Genetic anomalies in infertile Egyptian men and their impact on sperm retrieval rates and intracytoplasmic sperm injection outcome: A retrospective cohort study Open
Background and objectives The current retrospective study aimed to investigate the frequency and types of chromosomal abnormalities among a group of infertile men, as well as their impact on semen parameters, sperm retrieval rates (SRR), a…

Evaluation of seminal plasma levels of vaspin and visfatin in infertile males with elevated sperm DNA fragmentation index: a comparative study Open
Background Sperm DNA fragmentation (SDF) can significantly impact male fertility, especially in cases where there is a substantial level of DNA damage. We aimed in the current study to assess seminal plasma (SP) levels of vaspin and visfat…

Cryopreservation of rare ejaculate and testicular spermatozoa, a novel simple technique; the culture dish slice freezing: A pilot study. Open
Objective: The ability to cryopreserve small numbers of spermatozoa retrieved by testicular sperm extraction (TESE) in males having nonobstructive azoospermia avoids the requirement for repeated surgery and promotes the preservation of fer…

Age related decline of male fertility (ARDMF), the other side of the coin, a review article Open
Background:The effect of male age on male fertility is a debatable subject.Men never stop producing sperms, but there is a decline in sperm quality as a man ages.According to the World Health Organization (WHO) starting around the age of 3…

Examining the effects of a multicomponent oral antioxidant therapy on semen parameters and seminal oxidative stress in males with idiopathic infertility Open
The aim of this study to assess the efficacy of a ten constituent oral antioxidant formula, on various semen parameters and seminal oxidative stress in males with idiopathic infertility. Single center, prospective, comparison the efficacy …
View article: Fresh vs frozen testicular sperm for assisted reproductive technology in patients with non-obstructive azoospermia: A systematic review
Fresh vs frozen testicular sperm for assisted reproductive technology in patients with non-obstructive azoospermia: A systematic review Open
: The use of frozen testicular sperm from men with NOA results in fertilisation and clinical pregnancy rates similar to those of fresh sperm. This may encourage fertility centres to use frozen testicular sperm samples, as this policy has c…
View article: A Global Survey of Reproductive Specialists to Determine the Clinical Utility of Oxidative Stress Testing and Antioxidant Use in Male Infertility
A Global Survey of Reproductive Specialists to Determine the Clinical Utility of Oxidative Stress Testing and Antioxidant Use in Male Infertility Open
This study is the largest online survey performed to date on this topic and demonstrates 1) a worldwide understanding of the importance of this therapeutic option, and 2) a widely prevalent use of antioxidants to treat male infertility. Fi…
View article: Easiness of sperms retrieval in non-obstructive azoospermia is a strong predictor of clinical pregnancy after intracytoplasmic sperm injection
Easiness of sperms retrieval in non-obstructive azoospermia is a strong predictor of clinical pregnancy after intracytoplasmic sperm injection Open
Background: Testicular sperm extraction followed by Intracytoplasmic Sperm Injection (TESE-ICSI) is the only route to genetically father a child in couples with Non-Obstructive Azoospermia (NOA).Objective: The aim was to identify the effec…
