OBJECTIVE To survey the level of disclosure of conception method within families of children conceived by conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) and to examine the factors that might influence parental attitudes and plans for disclosure. DESIGN In-depth questionnaire. SETTING Participants recruited through fertility clinics in the United Kingdom...

Background: C-reactive protein (CRP) can be increased after hormonal stimulations. The changes of CRP might affect the success of in-vitro fertilization (IVF). Objective: The aim of this study was to determine the possible relationship between the serum CRP level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing IVF or intra cytoplasmic sperm injection (IC...

PURPOSE This study was conducted to determine the frequency and contribution of chromosomal abnormalities in miscarriages and in couples with recurrent in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) failure. MATERIALS AND METHODS A total of 221 individuals; 79 with three or more recurrent spontaneous abortions and 142 with at least three IVF/ICSI failures. Chromosomal ana...

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...

Cytokines are key modulators of the immune system and play an important role in the ovarian cycle. IL-18 levels in serum and follicular fluid were analyzed in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. The cohort study group consisted of 90 women, who were undergoing IVF or ICSI. The body mass index (BMI) was determined in all patients; I...

OBJECTIVE It has previously been suggested that embryos developing from intracytoplasmic sperm-injected (ICSI) zygotes with three pronuclei (3PN) are endowed with a mechanism for self-correction of triploidy to diploidy. 3PN are also observed in zygotes after conventional in vitro fertilization (IVF). The parental origin, however, differs between the two fertilization methods. Whereas the vast ...

Background The aim of this study was to compare prenatal outcome of intra cytoplasmic sperm injection (ICSI) pregnancies with pregnancies obtained through in vitro fertilization (IVF). MaterialsAndMethods Retrospectively 532 pregnancies of ART cycles were assessed during 1999-2000. The main outcome measured including abortions, ectopic pregnancies, prematurity, low birth weight, cesarean sectio...

BACKGROUND ICSI is used increasingly often compared with standard IVF. The aim of the present study was to analyse the changes in the use of ICSI, and discuss possible causes and consequences. METHODS Data from National and Regional registers were analysed for trends in the use of ICSI and indications for assisted reproductive technology (ART). RESULTS The use of ICSI increased from 39.6% o...
