion centrifuged separat...

BACKGROUND A bulk of contraceptives on the market is women-oriented today. The aim of this study was to investigate the effect of a medicinal herb, Acacia nilotica on various parameters of male fertility using a rat model. METHODS Male Wistar rats (n = 40) were randomly divided in to two groups. One group received Acacia nilotica, while the other acted as controls. Ten animals from each group...
