Optimal Timing for Oocyte Denudation and Intracytoplasmic Sperm Injection

Optimal 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...

Denudation and sperm injection interval timing: impact on outcome of intracytoplasmic sperm injection

BACKGROUND Given the importance of timing of denudation and oocyte injection during assisted reproductive technology cycles, a study was undertaken of the impact of timing on the outcome of intracytoplasmic sperm injection in a cohort of patients from a private in vitro fertilization center. METHODS The study included patients who underwent fresh intracytoplasmic sperm injection-embryo transf...

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...

Intracytoplasmic sperm injection (ICSI).

Intracytoplasmic Sperm Injection

Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique [4] (ART) initially developed by Dr. Gianpiero D. Palermo [5] in 1993 to treat male infertility [6]. It is most commonly used in conjunction with in vitro [7] fertilization [8] (IVF) or a less commonly used technique called zygote intrafallopian transfer [9] (ZIFT). In natural fertilization [8], the sperm [10] must pe...
