ObjectiveIt has been observed that faster developmental kinetics are linked with a higher number of embryo cells, improved blastocyst development, and increased rates of implantation and pregnancy. However, the embryonic morphokinetics' pre…

ObjectiveTo identify potential microRNA (miRNA) biomarkers of poor, normal and hyperresponse to controlled ovarian stimulation (COS).MethodsIn the present study, we assessed 40 serum samples from patients undergoing COS. We used ten samples…

ObjectiveTo study which factors affect perinatal outcomes in intracytoplasmic sperm injection (ICSI) cycles.MethodsData was obtained from 402 live births born to 307 patients undergoing ICSI cycles in a private university-affiliated IVF cen…

ObjectiveThis study aimed to look into the use of serum metabolites as potential biomarkers of response to controlled ovarian stimulation (COS) in patients undergoing intracytoplasmic sperm injection (ICSI) cycles.MethodsThis case-control s…

ObjectiveThis study aimed to identify a possible correlation between serum levels of anti-Müllerian hormone (AMH) and oocyte quality, embryo developmental competence, and implantation potential.Methods4488 oocytes obtained from 408 patients…

OBJECTIVE: To identify associations between presence of endometriosis and oocyte defects, embryo developmental potential, and cycle outcomes. METHODS: This study looked into the impact of endometriosis on oocyte and embryo quality, and blas…

ObjectiveTo evaluate a comfortable short protocol with GnRH agonist (GnRHa) in alternate days, with a step down method of gonadotropins administration associated with hCG microdose for young patients undergoing intracytoplasmic sperm inject…

PurposeTo investigate the predictive value of the motile sperm organelle morphology examination (MSOME) on embryo morphology.MethodsThe morphologies of 540 embryos obtained from 60 couples undergoing ICSI were evaluated from days 1 to 5 of …

PurposeTo determine whether Brazilian egg donation treatment outcomes with oocytes donated from infertile couples are equivalent to those obtained worldwide with oocytes donated from fertile egg-donors.MethodsIn this descriptive study, egg-…

BackgroundThe objective of this retrospective cohort study was to evaluate whether the length of pituitary blockage with gonadotrophin-releasing hormone (GnRH) antagonists or the stimulation period influence intracytoplasmic sperm injection…

PurposeTo evaluate: (i) the influence of morphology at cleavage stage on blastocyst formation and implantation, and (ii) whether the transfer of low-quality embryos on day-three would be a better approach than the transfer at blastocyst sta…

PurposeTo investigate if there is a correlation between the prevalence of sperm with large nuclear vacuoles (LNV) and intracytoplasmic sperm injection (ICSI) outcomes.MethodsTwo hundred male patients undergoing ICSI had their sperm morpholo…

PurposeTo compare the results of intracytoplasmic morphologically selected sperm injection (IMSI) between cycles in which the swim-up (SUP) or the density gradient centrifugation (DGC) techniques were used for sperm preparation.MethodsWe ev…

PurposeTo evaluate if several genetic loci that are associated with variation in normal menopause age and early menopause can account for a poor response to controlled ovarian stimulation.MethodsA total of 71 patients age ≤35 years old who …

PurposeTo identify the correlation between different cycles, patient factors and blastocyst characteristics.MethodsThe study included 420 patients undergoing ICSI cycles and 2781 graded blastocysts, which took into account the blastocyst qu…

IntroductionOvarian stimulation is employed in assisted reproduction techniques in order to obtain as many oocytes as possible. The early rise in oestradiol levels may lead to the premature end of the respective cycle. In order to avoid suc…
