Active clinical trials for "Infertility"

The management of suboptimal ovarian responders remains a challenging task in IVF. These patients are frequently managed with an intense stimulation protocol of ovarian stimulation in order obtain the maximum number of embryos and, therefore, maximize the cumulative live birth rate. However, the concept of "the more the better" has been recently defied by the one of "mild stimulation". Defenders of this protocol state that with mild stimulation only the best quality oocytes are allowed to grow and, therefore, higher quality embryos will be obtained. However, the impact of the intensity of ovarian stimulation on embryo quality is far from consensual. Moreover, its effect on early embryo development has never been evaluated. Therefore, the investigators set out to perform this randomized controlled trial comparing the number of GQB and the morphokinetic parameters of early embryo development in infertile patients undergoing two different intensities of ovarian stimulation, a milder approach (CC plus 150 IU daily dose of rFSH) and a more intense approach (300 IU daily dose of rFSH).

Poor fertilisation plays a significant role in poor artificial reproductive technique outcomes. Male factor infertility accounts for a large portion of such cases. Several modalities have been proposed as a solution, including physiological intra-cytoplasmic sperm injection (PICSI). PICSI is a technique used to select the sperm to use in intra-cytoplasmic sperm injection (ICSI) treatment. It involves placing sperm with hyaluronic acid, a natural compound found in the body. PICSI identifies sperm that can bind to hyaluronic acid and these sperms are selected for use in treatment. Some studies have suggested that PISCI may be advantageous to reduce miscarriage. However, the evidence is not strong and it remains unknown if PICSI is effective in a selected group of couples with a history of poor fertilisation. Based on previous medical records, we observed a higher clinical pregnancy rate (CPR) and a trend towards lower miscarriage rates with PICSI. To verify the findings and address the clinical gap, we propose a randomised controlled trial (RCT) with 234 couples (117 in each group) to evaluate the effectiveness of PICSI comparing with ICSI for improving CPR and reducing miscarriage rate in couples with a fertilisation rate of <50% in their first cycle of ICSI.

In the early stage, our team found that Acupuncture intervention in freeze-all IVF cycles can improve the clinical pregnancy rate. In order to further study the role of Acupuncture in improving the pregnancy outcome of IVF-ET in infertility. A randomized controlled clinical trial will be used in this study. 90 infertile patients are randomly divided into two groups. The control group will be treated with conventional modern medicine, and the treatment group will be treated with Acupuncture on the basis of conventional modern medicine. The intervention starts from the 5th day of the menstrual cycle and lasts to the day before IVF-ET. The number of oocytes, antral follicles, AMH, serum FSH, and clinical pregnancy rate will be observed to evaluate the effect of Acupuncture on the improvement of pregnancy outcome. In addition, all of the participants will be asked to complete the self-evaluation of the anxiety/depression scale on the 7th day of the menstrual cycle, before and after transplantation, to analyze the emotional changes of the subjects during the study. We observe the safety and health economic indicators of Acupuncture treatment, so as to improve the overall efficacy of TCM Combined Application in assisted reproductive technology in the future.

Randomized control trial to determine if performing the US Health and Human Services recommended amount of weekly physical activity during ovarian stimulation will differentially affect mental health or clinical outcomes of individuals who are usually active, insufficiently active, or inactive in their everyday lives. The goal overall is to assess for safety and value of physical activity during fertility treatment.

The purpose of this randomized controlled trial is to investigate if immediate single blastocyst transfer (in the first menstrual cycle following oocyte retrieval) is non-inferior to standard postponed single blastocyst transfer (in the second or subsequent menstrual cycle following oocyte retrieval) in modified natural cycle frozen-thawed embryo transfer (mNC-FET) in terms of live birth rate.

The management of endometriosis-related infertility remains controversial. In particular, there is an equipoise for infertile women with endometriotic lesions detected at ultrasound. These women can be managed with either surgery or in vitro fertilization (IVF). The two approaches radically differ and they have never been compared with a randomized trial. As a consequence, affected women currently receive contrasting information and the mode of treatment substantially differ among centres, reflecting the local expertise of physicians rather than clinical needs. The present study aims at clarify whether IVF could be superior to surgery in infertile women with endometriotic lesions detected at ultrasound. This topic will be addressed comparing the two approaches in terms of effectiveness and cost-effectiveness. In addition, the study will disentangling whether the endometriosis-related systemic inflammatory mechanisms may have an impact on the quality of folliculogenesis and on IVF outcomes. This specific objective will be pursued through the characterization and analysis of circulating extracellular vesicles (EV)-immunologic, proteomic and miRNA signatures and measurement of steroid hormones in follicular fluid.

