Endometriosis Affects Oocyte Morphology in Intracytoplasmic Sperm Injection Cycles?
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 blastocyst formation probability. Endometriosis was also correlated with cycle characteristics. In order to avoid age-related bias, in the first analysis only pa...
متن کاملIntracytoplasmic sperm injection outcome versus intracytoplasmic morphologically selected sperm injection outcome: a meta-analysis.
The development of a modified intracytoplasmic sperm injection (ICSI), called intracytoplasmic morphologically selected sperm injection (IMSI), demonstrated that a profound morphological investigation of the spermatozoon, under the magnification of 6600 x, enables outcome improvement. The aim of this study was to compare ICSI outcome with IMSI outcome. The meta-analysis results demonstrated no ...
متن کاملOocyte morphology does not affect fertilization rate, embryo quality and implantation rate after intracytoplasmic sperm injection.
In this study, we compared the fertilization rate and embryo quality after intracytoplasmic sperm injection (ICSI) as they relate to oocyte morphology. A total of 654 ICSI cycles yielding 5903 metaphase II oocytes were observed. The oocytes retrieved in these cycles were divided into (i) normal oocytes, (ii) oocytes with extracytoplasmic abnormalities (dark zona pellucida and large perivitellin...
متن کاملOptimal Timing for Oocyte Denudation and Intracytoplasmic Sperm Injection
Objectives. To analyze the impact of oocyte denudation and microinjection timings on intracytoplasmic sperm injection (ICSI) outcomes. Study Design. We included ICSI cycles with the following parameters: rank 1 or 2, female age <36 years, male factor infertility, long protocol using GnRH agonist and rFSH for ovarian stimulation, and use of freshly ejaculated sperm (n = 110). Several ICSI parame...
متن کاملPregnancy outcome after intracytoplasmic sperm injection with strontium oocyte activation in a globozoospermic patient.
Dear Editor, I am Dr Xiao-Yu Yang, from the Center of Clinical Reproductive Medicine in the First Affiliated Hospital at the NanJing Medical University, Nanjing, China. We present here a case report of a globozoospermic patient whose partner became pregnant after intracytoplasmic sperm injection (ICSI) with assisted oocyte activation (AOA). Globozoospermia is characterized by the presence of 10...
