OBJECTIVE To investigate, in men presenting with recurrent pregnancy loss (RPL), the prevalence of sperm autosome and sex chromosome aneuploidy. DESIGN Retrospective study. SETTING Male infertility clinic. PATIENT(S) A total of 140 men with RPL provided semen samples, and five normozoospermic controls provided 140 semen samples for comparison. Recurrent pregnancy loss, documented in the f...

The yield of flow cytometric sorted Xand Y-chromosome-bearing sperm in a given time period is an important factor in the strategies used for fertilization and the production of sex-preselected offspring. This yield is dependent on the efficiency with which the modified flow cytometer/cell sorter analyzes the DNA of spermatozoa. The efficiency is directly related to the number of sperm with the ...

BACKGROUND Sperm membrane integrity is not only important as a barrier between intra- and extra-cellular spaces, but also it can be considered as a sign of DNA integrity. Hypoosmotic swelling test reflects membrane integrity and has been used to evaluate sperm quality. Intracytoplasmic sperm injection (ICSI) in adjunct with hypo-osmotic swelling test (HOST) has been used for treatment of males ...

context air pollution is common in all countries and affects reproductive functions in men and women. it particularly impacts sperm parameters in men. this meta-analysis aimed to examine the impact of air pollution on the quality of sperm. conclusions the results of this meta-analysis showed that air pollution reduces sperm motility, but has no impact on the other sperm parameters of spermogram...

conclusions sperm quality extracted by percutaneous pesa and tese procedures increases fertility outcomes compared to naturally ejaculated sperm in men with idiopathic co. more specifically, embryo quality, which is most relevant to fertility outcome, improved when surgically extracted sperm was used for icsi. results there was a significant difference in fertilization rate, embryo quality, imp...

the freezing and thawing process not only is associated with serious damage to sperm such as damage to the plasma membrane and the acrosomal membrane but also changes the membrane permeability to some ions including calcium. also, the generation of oxygen free radicals is increased during the freezing-thawing process. the purpose of this study was to evaluate of the effects of trolox as an anti...

OBJECTIVE: The present study aimed to know the effect of paternal age together with Sperm DNA fragmentation on clinical and laboratory outcomes in donor oocyte intracytoplasmic sperm injection cycles. STUDY DESIGN: In this prospective cohort a total 229 patients undergoing their first cycles fresh blastocyst embryo transfer oocytes were included study. All categorized into four groups based mal...

Repeated semen specimens from healthy men were analyzed by sperm fluorescence in situ hybridization (FISH), to identify men who consistently produced elevated frequencies of aneuploid sperm and to determine whether men who were identified as stable variants of sperm aneuploidy also exhibited higher frequencies of aneuploidy in their peripheral blood lymphocytes. Seven semen specimens were provi...
