Summary: Telomeres are repetitive DNA sequences that protect the ends of eukaryotic chromosomes and play a crucial role in maintaining the integrity and stability of the genome. Shortening of telomeres can occur due to factors such as aging, DNA replication, oxidative stress, and genotoxic agents. However, telomeres can be lengthened by telomerase and alternative lengthening mechanisms. If telomeres become critically short, it can lead to genomic instability and abnormalities in cell division. The effects of assisted reproductive technologies (ARTs), such as ovarian stimulation, culture conditions, and cryopreservation procedures, on telomere length and telomerase activity in oocytes and embryos have been extensively studied. These parameters could potentially serve as biomarkers for assessing the quality of oocytes and embryos in ART centers.

Summary: In 2014, 1.93 million ART cycles were performed in 76 countries, with trends showing increased success rates, frozen embryo transfer cycles, single embryo transfer, and preimplantation genetic testing. Utilization rates and effectiveness of ART continue to improve globally.

Summary: After adjusting for different triggers and egg freeze versus ICSI, it was found that lower total gonadotropin dose and higher gonadotropin dose per day were associated with more immaturity. The type of trigger method used for final maturation was related to immaturity due to trigger assignment based on response. The association between the use of ICSI and less immaturity was attributed to additional maturation time in the ICSI group.

Summary: ICSI has become essential in assisted reproductive technology since the first successful pregnancies were reported. Piezo-ICSI, using a piezo drive unit and a micropipette with a flat tip, has shown higher survival and fertilization rates compared to conventional-ICSI for mouse oocytes. Limited studies on human oocytes also suggest that piezo-ICSI may have higher fertilization rates, aiming to improve clinical results compared to conventional ICSI.

Summary: The report provides data on the utilization, effectiveness, and safety of assisted reproductive technology (ART) globally in 2013, showing an increase in ART cycles and changes in trends such as a rise in the proportion of older women undergoing non-donor ART. Further efforts are needed to improve the quality and consistency of reporting ART data by registries.

Summary: This study aims to assess the correlation between paternal age and clinical pregnancy and live birth rates in egg donation cycles. The results showed that paternal age was negatively correlated with the number of oocytes utilized, normal semen parameters, fertilization, clinical pregnancy, and live birth rates. Therefore, the influence of paternal age on reproductive outcomes should be considered in intracytoplasmic sperm injection donor cycles.

Summary: After more than four decades of assisted reproductive technology (ART) practice, the failure of in vitro fertilization (IVF) treatments and recurrent implantation failures (RIFs) and repeated pregnancy loss (RPL) remain significant issues. This article reviews different therapeutic options and suggests that immunomodulation and predictive biomarkers may be promising solutions.

Summary: We report silk fibroin-based microneedles for transdermal delivery of triptorelin-loaded nanoparticles to improve bioavailability and self-administration of triptorelin. The developed microneedles showed good mechanical properties and increased transdermal release of triptorelin, indicating their potential therapeutic role in assisted reproductive technology regimens.

Summary: This study discusses fertility concerns specific to LGBTQ+ and single-parent-to-be populations and reviews special considerations for evaluating and treating these patients in reproductive medicine. It emphasizes the need for equitable treatment regardless of sexual orientation or partner status and the importance of healthcare providers being comfortable and confident in addressing the needs of these populations.

Summary: In this study, the outcomes of ART in 223 couples with unexplained infertility were analyzed, and the gene expression associated with DNA modification, cell death, immune response, and senescence in infertile women's endometrium and follicular fluid were investigated. The results showed significant differences in women who successfully got pregnant compared to those unable to conceive, depending on age, duration of infertility, number of retrieved oocytes, zygotes, and transferred embryos. Furthermore, gene expression analysis revealed upregulation of genes associated with cell death and immune response in the endometrium of women who successfully got pregnant.

Summary: The study found that assisted reproductive technology (ART) is associated with an increased risk of hospitalization in children, particularly for infectious and allergic diseases. However, when controlling for genetic and environmental confounders, ART is not associated with an increased risk of childhood hospitalization.
