Active clinical trials for "Infertility"

Hysterosalpingography (HSG) and hysterosalpingo-foam sonography are two methods to assess tubal patency during fertility work-up. This study aims to investigate the effectiveness of tubal flushing with oil-based contrast during HSG compared to tubal flushing during HyFoSy in women undergoing fertility work-up. The hypothesis is that tubal flushing with oil-based contrast during HSG leads to more live births than tubal flushing during HyFoSy.

This study aims to assess the association of Anti-Müllerian hormone (AMH) with polycystic ovarian syndrome, premature ovarian insufficiency and fertility. The main objectives include the following: To study the level of serum AMH in women with PCOS and to evaluate the utility of serum AMH in the diagnosis of PCOS. To evaluate the level of serum AMH in women with POI and to evaluate the utility of serum AMH in the management of POI. To evaluate the associations of basal AMH level with FSH level and AFC respectively for women undergoing ART treatment. To determine the optimal regimen of gonadotropin for ovarian stimulation for women undergoing ART treatment. To evaluate the predictive value of serum AMH in reproductive outcomes including oocyte quality, embryo quality, pregnancy loss, clinical pregnancy and live birth rate in women undergoing ART treatment.

As embryo ploidy is a crucial factor not only for implantation but also for maintenance of a pregnancy, the aim of this study is to evaluate the impact of the CS / isthmocele on the ongoing pregnancy rates and the implantation site in single euploid frozen embryo transfer, independent of the endometrial preparation approach.

An increased number of women has been infected by COVID-19 in the last 2 years SARS-CoV-2 infection could have a role in potential disturbances on hormon levels and human fertility Has not completely demonstrated COVID-19 effects on female reproductive function and further research can be undertaken. The proposed multicenter study will be simple and rapid, and attractive for the scientific community.

Rationale: A rising number of adenomyosis cases are being diagnosed in women in the age group of 30 to 40 years. This is due to a combination of better diagnostic imaging techniques and a higher number of women delaying the fulfilment of their fertility aspirations. The association between adenomyosis and pregnancy outcomes in women with subfertility has not been adequately explained by existing evidence due to lack of data on the association between the severity of adenomyosis, disease location, presence of symptoms and coexisting gynaecological conditions and pregnancy loss in women undergoing fertility treatment. There is a need to improve our understanding of prognostic features which would be beneficial in counselling women with adenomyosis undergoing fertility treatment and inform future management options. The investigators propose a research body of work aimed at improving our understanding of adenomyosis and its association with pregnancy loss. Objective: The aim of the study is to determine the association between adenomyosis and pregnancy loss in women undergoing assisted reproductive technology (ART) treatment. Study design: Prospective multicentre cohort study. The cohort will comprise of women with adenomyosis undergoing ART treatment and the control group will include women with normal uterus on baseline ultrasound scan undergoing ART treatment during the study duration. Settings: The study will be conducted at all main CARE fertility units, one of the largest providers of fertility treatment in the United Kingdom. Participant population with exposure and sample size: The cohort group will comprise of women diagnosed with adenomyosis on pre-treatment baseline ultrasound scan before ART treatment who satisfy the eligibility criteria and consent to participate in the study. The total sample size for this study will be 750 participants with 375 women in each arm. Recruitment will take place over the course of 18 months. Diagnostic tool for detection of exposure: The diagnosis of adenomyosis will be made using transvaginal ultrasound scan (TVS) (2D and 3D Ultrasound and applying Morphological Uterus Sonographic Assessment (MUSA) criteria. Schematic mapping system of adenomyosis severity proposed by Lazzeri and colleagues will be used to grade the severity of adenomyosis. Eligibility: Inclusion criteria: All women aged >18 years and ≤42 years undergoing IVF/ICSI cycle. Exclusion criteria: Women with coexisting fibroid uterus, endometrioma confirmed on USS or known laparoscopic diagnosis of endometriosis (with histological confirmation), untreated hydrosalpinx, uterine malformation, previous myomectomy, previous surgery for adenomyosis or inconclusive USS. Recruitment: All women undergoing pre-treatment pelvic ultrasound scans before ART treatment will be screened for adenomyosis at the participating centres. Women who meet the eligibility criteria will be provided with an information leaflet about the study. They will be enrolled in the study after informed consent is obtained. The severity of adenomyosis will be subsequently evaluated using stored 2D and 3D ultrasound scan (USS) images. Several demographic, clinical and treatment characteristics will be recorded for each participant. Control: To ensure adequate comparability of the cohort, women with normal uterus on baseline ultrasound scan during the study duration will be used as control and will be matched for the following variables: age, embryo quality, type of ART cycle (donor or self and IVF or ICSI) and number of embryos transferred. The eligibility criteria will be applicable to the controls as well. Outcome measures: Primary outcome: Pregnancy loss up to 24 weeks out of all pregnancies achieved. The pregnancy loss will include biochemical pregnancy loss, miscarriage, pregnancy of unknown location (PUL) and ectopic pregnancy. This will be reported per embryo transfer and per woman. Secondary outcomes:1. Implantation rate per embryo transfer (number of gestational sacs divided by number of embryos transferred) and per woman; 2. Biochemical pregnancy rate per embryo transfer (positive pregnancy test following embryo transfer) and per woman; 3. Clinical pregnancy rate per embryo transfer (presence of at least one intrauterine gestational sac on ultrasound) and per woman; 4. Ongoing pregnancy rate per woman (defined as a live pregnancy at 12 weeks onwards); 5. Live birth rate after 34 weeks per woman. Subgroup analysis: We will carry out subgroup analysis according to specific patient characteristics. These analyses will include, but not necessarily be limited to women with the following characteristics:1. Varying severity of adenomyosis; 2. Presence /absence of symptoms of adenomyosis; 3. Frozen vs. Fresh embryo transfer; 4. Short vs. long vs. ultralong ovarian stimulation protocol; 5. Recurrent miscarriages; 6. Other associations that may become apparent in post-hoc analyses.

