BACKGROUND/AIMS: Data on the timing of catheter removal technique following embryo transfer (ET) are quite limited. We aimed to compare the reproductive outcomes of intracytoplasmic sperm injection (ICSI)/ET cycles in which the transfer catheter was removed immediately with those in which the catheter was removed after a delay period and hereby to evaluate the impact that the time interval before removal of the catheter following embryo deposit may have on the fertility outcomes. METHODS: A prospective randomized study was designed...

The wide use of assisted reproductive technologies has contributed to the increased risk of ectopic and subsequently heterotopic pregnancy (HP) rate. Cervical ectopic pregnancy is a very rare and life-threatening form of ectopic pregnancy that can also present as HP. We are describing here a case of 34-year-old woman who presented with bleeding heterotopic cervical pregnancy (HCP). The concomitant viable cervical and intrauterine pregnancies were diagnosed at 8 weeks of gestation. Selective fetal reduction was done for cervical pregnancy following which uterine artery embolization was done as a life-saving measure, and subsequently, injection methotrexate was also given...

We evaluated the meiotic and developmental competence of GV-stage equine oocytes vitrified under different conditions. In a preliminary study, using dimethyl sulfoxide (D), ethylene glycol (EG) and sucrose (S) as cryoprotectants, the maturation rate was higher for cumulus-oocyte complexes (COCs) held overnight before vitrification (37%) than for those vitrified immediately (14%; P < 0.05). Thereafter, all COCs were held overnight before vitrification. In Experiment 1 we compared 1 min (1 m) and 4 min (4 m) exposure to vitrification and warming solutions; oocytes that subsequently matured were fertilized by ICSI...

Patients with very low sperm count through direct sperm examination can exhibit extreme oligozoospermia or cryptozoospermia (after centrifugation). The management of these patients is a real challenge for both clinicians and biologists. In this retrospective and comparative cohort study, we compared the andrological phenotype of patients with extreme alterations of spermatogenesis and assessed whether the origin of spermatozoa (testicular or ejaculate) had any influence on intracytoplasmic sperm injection (ICSI) outcomes...

PURPOSE: This study seeks to evaluate the association between follicular fluid (FF) coenzyme Q10 (CoQ10) levels, embryo morphokinetics, and pregnancy rate. METHODS: Sixty infertile patients who underwent intracytoplasmic sperm injection (ICSI) cycles were included in the study. For each patient, CoQ10 level of the follicular fluid was measured by high-performance liquid chromatography system. After the ICSI of each oocyte, the relationship between the level of CoQ10 content of each follicular fluid, the subsequent embryo quality, and embryo morphokinetics was investigated...

In this study the clinical and neo-natal outcomes after transfer of blastocysts derived from oocytes containing aggregates of smooth endoplasmic reticulum (SER) were compared between IVF and intracytoplasmic sperm injection (ICSI) cycles. Clinical and neo-natal outcomes of blastocysts in cycles with at least one SER metaphase II oocyte (SER + MII; SER + cycles) did not significantly differ between the two insemination methods. When SER + MII were cultured to day 5/6, fertilization, embryo cleavage and blastocyst rates were not significantly different between IVF and ICSI cycles...

Pentoxifylline (PF) represents an effective tool in stimulating motility and identifying viable spermatozoa in intracytoplasmic sperm injection (ICSI) patients presenting exclusively with immotile spermatozoa. However, its use is not universally accepted for its possible detrimental effects on oocytes, embryos or newborns. To evaluate whether PF use may affect obstetrical/neo-natal outcomes, 102 patients achieving a clinical pregnancy after a PF-ICSI in four IVF units in Spain and Italy were followed up after delivery...

Cynomolgus macaques are an important primate species for drug metabolism studies; however cynomolgus CYP2C76, an important drug-metabolizing enzyme, accounts for drug metabolism differences to humans, so that CYP2C76-null animals might show drug-metabolizing properties more similar to humans. In this study, attempts were made to produce CYP2C76-null animals by assisted reproduction technology. Oocytes and sperm collected from the heterozygotes for the null allele (c.449TG > A) were subjected to intracytoplasmic sperm injection, and the embryos produced were cultured in vitro through the blastocyst stage...

There are variant rates of oocyte degeneration after intracytoplasmic sperm injection (ICSI) among different patients. Oocyte degeneration after ICSI may reflect the cohort of oocyte quality and subsequent embryo development capacity and clinical outcome. This retrospective study analyzed 255 cycles with at least one degenerated oocyte after ICSI (degeneration group) and 243 cycles with no degenerated oocytes after ICSI (control group). Basic characteristics like female age, body mass index, duration of infertility, hormone (FSH, LH, E2) levels on day 3 of menses, and primary infertility patient rate were similar between the two groups (p > 0...
