Active clinical trials for "Infertility"

The main objective of this non-inferiority randomized controlled trial is to assess the rate of blastocyst euploidy and the number of euploid blastocysts in women undergoing IVF/ICSI and treated with PPOS versus conventional ovarian stimulation based on the use of GnRH antagonist The hypothesis is that PPOS is associated with a rate of blastocyst euploidy similar to what found with the conventional ovarian stimulation. In other words, the number of euploid blastocysts that can be obtained with the PPOS strategy is expected to be the same obtained with conventional ovarian stimulation. Moreover we expect to find non significant differences in all intermediate outcome of the IVF cycles, such as in the rate of premature LH surge, in the rate of patients with elevation of Progesterone on the triggering day, in FSH consumption and length of stimulation, in the rate of poor response and hyperresponse, in number of retrieved and mature oocytes, in fertilization and blastulation rate, in the number of available blastocysts and in the morphological quality of blastocysts

In the early stage, the preliminary study found that traditional Chinese medicine (TCM) intervention aimed at Nourishing kidney and regulating blood circulation in freeze-all IVF cycles can improve the clinical pregnancy rate. In order to further study the role of TCM 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 traditional Chinese herbs on the basis of conventional modern medicine. The intervention starts from the 5th day of the menstrual cycle and lasts until the day before IVF-ET. After the transplantation, the TCM treatment continues for 14 days. The number of oocytes, antral follicles, AMH, serum FSH, and clinical pregnancy rate will be observed to evaluate the effect of TCM herbs on the improvement of pregnancy outcomes. In addition, all 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. The study will also observe the safety and health economic indicators of TCM treatment, so as to improve the overall efficacy of TCM Combined Application in assisted reproductive technology in the future.

This study is a randomized, double-blind, placebo-controlled, single dose, escalation, phase I clinical trial to evaluate the safety and tolerability of recombinant human follicle stimulating hormone Fc fusion protein injection (TWP-201) in healthy female subjects. The objective of the trial is to evaluate the safety and tolerability of TWP-201 in healthy female subjects.

This study is a prospective double blind randomized controlled trial to investigate the effect of red and white bahman on semen parameters, sexual hormones and DNA defragmentation in idiopathic oligospermic men .Include patients will take the medicine and placebo in different two case and control groups for 3 month and semen parameters and other variants at the start and end of study.

Two common SNPs are located in linkage disequilibrium in exon 10 of FSHR. The 2039 A>G variant is regularly analyzed to characterize the exon 10 haplotype. In the last years, it has been showed an influence of FSHR 2039 A>G on FSH levels, testicular volume, sperm concentration and the total sperm count. A recent Cochrane review showed a beneficial effect on live birth and pregnancy of gonadotrophin treatment for men with idiopathic male factor subfertility. Which FSHR polymorphism can benefit from FSH treatment is clinically very important, in particular for what regards nonidiopathic patients. In many andrological units, patients underwent adiuvant therapy with purified or recombinant FSH after varicocelectomy. FSH treatment in patients after varicocelectomy could improve spermatogenesis, but there aren't multicentric trials that confirm its validity. Usually, in our hospital only patients with a morphologic aspect of hypospermatogenesis underwent therapy with purified or recombinant FSH, because this therapy is not much useful in patient with Partial Sertoli-cell-only syndrome or maturation arrest. The purpose of our study is to correlate "non responder" patients who underwent FSH adiuvant therapy after varicocele surgery with a p.N680S FSHR polymorphism. Moreover the investigators suppose that "non responder" patients can beneficiate from a high-dose therapy with FSH. This is a prospective intervention study in which are recruited males with OligoAstenoTeratozoospermic (OAT) and varicocele. The partecipants will undergo subinguinal microsurgical varicocelectomy (Marmar technique) and needle aspiration testicular cytology (Foresta technique).

The basis for obesity's impact on reproduction is not well characterised and there is a controversy whether the key organ influenced by it are the ovaries or the uterus. Insulin sensitizers ameliorate insulin resistance in obese patients. This study seeks to determine if Metformin helps to increase fecundability by affecting the uterus in women undergoing ART. As a surrogate marker- flows in the uterus will be tested during the treatment.

The purpose of this study is to study the effects of letrozole and sequential clomiphene in ovulation and pregnancy in PCOS patients.

Premature ovarian insufficiency (POI) is a life-changing condition that affects women in their reproductive age. There is a lack of reports which focus on how to improve the reproductive outcome of these women who wish to conceive spontaneously or use assisted conception with their own oocytes. However, one could surmise that it is important to lower gonadotropin levels into the physiological range before embarking on any treatment, even if natural conception is the only choice for the woman/couple.

Recombinant gonadotropins are currently used for ovarian stimulation in women undergoing to IVF for infertility. Recently new flexible protocols have been introduced: the "single dose" and "multiple dose" protocol. The single dose protocol is performed just using Cetrorelix by the administration of a single injection of Cetrorelix 3 mg subcutaneous when the lead follicle is ≥ 14 mm. The multiple dose protocol consider the daily administration of Cetrorelix 0.25 mg subcutaneous or Ganirelix 0.25 mg subcutaneous when the lead follicle is ≥ 14 mm and until the realization of hCG criteriaThere are few data from letterature about the comparison of the efficacy in pitituary suppression and pregnancy outcome of Ganirelix and Cetrorelix. Objective: to compare the efficacy in pituitary gonadotropin suppression and IVF outcome of multiple dose flexible gonadotrophin-releasing hormone (GnRH) antagonist administration according to follicular size using daily injection of Cetrorelix or Ganirelix. Interventions : patients are randomly assigned in to Cetrorelix acetate group or Ganirelix acetate group. Multiple dose of Cetrorelix acetate (0.25 mg) or multiple dose of Ganirelix acetate (0.25mg) are administered when the lead follicle is ≥ 14 mm until hCG criteria are met.Oocyte maturation trigger is performed by the administration of subcutaneous r-hCG (250 μg) or of intramuscular hCG (10,000 IU). After 36 hour transvaginal oocyte retrieval is performed followed by ICSI and embrio transfer (72 hours later).

Infertility affects one in six couples. In a quarter of them, routine tests of semen quality, ovulation or tubal patency fail to reveal any abnormalities and the cause of infertility is unexplained. Acupuncture is being increasingly used by couples with all types of infertility and initial trials have suggested that it could be potentially beneficial in some cases. A number of systematic reviews of acupuncture in IVF have shown conflicting results, but there is no evidence to inform best practice in unexplained infertility. In addition, as an intervention, acupuncture is not cost neutral as it involves multiple visits for treatment sessions delivered by a skilled practitioner. Thus, while acupuncture could have the potential to increase live birth rates in women with unexplained infertility, the clinical and cost effectiveness of acupuncture needs to be confirmed in the context of a large randomized controlled trial.
