Assisted Reproductive Technologies in Latin America and Europe: a Comparative Analysis of Reported Databases for 2013

Conclusion Both regions have points to improve in the quality of their reports. Latin America has produced a more uniform reporting, their clinical results are generallyResumo Objetivo Comparar os registros das t écnicas de reprodução assistida da América Latina e da Europa em relação à qualidade dos dados e acesso, utilização do tratamento, efetividade, segurança e qualidade dos serviços. Métodos Estudo ecológico usando os dados das publicações científicas dos registros da América Latina e da Europa com os ciclos iniciados durante o ano de 2013 (que são os dadosmais recentes disponíveis até dezembro de 2017). Os dados são apresentados como porcentagens, valores mínimos e máximos e números absolutos. Resultados Em comum, vemos que o número de clínicas e de ciclos de tratam ento varia bastante entre os países dentro de cada região emambos os registros, embora o acesso às técnicas de reprodução assistida seja 15 vezes maior na Europa. Na América Latina, os serviços reportam voluntariamente os ciclos iniciados até o cancelamento, o nascimento ou aborto, enquanto que na Europa o que é reportado varia entre os países. Isso faz o registro da América Latina mais uniforme, apesar de ser menos representativo quando comparad...

This study aimed to evaluate the effects of a mild starting dosage of r-FSH ovarian stimulation after the modified prolonged GnRH-a down-regulation protocol for COH on the clinical outcomes in normal ovarian responders undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET). Material and methods: In the retrospective study, the patients were separated into two groups according to the starting dosage of r-FSH: a mild dosage group (75 IU ≤ r-FSH

This study is based on data from a previously published randomized controlled trial conducted from 2014 to 2016.Patients: A total of 322 participants were enrolled.Setting: Private IVF center. Intervention(s): GnRH-antagonist-based IVF cycles triggered with GnRH-a. For the purpose of the study, patients were stratified according to preovulatory LH quartiles (Q1-Q4). Main Outcome Measure(s): Ongoing pregnancy rates (OP), live birth rates (LB) and early pregnancy loss (EPL) rates.Results: The results of the present study showed increasing OP as well as LB rates and decreasing EPL rates with increasing pre-trigger serum LH levels (P for trend

CONCLUSIONS: This review evaluated different temperatures for embryo culture during IVF. There is a lack of evidence for the majority of outcomes in this review. Based on very low-quality evidence, we are uncertain if incubating at a lower temperature than 37°C improves pregnancy outcomes. More RCTs are needed for comparing different temperatures of embryo culture which require reporting of clinical outcomes as live birth, miscarriage, clinical pregnancy and adverse events.

ConclusionArtificial oocyte activation with ionomycin does not adversely affect pregnancy and neonatal outcomes in patients undergoing frozen –thawed embryo transfer, which is beneficial to clinicians counseling patients on the risks of artificial oocyte activation.

ConclusionsA trend towards consistently better results was achieved by removing spermatozoa with fragmented DNA. The fragmentation of the DNA in sperm is the end stage of apoptosis. Sorting of spermatozoa may be improved by selecting parameters of processes active more upstream of apoptosis, such as chromatin decondensation.Trial registrationNCT02166567. June 14, 2014.

CONCLUSIONS: The evidence suggests that sperm selected by hyaluronic acid binding may have little or no effect on live birth or clinical pregnancy but may reduce miscarriage. We are uncertain of the effect of Zeta sperm selection on live birth, clinical pregnancy, and miscarriage due principally to the very low quality of the evidence for this intervention. We are uncertain of the effect of the other selection techniques on live birth, miscarriage, or pregnancy.Further high-quality studies, including the awaited data from the identified ongoing studies, are required to evaluate whether any of these advanced sperm selection...
