Article Synopsis
- The study aimed to assess how the SARS-CoV-2 pandemic affected assisted reproductive technology practices at centers in Latin America during 2020.
- An online survey was conducted among fertility clinics from July to December 2020, revealing that most centers paused operations early in the pandemic, with the highest response rate from Brazil.
- By December, almost all centers had reopened and resumed treatments, but the number of ART cycles performed remained significantly lower than pre-pandemic levels.
Article Synopsis
- The study examined the utilization, effectiveness, and safety of assisted reproductive technology (ART) in Latin America in 2019, analyzing data from 196 institutions across 15 countries.
- A total of 106,918 ART cycles were initiated, resulting in 18,133 deliveries and highlighting trends such as women over 40 accounting for a significant portion of cycles and varied success rates based on embryo transfer types.
- The findings indicate a rise in ART usage linked to supportive regulations, with a recommendation for single-blastocyst transfers to optimize outcomes and minimize risks associated with multiple births.
Article Synopsis
- - The study analyzed the use and outcomes of assisted reproductive technology (ART) in Latin America in 2019, involving data from 196 institutions across 15 countries, with a total of 106,918 cycles initiated.
- - Key findings included that women aged 40 and above accounted for 32.9% of cycles, with single-embryo transfer (SET) rates demonstrating varying success: 19.5% for fresh transfers and up to 28.1% for frozen-thawed transfers.
- - The research concluded that there is a gradual increase in ART utilization in regions with supportive regulations, emphasizing the importance of single-embryo transfer to minimize risks associated with multiple births, such as increased per
Article Synopsis
- The study analyzed trends in patient characteristics and outcomes of assisted reproductive technology (ART) in Latin America from 1990 to 2018, focusing on effectiveness and safety.
- Over the three decades, there was a shift in the age of women undergoing ART, with a rising percentage of older women and an increase in single embryo transfers (SET), leading to higher delivery rates and fewer high-order multiples.
- The findings underscore the success of the Latin American Registry of Assisted Reproduction (RLA) in promoting regional cooperation and technological advancement in the field of reproductive health.
Article Synopsis
- The research investigates trends in patient characteristics, effectiveness, and safety of assisted reproductive technology (ART) in Latin America from 1990 to 2018, highlighting significant changes over three decades.
- Data analyzed includes 955,117 ART cycles resulting in 191,191 deliveries and 238,045 live births, showing a shift in patient age demographics and the increasing use of single embryo transfer (SET).
- The study concludes that the Latin American Registry of Assisted Reproduction (RLA) has facilitated efficient reporting and technological advancement in ART, leading to improved safety and success rates in the region.
Objective: To introduce a new double-lumen intracervical cannula designed to allow a single-step hysteroscopic myomectomy with nonfragmented complete fibroid extraction after cold enucleation of submucosal type 2 fibroids, avoiding complications related to the use of energy and hypo-osmolar solutions.
Design: Video article depicting the use of a new double-lumen intracervical cannula for single-step hysteroscopic cold myomectomy, according to our institutional care guidelines and after obtaining the patient's informed consent. (The publication of this video has been authorized by the Institutional Ethics Committee of CES University in Medellín, Colombia.
Article Synopsis
- The study examined the use, effectiveness, and safety of assisted reproductive techniques (ART) across 188 institutions in 15 Latin American countries during 2017, collecting data from almost 94,000 treatment cycles.
- Of the initiated ART cycles, there were around 17,000 deliveries resulting in over 20,000 babies, with various delivery rates for different embryo transfer methods, notably single and double embryo transfers showing varying success rates.
- The findings highlight a trend toward increased use of frozen embryo transfers and single embryo transfers, particularly stressing the importance of elective single transfers to reduce risks, especially for younger women and those with multiple blastocysts available.
Article Synopsis
- The study investigates the use, effectiveness, and safety of assisted reproductive technologies (ART) in 15 Latin American countries during 2017, based on data from 188 institutions.
- Results showed 93,600 ART cycles led to 16,976 deliveries and 20,404 births, with notable statistics including a 19.9% delivery rate for ICSI and a 20.2% rate for IVF, especially among women aged 40 and over.
- The research recommends elective single embryo transfer (SET) as the preferred practice when multiple blastocysts are available, to reduce risks associated with multiple births, such as higher perinatal mortality and preterm delivery rates.
Effects of meiotic stage and cumulus status on development of equine oocytes after vitrification was evaluated. Immature oocytes with corona radiata (IMM); in vitro-matured oocytes with corona radiata (MAT CR+); and in vitro-matured oocytes denuded of cumulus (MAT CR-) were vitrified using the Cryotech® method. Warming medium was equilibrated either in 5% CO or Air.

Design: Retrospective cohort study.
Setting: A fertility and IVF center.
