Congenital Müllerian anomalies: diagnostic accuracy of three-dimensional ultrasound
1996
Objective To determine whether it is possible to identify and diagnose accurately Mullerian anomalies with three-dimensional (3-D) ultrasound (US). Design Controlled blinded clinical study. Setting Normal human volunteers undergoing infertility evaluation in a university hospital. Patients Forty-two patients who underwent laparoscopy and hysterosalpingography as part of their work up for infertility and were found to have either a normal uterus (30 patients) or a Mullerian abnormality (12 patients) consented to be evaluated with 3-D US by sonographers who were unaware of their infertility history or of their laparoscopy and hysterosalpingography diagnoses. Interventions Transvaginal 3-D US …
Laparoscopic-ultrasonographic combined technique for the creation of a neovagina in Mayer-Rokitansky-Kuster-Hauser syndrome
1996
Objective To create a neovagina using a combined laparoscopic and ultrasonographic technique in Mayer-Rokitansky-Kuster-Hauser syndrome by modification of Vecchietti's operation. Design Case report. Setting Division of Physiopathology of Reproduction, University of Palermo, Palermo, Italy. Main Outcome Measure(s) The advancement of the needle from the pseudohymen, through the vesicorectal space using a triple contrast ultrasonographic technique. Result(s) The ultrasonographic scanning guides the accurate transit from external genitalia to the peritoneal cavity. Conclusion(s) This original approach allowed a safe and rapid creation of a neovagina in a case of Mayer-Rokitansky-Kuster-Hauser s…
Percutaneous treatment of uterine fibroleiomyomas: Analysis of complications and quality of life after embolization
2001
Purpose. To determine the rate complications and the quality of life of patients submitted to uterine artery embolization for the treatment of uterine fibroids. Material and method. Thirty-two women, aged 32-52yrs underwent bilateral embolization of the uterine artery. The patients were affected by menorrhagia (100%) associated with: anaemia in 9 cases, intense menstrual pain in 10 and pressure symptoms in 3. The embolization procedure consisted of selective catheterization of the uterine arteries and injection of embolic particles (PVA). A questionnaire was administered to 27 patients over a period of 4-16 months to evaluate the patients' quality of life after the treatment. Results. The p…
Lack of Hypoxic Response in Uterine Leiomyomas despite Severe Tissue Hypoxia
2008
Abstract Hypoxia is now established as a key factor influencing the pathophysiology of malignant growth. Among other effects, hypoxia modulates the expression of a multitude of genes through the induction of hypoxia-inducible transcription factors. This differential gene expression favors angiogenesis, cell survival, an invasive/metastatic phenotype, and resistance to anticancer therapies. Because benign tumors do not exhibit these traits, one might expect these entities to be neither hypoxic nor to induce the genetic hypoxia response program. To test this hypothesis, an investigation of the oxygenation status of 17 leiomyomas and 1 leiomyosarcoma of the uterus using polarographic needle el…
Hysteroscopic resection of the septum improves the pregnancy rate of women with unexplained infertility: a prospectine controlled trial
2009
Objective: To assess fecundity of infertile women after surgical correction of uterine septum. Design: Prospective controlled trial. Setting: Three academic infertility clinics. Patient(s): Forty-four women affected by septate uterus and otherwise unexplained infertility represented the study group (group A), and 132 women with unexplained infertility were enrolled as control subjects (group B). Intervention(s): Hysteroscopic metroplasty was performed in group A, and group B was managed expectantly. All women were followed-up for 1 year without any other intervention. Main Outcome Measure(s): Fecundity rate was calculated as the number of pregnancies per 100 person-months Result(s): Pregnan…
The transcriptome of spermatozoa used in homologous intrauterine insemination varies considerably between samples that achieve pregnancy and those th…
2009
Objective To differentiate transcripts' expression in the sperm from patients who achieved pregnancy in their first IUI cycle from those who did not. Basic sperm analysis is limited to forecasting pregnancies by means of assisted reproduction. New assays, such as microarray analysis, are potential predictive tools for this purpose. Design Nested case-control study. Setting University-affiliated private setting. Patient(s) Twenty sperm samples were obtained from infertile males undergoing their first IUI cycle with healthy partners. Sperm samples with which pregnancy was achieved (P; n=10) and those with which it was not achieved (NP; n=10) were identified and their respective messenger RNA …
Cigarette smoking affects uterine receptiveness
2006
Background Cigarette smoking has long been known to have an effect on female fertility. The existence of an ovarian factor is clear when one considers that the mean age of the menopause is lower and IVF cycle outcome is worse in heavy smokers. The hypothesis of a concomitant uterine effect is raised by indirect evidence from in vitro and in vivo studies, but as yet, no direct evidence has been gained to confirm its existence. In this work, we analyse the association between smoking habit in oocyte recipients and cycle outcome. Methods We have retrospectively analysed the outcome of all oocyte donation cycles performed in our clinic from January 2002 to June 2005 from which there was availab…
GnRH agonist administration at the time of implantation does not improve pregnancy outcome in intrauterine insemination cycles: a randomized controll…
2009
Objective To assess whether GnRH agonist administration in the luteal phase improves pregnancy outcome in intrauterine insemination (IUI) cycles. Design Single-center, randomized, single-blind, placebo-controlled trial. Setting University-affiliated infertility clinic, between February 2005 and December 2007. Patient(s) Three hundred forty-four women undergoing IUI owing to mild to moderate male factor or donor sperm indication. Intervention(s) Random administration to either a single subcutaneous injection of 0.1 mg triptorelin (group A; n = 172) 8 days after hCG administration, or solvent only (group B; n=172) at the same time. Main Outcome Measure(s) Pregnancy rate was the primary outcom…
Ovarian stimulation does not influence the uterine immune environment in healthy infertile women.
2019
Abstract Research question There is some controversy regarding the impact of ovarian stimulation on immune cells in women undergoing IVF. The study's aim was to determine whether ovarian stimulation affected immune uterine cells in healthy women undergoing IVF. Design This prospective cohort study included 28 patients undergoing IVF and 47 healthy oocyte donors. Endometrial biopsies were taken in a natural cycle and after ovarian stimulation. All participants had a normal karyotype, pelvic ultrasound and cervical cytology results and thyroid-stimulating hormone concentration, as well as normal glucose and insulin concentrations and inherited and acquired thrombophilia test results. Screenin…

2003
Tamoxifen exhibits agonistic properties on the uterus. We describe a premenopausal woman who, while having tamoxifen due to a diagnosis of in situ ductal carcinoma, developed endometriosis requiring surgery.
