BACKGROUND The availability of an efficient cryopreservation program is especially important in the case of embryos that have undergone blastomere biopsy for PGD. Unfortunately, the freezing/thawing of biopsied embryos has given disappointing results when performed at the cleavage stage. In this study, embryos diagnosed as normal after PGD were grown to the blastocyst stage, frozen and thawed f...

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...

Objective: N-acetyl-cysteine (NAC) has been shown to enhance the action of clomiphene citrate in ovulation induction. The objective of this study was to examine the use of NAC with clomiphene citrate for ovarian stimulation in assisted conception as a model for "Friendly IVF" Design: pilot study Materials and methods: Twenty infertile patients undergoing IVF/ICSI cycles were offered NAC, 1,200 ...

The health economics of IVF and ICSI involve assessments of utilization, cost, cost-effectiveness and ability to pay. In 48 countries, utilization averaged 289 IVF/ICSI cycles per million of population per annum, ranging from two in Kazachstan, to 1657 in Israel. Higher national utilization of IVF/ICSI was associated with higher quality of health services, as indicated by lower infant mortality...

OBJECTIVE To determine if strict morphology correlates with outcome parameters in couples undergoing intracytoplasmic sperm injection (ICSI). DESIGN Retrospective review. SETTING Academic nonprofit IVF center. PATIENT(S) Couples undergoing IVF/ICSI. INTERVENTION(S) In vitro fertilization and ICSI. MAIN OUTCOME MEASURE(S) Samples were evaluated for total sperm count, motlity, progressi...

In assisted reproduction treatments (ART), applying the ICSI method for fertilization of oocytes rather than traditional IVF method, is regarded as controversial two reasons, namely utility and safety. Our study examines an IVF-ICSI Split model couples with unexplained infertility, where male factor meticulously excluded ART conducted by a strict algorithm, commitment to blastocyst culture, alo...

OBJECTIVE To evaluate the association between progesterone elevation on the day of human chorionic gonadotropin (hCG) administration and clinical pregnancy rates of gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles with the transfer of embryos at different developmental stages (day-3 versus day-5 ETs). MATERIAL AND METHO...

Background In vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) are recognized as established and increasingly successful forms of treatment for infertility, yet significant numbers of couples discontinue treatment without achieving a live birth. This study aims to identify major factors that influence the decision to discontinue IVF/ICSI treatments. MaterialsAndMethods We ...

The aim of the present work was to present the outcomes of the patients with Y-chromosome microdeletions treated by intracytoplasmic sperm injection (ICSI), either using fresh (TESE) or frozen-thawed (TESE-C) testicular sperm and ejaculated sperm (EJAC). The originality of this work resides in the comparisons between the different types of Y-microdeletions (AZFa, AZFb, and AZFc) and treatments,...