Uterine leiomyomas (or fibroids) are a common disease (30% of women over 35 years of age) in women of childbearing age and can cause various symptoms such as menometrorrhagia, dysmenorrhoea, pelvic pain and heaviness, and infertility. Uterine artery embolisation, first used in France in 1990, is a safe, effective and less invasive therapeutic technique than surgical treatment (myomectomy or hysterectomy), particularly in the case of numerous and large fibroids. This technique is validated by the French National College of Gynaecologists-Obstetricians (CNGOF) as an alternative treatment for women who do not wish to become pregnant (grade A recommendation), but at present there is little reliable data concerning fertility, the occurrence of pregnancy and the obstetrical prognosis after uterine artery embolisation for fibroids. A recent systematic review of the literature with meta-analysis published very recently showed that 40.5% of patients with a desire for pregnancy were able to become pregnant after embolisation (CI: 33.3%-48.2%) but that the rates of miscarriage, obstetric complications and low birth weight were not negligible (respectively 33.5% (95% CI: 26.3-41%), 25.4% (95% CI = 13-40.2%) and 10% (95% CI = 6.2-14.6%) (Ghanaati et al. 2020). In France, uterine artery embolisation is performed in more than thirty centres in women who have completed their parental project. On the other hand, in the absence of consistent literature, it is performed in patients of childbearing age, when it represents the only acceptable alternative or in the event of contraindication or refusal of surgery by the patient. To our knowledge, there is no large-scale French study to date on the impact of embolisation on fertility and pregnancy outcomes. The aim of this study is to compile a retrospective database of all cases of uterine artery embolisation for uterine pathology performed at the Georges-Pompidou European Hospital (HEGP) since 2007 and to assess the impact of embolisation on fertility in patients of childbearing age.

The investigators propose a pilot study to determine if autologous platelet-rich plasma (PRP) improves ovarian reserves and In-vitro fertilisation (IVF) outcomes in women with diminished ovarian reserve / premature ovarian insufficiency.

The aim of study is to evaluate the results of two different protocols for ovulation induction during IUI cycles. All patients undergo IUI cycles are randomly divided in to two groups. the first group is recombinant follicle stimulating hormone and the second group is the combination of recombinant follicle stimulating hormone with clomiphene citrate.

We recently identify in our previous study 'NCT052115832' the progesterone levels for the embryo transfer in natural thaw cycles. Since it is shown that progesterone levels work better than LH levels in order to detect the time to transfer, we aimed to show the pregnancy outcomes of the natural thaw cycles which had the transfer date regarding the progesterone levels.
