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...

Partial or complete fertilization failure after IVF was reported in 5-10% of cycles. Total fertilization failure in patients with normal sperm parameters is rare but very stressful incident after IVF. To rescue the IVF cycles after total fertilization failure, ICSI of unfertilized oocytes after initial insemination has been reported.We reviewed a 2 years experience of rescue ICSI and analyzed t...

During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of frozen-thawed embryo transfer (FET) from cycles of conventional in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). In the present stu...

IMPORTANCE Intracytoplasmic sperm injection (ICSI) is increasingly used in patients without severe male factor infertility without clear evidence of a benefit over conventional in vitro fertilization (IVF). OBJECTIVE To assess national trends and reproductive outcomes for fresh IVF cycles (embryos transferred without being frozen) following the use of ICSI compared with conventional IVF with ...

BACKGROUND There is considerable uncertainty as to the significance of a high sperm DNA fragmentation index (DFI) for achieving a successful pregnancy. METHODS The sperm DFI of 124 patients undergoing 192 IVF cycles and of 96 patients undergoing 155 ICSI cycles was determined using the sperm chromatin structure assay on neat sperm. RESULTS The rate of continuing pregnancies in ICSI cycles (...

European results of assisted reproductive techniques from treatments initiated during 1999, are presented in this third report. Data were collected mainly from pre-existing national registers. From 22 countries 538 clinics reported 258 460 cycles: IVF 125 370, ICSI 95 221, frozen embryo replacement (FER) 34 002 and oocyte donations (OD) 3867. In eight countries, where all clinics reported to th...

Objective The present study was designed to evaluate the effect of couple`s obesity simultaneously on in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. MaterialsAndMethods This cross-sectional study was performed in Royan institute between January 2013 and January 2014. The recorded data of all patients during this time period were evaluated. The study population was ...

OBJECTIVE The decision to use in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or split insemination (IVF-ICSI) in the first cycle is based on the number of motile sperm. Hence, total fertilization failure (TFF) often occurs during IVF cycles, despite normozoospermia. To investigate whether the cumulative motile swim-up spermatozoa percentage at 22 hours post-insemination ...

Objective: To assess the influence of MII oocyte morphology on the fertilization outcome and embryo development in ART cycles. Since, age may affect the quality of oocyte, the role of women's age was also evaluated following IVF or ICSI cycles. Materials and Methods: 200 MII oocytes from 30 IVF and ICSI cycles were evaluated. The morphology of oocytes that were fertilized in IVF cycles (IVF+) w...

BACKGROUND Sperm quality may degrade during transit through the male reproductive tract in some individuals. In this setting surgically retrieved testicular sperm may outperform ejaculated samples for use with in vitro fertilization (IVF) and intracytoplasmic sperm injection (IVF-ICSI). We sought to describe one center's experience with the use of fresh testicular sperm after prior failed IVF-I...
