I-16: Computer Aided Sperm Analysis andSperm Functional Testing (Hyperactivation) asBackground Tools in the Evaluation of SpermFunction/Quality

After twenty years Computer Aided Sperm Analysis has developed considerably and is now routinely used in many laboratories across the world. The advantage of the CASA methodology available is twofold: Analysis of particularly sperm concentration, sperm motility, sperm morphology and vitality is quantified in an Background manner. Secondly, most of the CASA analysis with the exception of sperm m...

Should sperm DNA fragmentation testing be routinely used in assessing male infertility?

Semen analysis (SA) is the cornerstone for male infertility evaluation. Variations in sperm quantity and quality may make SA an unreliable decision-making tool in providing an insight of infertility (1). Consequently, efforts have been made to upgrade techniques of male fertility analysis. In recent times, primary investigative techniques have centered around assessing sperm capacity, sperm fun...

Human Sperm Aster Formation and Chromatin Configuration in Rabbit Oocytes Following Intracytoplasmic Sperm Injection Using a Piezo-Micromanipulator

In human fertilization, the sperm centrosome nucleates a radial array of microtubules called the sperm aster. The sperm aster is responsible for apposition of male and female pronuclei, and later gives rise to the first meiotic spindle. The objective of this study was to determine microtubule assembly and chromatin configuration in rabbit oocytes following intracytoplasmic injection with human ...

Human sperm bound to the zona pellucida have normal nuclear chromatin as assessed by acridine orange fluorescence.

BACKGROUND The aim of this study was to determine if only sperm with double stranded DNA could bind to the human zona pellucida (ZP). METHODS Sperm samples from 124 infertile men with a range of semen abnormalities were studied. Oocytes that had failed to fertilize in IVF or ICSI were used for the sperm-ZP binding test. A group of four oocytes were incubated for 2 h with 2 x 10(6)/ml motile s...

Ejaculate-hormonal traits in the leopard cat (Felis bengalensis) and sperm function as measured by in vitro penetration of zona-free hamster ova and zona-intact domestic cat oocytes.

Electroejaculate traits and circulating follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone concentrations were analyzed in adult leopard cats (Felis bengalensis), a rare felid species indigenous to east Asia. The ability of leopard cat sperm to bind and penetrate zona-free hamster ova and zona-intact domestic cat oocytes in vitro was examined as a means of testing sp...

Effect of electromagnetic irradiation produced by 3G mobile phone on male rat reproductive system in a simulated scenario.

Reports of declining male fertility have renewed interest in assessing the role of electromagnetic fields (EMFs). Testicular function is particularly susceptible to the radiation emitted by EMFs. Significant decrease in sperm count, increase in the lipid peroxidation damage in sperm cells, reduction in seminiferous tubules and testicular weight and DNA damage were observed following exposure to...
