BACKGROUND In vitro culture (IVC) and IVF of preimplantation mouse embryos are associated with changes in gene expression. It is however not known whether ICSI has additional effects on the transcriptome of mouse blastocysts. METHODS We compared gene expression and development of mouse blastocysts produced by ICSI and cultured in Whitten's medium (ICSI(WM)) or KSOM medium with amino acids (IC...

Intracytoplasmic sperm injection is more being used for non-male factor indications, although it was developed overcoming infertility of males because pregnancy rate in vitro fertilization still < 40%. This work aims at evaluating the injecting cycle fertilization/ efficiency infertile women and factors that predicting clinical rate. Al-Nahrain University High Institute Infertility Diagnosis...
BACKGROUND Women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) who have a predicted poor ovarian response (POR) present a challenge for reproductive medicine specialists. Traditional Chinese medicine (TCM) is commonly used in China for such patients, in the belief that it will improve the ovarian response and ultimately increase pregnancy rates. However, there ...
BACKGROUND In in vitro fertilization (IVF) and intracytoplasmatic sperm injection (ICSI) treatment a large drop is present between embryo transfer and occurrence of pregnancy. The implantation rate per embryo transferred is only 30%. Studies have shown that minor intrauterine abnormalities can be found in 11-45% of infertile women with a normal transvaginal sonography or hysterosalpingography. ...
background: assisted reproductive technologies (art) are known as a treatment for infertility in which oocyte undergoes manipulation outside body. the aim of this study was to study the evaluation of birth defects in infants conceived through assisted reproductive technologies (art) and compare them with naturally-conceived infants. materials and methods: in this retrospective study, four hundr...
