OBJECTIVE To examine the effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility. Prospective study. SETTINGS Infertility clinic at a tertiary care academic institution. PATIENT(S) Ninety-two infertile men with normal female partners. Sixteen fertile donors served as the control group. INTERVENTION(S) Standard semen ...

background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...

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. MATERIALS AND METHODS In this prospective ...

To evaluate the best method for sperm separation in high DNA fragmentation index (DFI) samples. A prospective randomised study was conducted from 1st January 2019 to 2021. Three hundred patients were by computer generated list and divided into 3 groups. Group (n=100) , which processed microfluidic sorter (MFSS) while group B (n=100), selected Physiological Intracytoplasmic Sperm Injection (PICS...

BACKGROUND The aneuploidy rate is higher in poor-quality sperm samples, which also have higher DNA fragmentation index values. The aim of this study was to assess the relationship between sperm DNA fragmentation in samples from infertile men belonging to couples with recurrent miscarriage or implantation failure and the aneuploidy rate in spermatozoa as well as in embryos from patients. METHO...

background: oxidative stress in teratozoospermic semen samples caused poor assisted reproductive techniques (art) outcomes. among antioxidants, ascorbic acid is a naturally occurring free radical scavenger and as such its presence assists various other mechanisms in decreasing numerous disruptive free radical processes. objective: the main goal of this study was to evaluate potential protective...

background: heat shock protein a2 (hspa2) is correlated with sperm maturity and function. therefore, dysfunctional expression of this gene results in abnormal spermatogenesis. on the other hand, dna damage in spermatozoa is considered to be an important cause of male infertility, and the presence of sperm with dna fragmentation and chromatin abnormalities in human ejaculates is well documented,...

The mean hospital stay was 2.8±1.5 (range, 2-5) days, with a median follow-up of 20 (range, 8-32) months, there was no recurrence. Conclusions: Our homemade single port device is costeffective and more flexible to deal with bilateral renal cysts especially ventral ...
