INTRODUCTION The lipid composition of the sperm membrane has a significant effect on the functional characteristics of spermatozoa. PATIENTS AND METHODS In the present study, fatty acid composition of spermatozoa and seminal plasma levels of free 15-F(2t)-Isoprostane and catalase were assayed in men with normozoospermia, asthenozoospermia, asthenoteratozoospermia, and oligoasthenoteratozoospe...

The natural transmission of microdeletions of the Y chromosome is occasionally reported in the literature. Here we describe the natural transmission of a partial AZFb deletion over three generations. PCR amplification of several sequence tagged site markers in the three AZF regions of the Y chromosome was carried out in a patient with oligoasthenoteratozoospermia, his father and his naturally c...

Background Use of cellular phones emitting radiofrequency electromagnetic field (RF-EMF) has been increased exponentially and become a part of everyday life. This study aimed to investigate the effects of in vitro RF-EMF exposure emitted from cellular phones on sperm motility index, sperm DNA fragmentation and seminal clusterin (CLU) gene expression. MaterialsAndMethods In this prospective stud...

The latest micromanipulative technique, intracytoplasmic sperm injection (ICSI), has been very successful in cases of severe male factor infertility. The main objective of this study is to report the results of our fIrst experience with ICSI in cases of male factor infertility, as well as patients who had failed their previous cycles with conventional in vitro fertilization (IVF). Normal ...

A balanced translocation t(Y;16)(q11.21;q24) is described in a male with severe oligoasthenoteratozoospermia (OAT). Before having a chromosome investigation, the patient and his partner had undergone intracytoplasmic sperm injection (ICSI) treatment resulting in the birth of a healthy 46,XX child. After detection of the t(Y;16) translocation, the couple opted for further ICSI treatment, althoug...

PURPOSE A supernumerary marker chromosome (SMC) was analysed after lymphocyte culture of a patient with oligoasthenoteratozoospermia (OAT) before ICSI treatment. MATERIAL AND METHODS By additional molecular cytogenetic investigations the marker could be identified as a heterochromatic derivate of chromosome 15 [karyotype: 47,XY,+der(15)]. RESULTS Sperm analyses by interphase FISH showed a n...
