چکیده
INTRODUCTION Some unexplained infertile couples may have fertilization failure; the in vitro fertilization (IVF) with high insemination concentration (HIC) and intracytoplasmic sperm injection (ICSI) were reported to give better fertilization rate when compared to standard IVF procedure. OBJECTIVE To compare the fertilization rate, abnormal fertilization rate, total fertilization failure rate, and pregnancy rate between the IVF with HIC and ICSI for the treatment of unexplained infertility. MATERIAL AND METHOD The prospective study in 36 unexplained infertile couples in Thammasat University Hospital between 2005-2007 was performed by equally dividing sibling oocytes in assisted reproductive technology cycles with controlled ovarian hyperstimulation protocol in each patients into two groups; group I were inseminated with 200,000 sperms (IVF with HIC) and group II underwent ICSI procedure. The embryos from the better fertilization group were selected to transfer The fertilization rate, the abnormal fertilization rate, the implantation rate, the pregnancy rate and total fertilization failure rate were compared by Chi-square test and Fisher's exact test with statistical significance if p < 0.05. RESULTS The fertilization rate, the abnormal fertilization rate, the implantation rate, the pregnancy rate and total fertilization failure rate of group I and II were 56.97% vs. 70.29% (p = 0.15), 6.56% vs. 1.26% (p = 0.003), 12.50% vs. 15.00% (p = 0.50), 38.46% vs. 36.36% (p = 0.67) and 13.89% vs. 0.0% (p = 0.04) respectively. CONCLUSION ICSI exhibited least total fertilization failure rate (0.0% VS. 13.89%) and gave less abnormal fertilization rate (1.26% vs. 6.56%) with statistical significance in unexplained infertility when compared to the IVF with HIC procedure. Therefore, applying of ICSI procedure may increase the success chance of embryo transfer and pregnancy outcomes.

Comparison between intracytoplasmic sperm injection and in-vitro fertilization (IVF) with high insemination concentration after total fertilization failure in a previous IVF attempt.
The aim of this prospective study was to evaluate whether couples with total fertilization failure in a previous in-vitro fertilization (IVF) attempt should be offered an additional IVF treatment with elevated insemination concentration or should be treated with intracytoplasmic sperm injection (ICSI). In 23 cycles 228 sibling metaphase II (MII) oocytes were randomly divided: 143 and 85 oocytes...

BACKGROUND The aim of this retrospective study is to investigate the relevance of dividing oocytes and using some for traditional in vitro fertilization (IVF) and others for intracytoplasmic sperm injection (ICSI) as of the first IVF cycle in patients with unexplained infertility who have undergone 4 intrauterine insemination (IUI) cycles which produced no pregnancies. METHODS This retrospect...

We report the first 16 cases of a new sperm abnormality which we call 'easily decapitated spermatozoa defect'. This was discovered during intracytoplasmic sperm injection (ICSI) in couples with unexplained infertility. Semen analysis was normal, but minimal micromanipulation for ICSI resulted in decapitation of the spermatozoon during immobilization. For some oocytes the head and tail were inje...
