Objective:Oocyte degeneration has historically been associated with the intracytoplasmic sperm injection(ICSI) technique. We sought to determine whether oocyte degeneration rates were associated with the technician pe...
Objective:To investigate the biochemical relationship between follicular/oocyte maturity and follicular inhibins and activin levels. Design:Prospective study. Setting:Research laboratory in university hospital. Patien...
In patients with polycystic ovary syndrome (PCOS),the proportion of optimal embryos-blastomere number and fragmentation rate-derived from in vitro-matured oocytes after the hCG priming protocol was higher (43.3%) than...
In this study, laser-assisted intracytoplasmic sperm injection (ICSI) improved the fertilization rate and the embryo quality in patients with a history of poor ICSI outcome and with limited metaphase II oocytes. This ...
Objective: The purpose of this study was to compare the effectiveness of a thorough sonographic oocyte retrieval to a routine in vitro fertilization retrieval to induce ovulation, pregnancy, and endocrine changes in p...
Objective: To evaluate androgen levels before and during IVF. To assess for an association between androgen levels and IVF stimulation parameters or IVF pregnancy outcome. Design: Prospective cohort study. Setting: Re...
Objective: This study was conducted to determine whether N-hydroxyethylpiperazine-N-ethanesulfonate (HEPES)-buff-ered medium used for the microinjection of sperm into oocytes may be detrimental for the embryo. Design:...
Y-chromosome microdeletion in male fetuses conceived by intracytoplasmic sperm injection (ICSI) was screened by polymerase chain reaction for sequence-tagged sites in azoospermia factor (AZF)-b and AZFc regions. Treat...
Objective: To report the birth of a baby from the transfer of one embryo after rescue intracytoplasmic sperm injection (ICSI) and preimplantation genetic diagnosis (PGD). Design: Case report. Setting: IVF center. Pati...
Objective: This study determines whether smoking influences ovarian vascularization which thus may impair follicular development. Design: Prospective laboratory study of follicular fluids and granulosa cells from pati...