The purpose of this study is to investigate whether oral Gushen Antai pills supplementation for luteal phase support will improve ongoing pregnancy rate in women with normal ovarian reserve in fresh embryo transfer cycles.

Autologous PRP intra ovarian infusion may restore ovarian function, may promote folliculogenesis and may improve hormonal profile of women in menopause.

The investigators have previously confirmed a clinical hunch that women with asthma have difficulties in becoming pregnant. The investigators found increased time to pregnancy (TTP) in women with asthma compared to non-asthmatic women (55 vs 33 months, p<0.001), furthermore, women with asthma had less successful pregnancies following fertility treatment (39.6 vs 60.4%, p=0.002). Treatment with omalizumab stabilizes the eosinophilic disease, through the systemic and most likely the anti-inflammatory pathways, which indicate a promising possibility to increase pregnancy rate. In a small real-life study in 2017, 5 patients with eosinophilic asthma who underwent in vitro fertilization (IVF), were treated with omalizumab prior to embryo transplantation; three out of the five women became pregnant. Lastly, the two remaining patients had several treatments with omalizumab, but did not become pregnant. This real-life study calls for further investigation. By targeting systemic inflammation with omalizumab treatment the aim is to increase asthma control before and during pregnancy. A treatment strategy aiming at improving overall inflammatory control may increase fertility, but also reduce well known maternal and perinatal adverse pregnancy outcomes such as pregnancy loss, preeclampsia, gestational diabetes, low-birth weight, small for gestational age (SGA), preterm delivery. Study design: A randomized control trial with omalizumab and placebo, stratified for blood eosinophil count, is therefore needed. A randomized, double blinded, parallel group, study to evaluate the difference between omalizumab (O) and placebo (P) on pregnancy rate in patients with atopic asthma.Treatment schedule: After collection of material (blood samples, sputum, secretion of the vagina, secretion of the rectum, microbiota) 6th day (±1 day) of the menstrual cycle, the patients will be randomized in either the omalizumab group or the placebo group. No collection of material will be done at the time of enrollment, as this will be on different time of the female cycles. The treatment is initiated with one injection with weight and serum-immunglobulin E balanced omalizumab or one injection placebo. After omalizumab treatment at ovulation it will again be collected material (blood samples, sputum, secretion of the vagina, secretion of the rectum, secretion of the uterus, microbiota). If no pregnancy has occurred after first IVF cycle, this will be repeated for 3 consecutive IVF cycles in total or until pregnancy has occurred. Outcome: The primary out-come is efficacy of omalizumab, compared to placebo, in increasing pregnancy rate in females with asthma. Secondary out-comes are changes in the inflammation in lungs/systemic/uterus, change in microbiota in the uterus and lungs, pregnancy loss, asthma control and biomarkers in the blood/lungs/uterus.

A randomized comparison of the live birth rate between the progestin-primed ovarian stimulation protocol and the gonadotrophin releasing hormone antagonist protocol in patients undergoing in vitro fertilization Research question Does the live birth rate of the progestin-primed ovarian stimulation protocol comparable with the GnRH antagonist protocol for patients undergoing IVF? Design This is a randomized controlled trial. Research plan Population: Infertile women who have medical indication for IVF will be recruited for study if they fulfil the selection criteria. Intervention: Women will receive oral dydrogesterone 20mg daily from Day 3 till the day of ovulation trigger. Comparator: Women will receive antagonist (Cetrorelix 0.25mg) once subcutaneously daily from day 6 of ovarian stimulation till the day of the ovulation trigger. Outcomes: The primary outcome is the live birth rate the first FET. Ovarian stimulation, egg retrieval, embryos frozen and frozen embryo transfer will be performed according to the standard operating procedures of the centres.
