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),...

BACKGROUND Recently, motile sperm organelle morphology examination (MSOME) criteria as a new real time tool for evaluation of spermatozoa in intracytoplasmic sperm injection (ICSI) cycles has been considered. OBJECTIVE The aim was to investigate the predictive value of MSOME in in vitro fertilization (IVF) in comparison to ICSI cycles and evaluation of the association between MSOME parameters...

pressure refers to the feelings an athlete has about performing in a competitive situation. the primary aim of this study was to examine kinematic changes of tennis serves in increasing competitive pressure. 20 semi-professional right-handed male tennis players completed 120 serves under low (normal) and high competitive pressure phases. pressure checks (heart rate and perceived competitive sta...

The plasma membrane is a key organelle with respect to sperm fertilizing ability. A sensitive way of testing plasma membrane functionality is to examine the sperm ability to moderate its swelling in response to hypo-osmotic stress (volume regulatory ability) using an electronic cell counter to assess cell volume changes. In this study of frozen-thawed bull sperm, we examined the relationship am...

Precise teleoperation of deztrous robotic hands b y hand masters requires an accurate human hand model. A kinematic model of a human index finger is developed as an example for human hand modeling. The parameters of the model are determined b y open-loop kinematic calibration. Singular value decomposition is used as a tool for analyzing the kinematic model and the identification process. Accura...

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 Sperm quality, including semen volume, sperm count, concentration, and total progressive motility (collectively, “semen parameters”), has declined in the recent decades. Computer-assisted analysis (CASA) provides kinematic parameters, temporal trends of which remain unclear. Our objective is to examine trend both parameters Shanghai, China, years. Methods This retrospective study ana...

background: one of the main laboratory tests for evaluation of infertility is semen analysis (sa). however additional tests may be suggested for further diagnosis of male fertility potentials. the seminal fluid contains sperms non-sperm cells and various types of lipids and glucose. objective: the objective of this cross-sectional study was to correlate the sperm parameters with concentrations ...

background: bleomycin (bl) is a glycopeptide antibiotic obtained from the bacterium streptomyces verticillus which is routinely used for treatment of human cancers. royal jelly (rj) is a production from the hypo pharyngeal, mandibular and post cerebral glands of nurse bees. rj consists of 66% water, 15% sugars, 5% lipids, and 13% proteins, essential amino acids and vitamins. objective: the aim ...
