OBJECTIVE To investigate the oocyte quality in patients with severe ovarian hyperstimulation syndrome (OHSS). DESIGN Self-controlled clinical study. SETTING University teaching hospital. PATIENT(S) Twenty-two patients from our assisted reproductive technology (ART) program who developed severe OHSS during their first controlled ovarian hyperstimulation for IVF or intracytoplasmic sperm in...

BACKGROUND The aim of this study was to assess the use of testicular sperm for ICSI in azoospermic men with hypogonadotrophic hypogonadism unresponsive to gonadotrophin therapy. METHODS Fifteen patients with hypogonadotrophic hypogonadism who remained azoospermic after hormonal treatment underwent testicular sperm extraction (TESE) and ICSI. These men were recruited from the Egyptian IVF cent...

The latest micromanipulative technique, intracytoplasmic sperm injection (ICSI), has been very successful in cases of severe male factor infertility. The main objective of this study is to report the results of our fIrst experience with ICSI in cases of male factor infertility, as well as patients who had failed their previous cycles with conventional in vitro fertilization (IVF). Normal ...

The aim of this prospective randomized study was to determine if the use of intracytoplasmic morphologically selected sperm injection (IMSI) is associated with gender incidence. Couples who underwent IVF-preimplantation genetic screening (PGS) cycles, as a result of advanced maternal age, were randomly allocated into two groups: intracytoplasmic sperm injection (ICSI; n=80) or intracytoplasmic ...

OBJECTIVE The number of assisted reproductive technology (ART) clinics, ART cycles, clinical pregnancy rate (CPR), and number of newborns conceived using ART have steadily increased in South Korea. This aim of this study was to describe the status of ART in South Korea between January 1 and December 31, 2011. METHODS A localized online survey was created and sent to all available ART centers ...

OBJECTIVE To determine the relationship between sperm chromatin structure assay (SCSA) parameters (DNA fragmentation index [DFI] and high DNA stainability [HDS]), and conventional IVF and IVF/intracytoplasmic sperm injection (ICSI) outcomes. DESIGN Retrospective review and prospective study. SETTING Private IVF clinic. PATIENT(S) Two hundred forty-nine couples undergoing first IVF and/or ...

OBJECTIVE To investigate whether or not body mass index (BMI) is associated with oocyte dysmorphisms. STUDY DESIGN This retrospective study enrolled 1105 patients undergoing intracytoplasmic sperm injection (ICSI). The correlation between BMI and the response to controlled ovarian stimulation (COS) and ICSI outcomes was analysed. Oocyte morphology was determined in metaphase II (MII) oocytes ...

Many protocols have been proposed to improve IVF outcomes for poor ovarian responders. The aim of this study was to explore the relationship between age, ovarian hyperstimulation protocol and IVF/ICSI outcomes in poor ovarian responder (POR) according to the Bologna criteria, and to compare the efficacy of different protocols used in PORs undergoing IVF/ICSI. We retrospectively analyzed clinica...

OBJECTIVE To examine the outcome of assisted reproduction techniques (ART) using cryopreserved semen from patients with cancer. DESIGN Prospective. SETTING Therapeutic semen banking program at a tertiary healthcare center. PATIENT(S) Twenty-nine men with cancer who cryopreserved their sperm before treatment at our facility from 1982 to 2001 and withdrew their samples for assisted reproduc...

PURPOSE The intracytoplasmic sperm injection (ICSI) outcome is depended mainly on oocyte quality. Cytokines and their receptors play a critical role in oocyte maturation, fertilization, and embryo implantation. The purpose of the study was to study the levels of vascular endothelial growth factors (VEGFA, VEGFR1, VEGFA) in follicular fluids (FF) women participating in ICSI-in vitro fertilizatio...
