..Plasma homocysteine levels were significantly reduced by both B vitamins and metformin, but to a greater degree by B vitamins, and higher pregnancy rates were associated with vitamin B treatment...

..To report the responses to IVF surrogacy attempts in a female with a heretofore never described combination of Mayer-Rokitansky-Kuster-Hauser (MRHK) syndrome and triple X karyotype...

..To report the prevalence, presentation, diagnostic modalities, and treatment of ovarian pregnancy in one institution...

..Four widows elected to discard the frozen sperm and all of the remaining spouses were uninterested in its fate. Because none of the samples were requested for use, the need for sperm procurement should be reconsidered...

..To find the type and frequency of chromosomal abnormalities in a selected group of high-order implantation failure (> or =6 IVF trials and > or =15 transferred embryos) and to evaluate its impact on pregnancy outcome...

..The aim of this study was to focus on the pregnancy rate and pregnancy outcome in IVF patients hospitalized for severe or critical OHSS, in one centre, during a period of 6 years...

..Since heritable thrombophilic defects and hyperhomocysteinemia are associated with increased thrombosis, their prevalence was evaluated in RPL patients with special emphasis on combinations of the above pathologies...

..The aim of this study was to evaluate the outcome of ICSI using fresh and cryopreserved-thawed testicular spermatozoa in these patients...

..The aim of this study was to compare the surrogate IVF performance of women with typical and atypical forms including their chances of achieving pregnancy...

..Female factors such as age and ovarian reserve have significant impact upon clinical success rates...

..This may signify that the aetiology of increased MZT after assisted reproduction is the gonadotrophin treatment rather than in-vitro conditions, micromanipulation, or multiple embryo transfer...

..The flexible hMG commencement lowers the cancellation rate to a minimum...

..To assess the efficacy of a protocol involving the discontinuation of the GnRH analogue at the mid-phase of ovarian stimulation for IVF in patients with a previous poor response...

..This case report proves the presence of hyperploid spermatozoa in the seminiferous lumen, and strengthens the necessity of genetic diagnosis of the embryos or fetuses in such pregnancies to fathers with non-mosaic Klinefelter's syndrome...

..Poor sperm morphology is statistically associated with an increase in the incidence of chromosome abnormalities. Our aim was to examine the possible correlation between chromosomal aberrations and sperm morphology in the same cell...

..The presence of this cytokine in somatic as well as in different types of germ cells may suggest its involvement in the regulation of the spermatogenic process and steroidogenesis under physiological and pathological conditions...

..5-63% respectively). A multicentre randomized prospective study would help to confirm the effectiveness of this approach...

..To analyze the results of ongoing pregnancies and deliveries after assisted reproductive technology (ART) in women aged >/=41 years, stratified by year of age...

..To offer surrogacy as a treatment option to patients in whom maternal rather than fetal factors are responsible for high-order unexplained habitual abortions...

..The report includes two cases, one without hormonal replacement, in which preclinical pregnancy occurred, and the second, where P was supplemented immediately upon diagnosis of pregnancy...

..To describe an alternative technique for transvaginal drainage of ascites in a case of severe ovarian hyperstimulation syndrome (OHSS), generalized edema, and obesity...

..CONCLUSIONS: The method described may serve as a simple, non-invasive and reliable assay to help clinicians counsel patients with severe male infertility before referring them for testicular surgery to locate spermatozoa for ICSI...

..The possible association between ovulation-inducing drugs and breast cancer development has been debated. Our aim was to evaluate the incidence of breast cancer in a cohort of women exposed to in vitro fertilization (IVF)...

..It is unclear whether or not testicular sperm extraction (TESE) should be repeated for patients in whom no sperm were found during their first TESE attempt...

....

..A possibly increased rate of early spontaneous abortion in the high-response group warrants further verification...

..To examine whether the addition of one dose of preovulatory GnRH agonist could improve implantation and pregnancy rates in GnRH antagonist IVF cycles...

..We aimed to examine the efficacy of using an embryo transfer medium enriched with hyaluronan (HA) to improve implantation in a selected group of patients aged <43 years with repeated (>4) implantation failures after IVF-embryo transfer...

..We examined the relationship between plasma homocysteine and insulin resistance in patients with polycystic ovary syndrome (PCOS)...

..In conclusion, similar characteristics and dynamics of luteal phase oestradiol and progesterone were demonstrated comparing ovarian stimulation for IVF using GnRH agonist or antagonists, under similar luteal support...

..Several legal and ethical concerns are discussed...

..To find whether the percentage of mature oocytes can be increased in the following ICSI cycle, in a selected group of patients with >or=47% immature oocytes, with the prolongation of hCG-to-oocyte retrieval interval...

..To report a rare clinical case of recurrent heterotopic pregnancy in the same patient following bilateral salpingectomy and in-vitro fertilization (IVF) treatments...

..Therefore, these pregnancies should be considered as high-risk pregnancies, and followed/treated as such. As prevention is the best 'treatment' for OHSS, this may imply the need for more patient-friendly or mild stimulation protocols...

..In patients who conceived after more than three IVF cycles, an additional 'oocyte factor' might be present...

..Culdocentesis for diagnostic purposes has become an unnecessary procedure. Laparoscopic wedge resection was the treatment of choice. The relationship between IUD use and ovarian pregnancies was still strong...
