Background: Adenomyosis can lead to infertility and failure of in vitro fertilization. Limited evidence suggests that the use of long-term treatment with gonadotropin-releasing hormone (GnRH) agonists followed by frozen-thawed embryo transfer (FET) may be the preferred approach for women with adenomyosis.

Objective: The aim of this randomized controlled trial is to compare the efficacy of an ultra-long GnRH agonist with standard downregulation in women with adenomyosis undergoing FET.

Article Synopsis
  • - The study investigates how pro-inflammatory diets (PD), indicated by the dietary inflammatory index (DII), affect the gut microbiome, suggesting that higher DII scores correlate with negative gut health outcomes.
  • - A systematic review analyzed ten studies, revealing that a significant number reported weak to moderate links between DII scores and gut microbiome diversity, with anti-inflammatory diets showing a beneficial microbiome profile.
  • - The findings indicate that lower DII scores may lead to a healthier gut microbiome composition, highlighting the need for further research to confirm these associations and explore the implications for dietary recommendations.

The respiratory system was primarily considered the only organ affected by Coronavirus disease 2019 (COVID-19). As the pandemic continues, there is an increasing concern from the scientific community about the future effects of the virus on male and female reproductive organs, infertility, and, most significantly, its impact on the future generation. The general presumption is that if the primary clinical symptoms of COVID-19 are not controlled, we will face several challenges, including compromised infertility, infection-exposed cryopreserved germ cells or embryos, and health complications in future generations, likely connected to the COVID-19 infections of parents and ancestors.

Cancer stem cells (CSCs) are subpopulation of cells which have been demonstrated in a variety of cancer models and involved in cancer initiation, progression, and development. Indeed, CSCs which seem to form a small percentage of tumor cells, display resembling characteristics to natural stem cells such as self-renewal, survival, differentiation, proliferation, and quiescence. Moreover, they have some characteristics that eventually can demonstrate the heterogeneity of cancer cells and tumor progression.

To overcome COVID-19 long-term consequences, one possible approach is to control inflammasomes activation, because SARS-CoV-2 can induce humoral and cellular immune responses. In this opinion article we hypothesized that if it is proven with convincing and unmistakable evidence that firstly, SARS-CoV-2 can enter cells and damage them through its common receptors in the reproductive tissues, and secondly, inflammasome pathway activation is responsible for the damages caused, then the inflammasome inhibitors might be considered as suitable candidates in preventing the pathological effects on the germ cells and reproductive tissues and subsequent fertility.

Objective: Sperm DNA fragmentation and maturation directly interferes with reproductive efficiency. Although there are several methods for assessing sperm DNA integrity, however, many of them are laborious and require high-precision equipment in the clinics. Thus, evaluating economic and reliable methods to prepare suitable sperm for assisted reproductive technologies without DNA damage is critical.

Introduction: Absolute head teratospermia (100% abnormal head morphology) is associated with poor fertility and assisted reproductive techniques results. We aimed to find if it is possible to bypass this disorder using sperm retrieved by testis biopsy.

Methods: Multiple testis biopsies were performed in patients with infertility and absolute head teratospermia who were not able to provide semen on the injection day from 2006 to 2018.

Article Synopsis
  • The study investigates the role of HSPA2 and ADAM2 as biomarkers for selecting the best sperm in ART, focusing on male factor infertility.
  • Researchers compared sperm characteristics and biomarkers in samples from 72 asthenoteratozoospermic (defective sperm) and 42 normospermic (normal sperm) men, finding significant reductions in HSPA2 and ADAM2 in the former group.
  • HSPA2 emerged as a more reliable biomarker for sperm selection compared to ADAM2 or their combination, showing strong correlations with sperm quality, chromatin damage, and embryo quality.

Article Synopsis
  • * It classified 151 semen samples based on their ROS levels into four groups, assessing various semen parameters including antioxidant capacity and sperm DNA integrity.
  • * Results indicated that high ROS levels negatively impacted sperm motility and concentration, while altering methylation status and metabolic profiles significantly.

Kelch-like ECH-associated protein 1 (keap1)-nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway is one of the master regulators of cellular defence against oxidative stress. Epigenetic alterations like hypermethylation of keap1 gene impair keap1-Nrf2 system in several oxidative stress-associated diseases. The objective of this study was to evaluate the epigenetic status of keap1 in sperm DNA of normozoospermic subjects, having different levels of reactive oxygen species (ROS) in seminal plasma.

Background: Sperm processing methods separate motile sperms with good morphology from dead and abnormal forms of sperms, immature germ cells, and non-sperm cells.

Objective: The propose of this study was to compare the efficacy of upstream and swim-up processing techniques to separate sperms with the high quality especially in relation to sperm chromatin integrity.

Materials And Methods: This experimental study used semen samples from 60 normozoospermic men.

Recent evidence indicates a rising trend in premarital sexual activity among young people in Iran. However, little is known about the extent to which young people's sexual behaviours expose them to HIV and STI risks. This study aimed to assess HIV/STI-related sexual risk-taking behaviours (correlates and determinants) and HIV/STI risk perception among male university students in Tehran.

Since the 19th century the Iranian state has been concerned with the size of its population, and policies directed to its increase or decrease have been closely involved with the purpose of nation building. None of these policies have been particularly successful, except for the effective family planning campaign of the 1980s that led to a remarkable drop in population growth, which currently stands at 1.3 per annum, below the replacement level.

The aim of this study was to investigate the efficacy and safety of ondansetron as an augmentative agent to fluvoxamine in the treatment of patients with obsessive-compulsive disorder (OCD). Forty-six men and women, aged 18-60 years, who fulfilled the diagnostic criteria of OCD on the basis of the DSM-IV-TR and had a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score of at least 21 were recruited into the study. The patients randomly received either ondansetron (8 mg/day) or placebo for 8 weeks.

Purpose: Recently discovered Anabaena variabilis phenylalanine ammonia lyase (AvPAL) proved to be a good candidate for enzyme replacement therapy of phenylketonuria. Outstanding stability properties of a mutant version of this enzyme, produced already in our laboratory, have led us to the idea of culture conditions optimization for soluble expression of this therapeutically valuable enzyme in E. coli.

Universal vaccination of neonates and children against diphtheria, tetanus and pertussis has had a tremendous impact on the control of these infectious diseases worldwide. Immunization by the triple diphtheria, tetanus and whole cell pertussis vaccine (DTwP) has been applied in Iran for almost 50 years. Periodic assessment of immunogenicity of this vaccine is an important aspect of successful mass vaccination programs.
