The aim of the present case-control study was to develop a noninvasive adjuvant tool for the diagnosis of endometriosis. Serum samples from 100 patients undergoing intracytoplasmic sperm injection were split into two groups according to the…
OBJECTIVE: This 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. METHODS: This case-con…
PURPOSE: The goal for the present study was to implement a technique for protein extraction and identification in human cumulus cells (CCs). METHODS: Forty samples of CCs were collected after ovum pick-up from patients undergoing intracyto…
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 bla…
OBJECTIVE: To 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 inje…
PURPOSE: To investigate the predictive value of the motile sperm organelle morphology examination (MSOME) on embryo morphology. METHODS: The morphologies of 540 embryos obtained from 60 couples undergoing ICSI were evaluated from days 1 to…
PURPOSE: To 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. METHODS: In this descriptive study…
BACKGROUND: The 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 injecti…
PURPOSE: To 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 s…
PURPOSE: To investigate if there is a correlation between the prevalence of sperm with large nuclear vacuoles (LNV) and intracytoplasmic sperm injection (ICSI) outcomes. METHODS: Two hundred male patients undergoing ICSI had their sperm mo…
PURPOSE: To 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. METHODS:…
BACKGROUND: This study compares the developmental capacity of gametes retrieved from the largest follicle with small follicles of a cohort in controlled ovarian stimulated cycles. MATERIALS AND METHODS: This prospective study performed in …
PURPOSE: To 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. METHODS: A total of 71 patients age ≤35 years ol…
PURPOSE: To identify the correlation between different cycles, patient factors and blastocyst characteristics. METHODS: The study included 420 patients undergoing ICSI cycles and 2781 graded blastocysts, which took into account the blastoc…
