Purpose: To analyze whether the thyroid status is affecting in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. Methods: In this retrospective cohort study, we reviewed the medical records of 426 infertile women who underwent IVF/ICSI cycles. Included were hypothyroid (HypoT-LT4) patients with serum thyroidstimulating hormone (TSH) concentrations > 4.0 μIU/mL, which wer...

OBJECTIVE To determine if strict morphology correlates with outcome parameters in couples undergoing intracytoplasmic sperm injection (ICSI). DESIGN Retrospective review. SETTING Academic nonprofit IVF center. PATIENT(S) Couples undergoing IVF/ICSI. INTERVENTION(S) In vitro fertilization and ICSI. MAIN OUTCOME MEASURE(S) Samples were evaluated for total sperm count, motlity, progressi...

OBJECTIVE To evaluate the association between progesterone elevation on the day of human chorionic gonadotropin (hCG) administration and clinical pregnancy rates of gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles with the transfer of embryos at different developmental stages (day-3 versus day-5 ETs). MATERIAL AND METHO...

OBJECTIVE The present study was conducted to evaluate the effect of serum progesterone (P) levels on the day of human chorionic gonadotropin (hCG) administration on embryo quality and pregnancy rate in intracytoplasmic sperm injection (ICSI) cycles. DESIGN AND SETTING This was a retrospective analysis conducted in the in vitro fertilization (IVF) unit of a tertiary hospital. PATIENTS Two hu...

BACKGROUND The sperm chromatin structure assay (SCSA) has been suggested as a predictor of fertility in vivo as well as in vitro. The available data however, have been based on limited numbers of treatments. We aimed to define the clinical role of SCSA in assisted reproduction. METHODS A total of 998 cycles [387 intrauterine insemination (IUI), 388 IVF and 223 ICSI] from 637 couples were incl...

Background: To evaluate the outcomes of using in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI cycle) techniques in hypogonadotropic hypogonadism women and comparing them to women with tubal factor infertility. Materials and Methods: Data from 81 hypogonadotropic hypogonadism (HH) patients treated with IVF/ICSI in the period from early 2009 until the end of 2010 were analyze...

Objective Recently the laparoscopic ovarian drilling (LOD) has been used as a surgical treatment for ovulation in women with polycystic ovarian syndrome (PCOS), although its mechanism and outcomes are still unclear. This study was undertaken to evaluate the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes in clomiphene-resistant women with PCOS who were treated with...

BACKGROUND Several studies have investigated seasonal variations during IVF. Their results are contradictory, especially concerning fertilization and pregnancy rates. The aim of the present study was to re-evaluate these parameters using a large number of IVF cycles. METHODS A total of 7368 IVF cycles conducted in Switzerland between 1995 and 2003 were retrospectively analysed. To avoid a bia...

Embryo transfer policy and luteal supplementation was reviewed, comparing literature data and the results from the Maribor IVF Centre. A retrospective analysis of 1024 cycles in patients undergoing IVF, intracytoplasmic sperm injection (ICSI) or testicular sperm aspiration in unstimulated cycles was carried out using four different approaches for cycle monitoring. This showed that the most succ...

This study aimed to evaluate the impact of a short insemination procedure on embryo development, assess the reliability of a fertilization check prior to the appearance of pronuclei and elucidate the role of rescue intracytoplasmic sperm injection (R-ICSI). Patients who had ≥9 eggs, were aged <38 years and had normal semen samples were included. The sibling eggs of each patient were divided int...
