Objective: To investigate the effect of sperm DNA fragmentation index (DFI) on the clinical outcomes of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods: Infertile couples were prospectively recruited in the Reproductive Center in Jiaozuo Maternal and Child Care Service Centre in Henan, China, from July 2015 to December 2016. All the recruited 228 infertile coup...
BACKGROUND Conventional IVF and ICSI are two common techniques to achieve fertilization. IVF has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. The use of ICSI has been expanded in severe male factor and fertilization failure after IVF cycle. In spite of the widespread use of ICSI in patients with non-male factor infertility, t...
Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and f...
BACKGROUND Failed fertilization after IVF occurs in 10-20% of cycles. Conflicting results of rescue fertilization by ICSI have been reported. We therefore compared the success rate in terms of fertilization and pregnancy of cycles in which rescue ICSI was performed with those from a matched control group of primarily ICSI cycles. METHODS Unfertilized oocytes from IVF cycles with total fertili...
To our knowledge, this is the first analysis in which male and female weights have been combined. The registry dataset covering a 12-year period was analysed for all treatment cycles where an embryo transfer was reported. In all, 706,360 cycles were analysed. Treatments include IVF, ICSI, IVF/ICSI and CPE. The highest success rate in IVF cycles was found in couples, with an obese male partner. ...
STUDY QUESTION During controlled ovarian stimulation (COS), does the duration of premature serum progesterone (P) elevation before administration of hCG affect the outcomes of IVF/ICSI embryo transfer (-ET) cycles? SUMMARY ANSWER The duration of the premature serum P elevation is inversely related to the clinical pregnancy rate of IVF/ICSI-ET cycles. WHAT IS KNOWN AND WHAT THIS PAPER ADDS T...
Short incubation time prevents deleterious effects of cumulus cell degeneration and excess spermatozoa in IVF embryos. We performed a short incubation (3 h) protocol in 328 IVF cycles, in order to compare the developmental potential of regular IVF embryos with those originating from 316 cycles entered our intracytoplasmic sperm injection (ICSI) programme over the same period. Embryo transfers w...
BACKGROUND There is concern that IVF and/or ICSI might have an adverse effect on embryonic development via epigenetic alterations. Such alterations might also be involved in the sex-related growth differences in preimplantation embryos found in some animal species. In the present study we analysed cell numbers of human male and female surplus embryos that developed to the blastocyst stage after...
routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...
OBJECTIVE To determine the relationship between sperm chromatin structure assay (SCSA) parameters (DNA fragmentation index [DFI] and high DNA stainability [HDS]), and conventional IVF and IVF/intracytoplasmic sperm injection (ICSI) outcomes. DESIGN Retrospective review and prospective study. SETTING Private IVF clinic. PATIENT(S) Two hundred forty-nine couples undergoing first IVF and/or ...
