BACKGROUND Our aim was to study attitudes towards twins and single embryo transfer (SET) among IVF/ICSI-twin mothers with 3 to 4-year old children. METHODS A national survey was conducted by questionnaire (n = 1769). The study population consisted of IVF/ICSI-twin mothers (n = 266), and the two control groups of IVF/ICSI-singleton mothers (n = 764) and non-IVF/ICSI-twin mothers (n = 739), all...

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...

BACKGROUND To evaluate the safety of cryopreservation in combination with IVF and ICSI, prenatal diagnosis and neonatal outcome were investigated in children conceived from frozen-thawed ICSI embryos (cryo ICSI) and frozen-thawed IVF embryos (cryo IVF). Data were also compared with earlier published results from fresh ICSI and IVF embryos. METHODS Questionnaire data and results of physical ex...

AIM To compare maternal, and neonatal outcomes in IVF/ICSI and spontaneously conceived dichorionic twin pregnancy. METHOD We collected data regarding dichorionic twin pregnancies following in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI, n=162) with the transfer of fresh embryos as well as data regarding spontaneously conceived pregnancies (n=213) delivered after 28 weeks o...

OBJECTIVE To evaluate the outcomes of patients with moderate oligoasthenozoospermia treated with conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). METHODS A total of 99 couples with moderate oligoasthenozoospermia undergoing their first IVF/ICSI cycle were included in the study. Sibling oocytes were randomized to be inseminated either by conventional IVF o...

OBJECTIVE To conduct a meta-analysis of studies assessing the effect of IVF and intracytoplasmic sperm injection (ICSI) on birth defects. DESIGN Meta-analysis. SETTING Centers for reproductive care. PATIENT(S) Patients treated by IVF and/or ICSI. INTERVENTION(S) We identified all studies published by September 2011 with data related to birth defects in children conceived by IVF and/or I...

In pigs, the embryonic developmental ability after intracytoplasmic sperm injection (ICSI) is inferior to that resulting from in vitro fertilization (IVF). We evaluated the timing of cell division up to blastocyst formation on embryonic development after ICSI using either whole sperm (w-ICSI) or the sperm head alone (h-ICSI) and IVF as a control. At 10 h after ICSI or IVF, we selected only zygo...

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 ...

OBJECTIVE This study aimed to compare the clinical outcomes between in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in sibling oocytes. Additionally, we evaluated whether the implementation of split insemination contributed to an increase in the number of ICSI procedures. METHODS A total of 571 cycles in 555 couples undergoing split insemination cycles were included i...

Sperm DNA damage is prevalent among infertile men and is known to influence natural reproduction. However, the impact of sperm DNA damage on assisted reproduction outcomes remains controversial. Here, we conducted a meta-analysis of studies on sperm DNA damage (assessed by SCSA, TUNEL, SCD, or Comet assay) and clinical pregnancy after IVF and/or ICSI treatment from MEDLINE, EMBASE, and PUBMED d...
