Active clinical trials for "Infertility"

To evaluate if ovarian reserve (measured by means of anti-mullerian hormone -AMH- and antral follicle count -AFC-) can predict pregnancy in donor insemination cycles (dIUI) performed in non-infertile women.

Introduction: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic phenomenon, poorly understood and difficult to predict, complicating intense ovarian stimulation cycle. The most severe symptoms, which associate vascular permeability disorders and hypercoagulability, occur in 0.2 to 1% of the cases and often require intensive care. Activation of endothelial, platelet, erythrocyte or leukocyte cells trigger the release of small specific vesicles, called microparticles, used as markers. Classically leading to endothelial dysfunction and hypercoagulability, the endothelial activation phenomenon could constitute the main cause of OHSS or help predict its severity, as established for various other diseases (cerebral stroke, infarct and lupus…). However, so far, this endothelial activation role has never been studied. Objectives: Evaluate the serum level of microparticles as a predictor of adverse outcomes; correlate it to hypercoagulability and changes of endothelial permeability associated with this syndrome. Methodology: Prospective Pilote Cohort study, evaluating before and throughout the ovarian stimulation cycle (6 samples/patient), the serum modulation of: Endothelial activation markers (endothelial-derived microparticles, E-selectin) Procoagulant markers (microparticles from platelet, erythrocyte or leukocyte origin, Von Willbrand factor, thrombin-antithrombin complex, prothrombin fragment 1+2) Endothelial disjunction marker (soluble CD 146) A group of 50 patients will be assessed Techniques: Flow cytometry for measurement of microparticles expressing non specific (Annexin V) and cell specific surface determinants (CD 31, CD 41, CD 45 or glycophorin A). Use of commercial kits for other serum markers.

To assess the impact of the female genital microbiome on ART outcome.

This case-control study compares IVF results and live birth rates in women undergoing IVF with a history of bariatric surgery as compared to 2 age-matched control groups composed of (A) non-operated women matched on cases' post-operative BMI (controls 1) and (B) non-operated severely obese women (controls 2).

The study is a follow up of NCT01844362. Uterus transplantation will be performed from live donors to patients with uterine factor infertility. If will be performed before transplantation. Organ procurement from the donor will be performed by robotic assisted laparoscopy. Transplantation will be by laparotomy. Embryo transfer will be done 10-12 months after transplantation. After birth of 1-3 children the uterus will be removed by hysterectomy,

Psychiatric disorders in women with prolonged infertility with or without IVF/ICSI failure will be included then a questionnaire will be applied plus psychiatric examinatins

The investigators plan to retrospectively analyze clinical data from 14,189 fresh ICSI cycles in Reproductive and Genetic Hospital of CITIC-Xiangya from January 2016 to December 2017.The investigators will regard total progressive sperm number of 2 x 10^6 after pretreatment as the boundary value, and will divide total progressive sperm number of 2 x 10^6 after pretreatment into 2 x 10^6 or higher and < 2 x 10^6 groups, and will further divide < 2 x 10^6 group into: = 0, (0,10^6], (10^6, 2 x 10^6) three groups. Propensity score matching will be used to balance the baseline data between four groups. The matching variables are age, female BMI, AFC, AMH and ICSI.

In order to increase the likelihood of achieving IVF-treated pregnancy, good quality embryo transfer is important. To get good quality embryos, good quality gametes are needed. The selection of sperm is regulated according to the changing and mobility characteristics of today's conditions. The choice of multi-fluid sperm is thought to provide better sperm to obtain the environment in physiological conditions. Better embryo transfer to achieve better sperm elongation will increase the likelihood of pregnancy.

Investigators wants to analyze the differences considering the country of origin, ethnicity, characteristics, reproductive history and habits of participants undergoing in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) treatment as well as the stimulation outcome in regards to stimulation dosages and egg cell yield.

Birth weight (BW) is higher after frozen embryo transfer (FET) than after fresh embryo replacement. No study has compared the BW of siblings conceived using the same oocyte/embryo cohort. The aim of this study was to determine whether the freezing-thawing procedure is involved in such difference.
