THE RELATIONSHIP BETWEEN FOLLICLE SIZE, OOCYTE MATURATION, BLASTOCYST FORMATION, BLASTOCYST PLOIDY, AND PREGNANCY OUTCOMES IN YOUNG WOMEN UNDERGOING IVF.

Unlabelled: The relationship between follicle size, oocyte quality, and blastocyst ploidy is not fully established. This question becomes especially important for poor responders and older reproductive age women, where optimal follicle size and oocyte quantity cannot always be achieved during ovarian stimulation. The aim of this study is to determine the relationship between follicle size, oocyte maturation, blastocyst formation, blastocyst ploidy, and pregnancy outcomes in young women undergoing in vitro fertilization (IVF).

Impact of Shorter Abstinence Periods on Semen Parameters: A Systematic Review and Meta-Analysis.

Purpose: The success of assisted reproductive technology (ART) relies heavily on semen parameters, and it is influenced by the length of the abstinence period. The World Health Organization (WHO) recommends a 2- to 7-day abstinence period. Even so, efficacy is still suboptimal.

Prostate cancer clinical trials in low- and middle-income countries.

Background: Prostate cancer is the second most common form of cancer and a leading cause of cancer-related death in men. In an era of evidence-based medicine, clinical trials play a critical role, and adherence to best practices is crucial in managing complicated and non-communicable diseases, such as prostate cancer. For this reason, extrapolating research conducted in high-income countries (HICs) to low-middle-income countries (LMICs) may lead to incorrect findings or treatment plans for patients in these areas.

Management of Recurrent Implantation Failure and Hereditary Thrombophilia: A Case Report.

Recurrent implantation failure (RIF) is one of the core problems for assisted reproductive technology (ART). High-quality, euploid embryos and synchronization between the embryonic stage and the uterine endometrial lining are crucial for positive outcomes. Molecular biology techniques have significantly transformed assisted reproductive technology (ART).

Live motile sperm sorting device for enhanced sperm-fertilization competency: comparative analysis with density-gradient centrifugation and microfluidic sperm sorting.

Purpose: A live motile sperm sorting device (LensHooke CA0) developed to prevent the deleterious effects of centrifugation was evaluated comparatively with conventional density-gradient centrifugation (DGC) and microfluidic-based device (Zymot) in sperm selection.

Methods: Semen samples from 239 men were collected. CA0 under different incubation intervals (5, 10, 30, and 60 min) and temperatures (20, 25, and 37℃) was conducted.

Novel sperm chromatin dispersion test with artificial intelligence-aided halo evaluation: A comparison study with existing modalities.

Background: Sperm chromatin dispersion test is a common and inexpensive technique to assess sperm DNA fragmentation, but its subjectivity in assessing a small number of spermatozoa is a disadvantage.

Objectives: To study the efficacy of a new sperm chromatin dispersion test kit (R10) combined with an artificial intelligence-aided halo-evaluation platform (X12) and compare the results to those of existing sperm DNA fragmentation testing methods.

Materials And Methods: Semen samples from normozoospermic donors (n = 10) and infertile men with abnormal semen parameters (n = 10) were enrolled.

Bridging the Gap between AZF Microdeletions and Karyotype: Twelve Years' Experience of an Infertility Center.

Purpose: Despite all past efforts, the current guidelines are not explicit enough regarding the indications for performing azoospermia factor (AZF) screening and karyotype, burdening clinicians with the decision to assess whether such tests are meaningful for the infertile male patient. These assessments can be costly and it is up to the healthcare practitioner to decide which are necessary and to weigh the benefits against economic/psychological harm. The aim of this study is to address such gaps and provide update on current management options for this group of patients.

Oxidative Stress and Toxicity in Reproductive Biology and Medicine: A Comprehensive Update on Male Infertility Volume II - Conclusion.

Infertility is a globally under-recognized public health problem significantly impacting individual health and socioeconomics affecting millions of couples. The reasons for infertility are manifold and not only include many couples decision to postpone having children but also diseases (e.g.

Interplay of Oxidants and Antioxidants in Mammalian Embryo Culture System.

One principal purpose of assisted reproductive technology (ART) is to produce viable and good quality embryos. However, a variety of environmental factors may induce epigenetic changes in the embryo. Moreover, laboratory conditions including the culture media may also affect embryo development.

A rare abnormality of ejaculatory duct opening in the bladder trigone in a 33-year-old male associated with primary infertility: Case report and literature review.

Genitourinary anomalies constitute a large proportion of congenital malformations. However seminal tract anomalies, particularly ejaculatory duct (ED) anomalies are very rare and little information exists on the topic. We are reporting a very rare case of bilateral ectopic EDs opening in the bladder trigone in a 33-year-old gentleman presenting for evaluation for primary infertility.

Impact of Varicocele Repair on Semen Parameters in Infertile Men: A Systematic Review and Meta-Analysis.

Purpose: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls.

Temporal decline of sperm concentration: role of endocrine disruptors.

Introduction: Male infertility is a widespread disease with an etiology that is not always clear. A number of studies have reported a decrease in sperm production in the last forty years. Although the reasons are still undefined, the change in environmental conditions and the higher exposure to endocrine-disrupting chemicals (EDCs), namely bisphenol A, phthalates, polychlorinated biphenyls, polybrominated diphenyl esters, dichlorodiphenyl-dichloroethylene, pesticides, and herbicides, organophosphates, and heavy metals, starting from prenatal life may represent a possible factor justifying the temporal decline in sperm count.

ANXA2, SP17, SERPINA5, PRDX2 genes, and sperm DNA fragmentation differentially represented in male partners of infertile couples with normal and abnormal sperm parameters.

This study aims to evaluate the expression of genes associated with the fertilisation potential and embryo development, sperm DNA fragmentation (SDF), and acrosome reaction in male partners of infertile couples with different sperm parameters compared to fertile men. First, male partners of infertile couples with abnormal (N = 25) and normal sperm parameters (N = 25), and fertile men (N = 10) were included in experimental groups I, II, and controls respectively. The mRNA levels of the Annexin A2 (ANXA2), Sperm protein 17 (SP17), Plasma serine protease inhibitor (SERPINA5), and Peroxiredoxin-2 (PRDX2) genes and SDF were evaluated.

Facial atopic dermatitis may be exacerbated by masks: insights from a multicenter, teledermatology, prospective study during COVID-19 pandemic.

Background: Patients with atopic dermatitis (AD) display a defective skin barrier, consequently they may experience inflammatory flares with different exposures, including masks. Actually, beside scattering case reports, no study focused on the possible AD flaring due to masks.

Methods: In this multicenter prospective study AD patients with facial manifestation were followed with teledermatology and evaluated by two board-certified dermatologists at the baseline (T0) and after 1 month (T1) in which patients started to wear masks >6 hours per day.
