Sperm DNA fragmentation (SDF) has emerged as an important biomarker in the assessment of male fertility potential with contradictory results regarding its effect on ICSI. The aim of this study was to evaluate intracytoplasmic sperm injection (ICSI) outcomes in male patients with high SDF using testicular versus ejaculated spermatozoa. This is a prospective(More)
Elevated levels of reactive oxygen species (ROS) are detected in 25% to 80% of infertile men. They are involved in the pathology of male infertility. Understanding the effect of increasing levels of ROS on the differential expression of sperm proteins is important to understand the cellular processes and or/pathways that may be implicated in male(More)
Forty-six XX disorder of sex development is an uncommon medical condition observed at times during the evaluation of a man's fertility. The following is a case series and literature review of phenotypically normal men diagnosed with this karyotype. Our goal is to comprehend the patients' clinical presentation as well as their laboratory results aiming to(More)
The aim of the study was to evaluate the sperm retrieval rate by microsurgical testicular sperm extraction (TESE) in familial idiopathic nonobstructive azoospermia (NOA). One hundred and nineteen patients with idiopathic NOA who underwent microsurgical TESE over the past 5 years were included. Patients were then divided into two groups; Group 'A' with(More)
Objective of this retrospective study was to assess the presence and clinical grade of varicocele among Qatari and non-Qatari men evaluated for infertility. Diagnosis of varicocele was performed clinically and confirmed via colour Doppler ultrasonography. A total of 455 infertile male patients (mean age 36.3 ± 7.6 years) were divided into either Qatari (n =(More)
Varicocele is a well-established cause of male subfertility, which is directly proportional to its clinical grade. Although newer ultrasonic grading systems have taken into account the existence of pampiniform venous plexi, little is known about the clinical significance of the number of veins ligated during surgery. Very few undersized studies reported an(More)
Seminal oxidative stress (OS) is well-known to affect male fertility status. The discrepancy in OS measurement has hindered its clinical use as a quality indicator for semen. Some tests measured single markers of oxidants or reductants, leading to lack of standardization of results. Oxidation-reduction potential (ORP) is a better representative for OS as it(More)
Standard analyses for evaluating semen quality require technical expertise and are interpretive in nature. Oxidative stress (OS) alters many of the semen parameters; thus, a measure of OS could be an indicator of semen quality. Static oxidation-reduction potential (sORP) is a universal measure of OS traditionally used in environmental applications but is(More)
BACKGROUND Premature ejaculation (PE) is a highly prevalent sexual dysfunction among patients with diabetes mellitus (DM). Despite this, the underlying mechanism of this association is poorly understood. In this study, we aimed to investigate the prevalence of PE in a group of patients with DM and explore possible associations linking both conditions(More)
