BACKGROUND The Y chromosome gr/gr microdeletion eliminates two copies of the DAZ gene and several additional transcriptional units and has been associated as a risk factor for infertility. Our objective was to study the presence of the gr/gr deletion in ICSI candidates in our population and to determine whether the laboratory, clinical and ICSI outcome were different in the gr/gr deleted patien...

The impact of intracytoplasmic sperm injection (ICSI) on cryopreserved zygotes and embryos was evaluated by comparing embryo survival and implantation between embryos derived from ICSI and those derived from standard insemination procedures. The study included patients whose excess zygotes and embryos were cryopreserved between September 1993 and December 1994 and who subsequently underwent a f...

The study's objective was to assess the effect of a cognitive behavioral group intervention on the pregnancy rates of patients submitted to in vitro fertilization (IVF) techniques or to intracytoplasmic sperm injection (ICSI). The study was conducted on 188 patients, 93 who participated in a group of psychological intervention before the IVF and ICSI procedures and 95 patients submitted to IVF ...

The purpose of this study was to compare the psychological reactions of men undergoing intracytoplasmic sperm injection (ICSI) (n=18) or in-vitro fertilization (IVF) (n=22). Men monitored their psychological reactions daily for one complete treatment cycle from the first day of down-regulation until the outcome of treatment was known (approximately 52 days). The results showed that ICSI patient...

Four distinct studies were carried out using two data sets of percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic sperm injection (ICSI) procedures performed from March 1993 to January 1997. In study A, an analysis of 181 ICSI treatment cycles following PESA revealed a successful epididymal sperm retrieval rate of 83%. It confirmed that PESA is an effective sperm retrieval meth...

We report the successful outcome of intracytoplasmic sperm injection (ICSI) treatment in two siblings with familial globozoospermia. After controlled ovarian hyperstimulation and oocyte pick-up, retrieved oocytes were mechanically activated before ICSI and a fertilization rate of 33.3% was achieved in the first case. The second couple underwent ICSI without oocyte activation and a 9.1% fertiliz...

OBJECTIVE To assess the neurodevelopmental health of children born after intracytoplasmatic sperm injection (ICSI). DESIGN Prospective controlled blinded study. SETTING Tertiary care center. PATIENT(S) A total of 276 term-born singletons conceived by ICSI and 273 matched spontaneously conceived (SC) singletons at the age of 5.5 years. MAIN OUTCOME MEASURE(S) Neuromotor development asses...
