NCT ID: NCT06413771 Completed - Clinical trials for Infertility Unexplained

Only Gonadotropin Vs. Letrozole Combined Gonadotropin Stimulation in IUI Cycles

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

The present randomized controlled study aims to investigate the effectiveness of a combined regimen of letrozole and gonadotropin with dose adjustments based on body mass index (BMI) compared to a conventional only gonadotropin regimen in intrauterine insemination (IUI) cycles for couples experiencing unexplained infertility. The study was conducted at a tertiary university hospital's Assisted Reproductive Technologies (ART) center from January 2023 to January 2024. Couples with unexplained infertility were enrolled based on comprehensive assessments, and randomization was performed based on national ID (odd or even). The Conventional Only Gonadotropin (COG) group received recombinant FSH based on body mass index (BMI), while the Combined Letrozole-Gonadotropin (CLG) group received letrozole followed by gonadotropin with dose adjustments based on BMI. Ovulation induction and IUI were performed according to standard protocols. Clinical outcomes, gonadotropin consumption, and pregnancy rates were compared between groups. Among 317 IUI cycles, 131 couples with unexplained infertility were randomized (CLG: 61, COG: 70). Demographic parameters were similar between groups. The CLG group had lower daily gonadotropin doses (67 ± 18 IU/D vs. 76 ± 11 IU/d, p=0.01) and total gonadotropin consumption (750 IU vs. 825 IU, p=0.01) with comparable ovulation and clinical pregnancy rates. The COG group exhibited higher multiple pregnancy rates, although not statistically significant (CLG vs. COG; 1/61 vs. 3/70, p=0.4). The study suggests that the combined letrozole and gonadotropin regimen with BMI-based dose adjustments in IUI cycles for unexplained infertility is associated with reduced gonadotropin consumption and potentially lower multiple pregnancy rates.

Evaluation of treatment with Coenzyme Q10 and L-Carnitine on Semen Parameters in Infertile men with Idiopathic Oligoasthenoteratospermia

NCT ID: NCT06290518 Completed - Clinical trials for Infertility Unexplained

Modulation of Reproductive Microbiota by Ligilactobacillus Salivarius CECT5713

Start date: September 1, 2020
Phase: N/A
Study type: Interventional

The objective of the project is to elucidate if the oral administration of Ligilactobacillus salivarius CECT5713 is capable of improving the rates of term pregnancies in couples with infertility problems of unknown cause. On the other hand, the project is aimed to detect microbiological, immunological and hormonal markers that allow the identification of couples in which the administration of the strain could be particularly effective. This is a randomized, double-blind, parallel-group controlled nutritional intervention study. The intervention (Ligilactobacillus salivarius CECT5713 or placebo) will be performed during the 6 months prior to the fertility treatment and during the first IVF cycle (estimated 1-2 months). In case of pregnancy, the woman will continue the treatment until 12 weeks of gestation.

The Role of Granulocyte Colony Stimulating Factor in Embryo Transfer Outcomes

Start date: March 20, 2024
Phase: Phase 4
Study type: Interventional

The goal of this clinical trial is to test the effect of granulocyte colony-stimulating factor (G-CSF, A.K.A. Filgrastim) in infertility patients undergoing in vitro fertilization (IVF) treatment. The main question it aims to answer is: Can in vitro fertilization-embryo transfer (IVF-ET) outcomes be improved by supplementing the transfer media with Granulocyte colony-stimulating factor (GCSF)? Participants will undergo their embryo transfer as per the normal clinic protocol but will be randomized to either receive the standard embryo transfer media or the GCSG-supplemented transfer media. Researchers will compare the GCSF and standard transfer media groups to see if clinical outcomes are improved (i.e., implantation rate, pregnancy, clinical pregnancy rate, live birth rate).

NCT ID: NCT05946655 Completed - Clinical trials for Infertility Unexplained

Diagnostics of Chronic Endometritis in Infertility

Start date: April 1, 2021
Phase: N/A
Study type: Interventional

Chronic endometritis (CE) is characterized by the presence of atypical plasma cell infiltrates (CD138 positive) in the endometrial stroma. Recent analyzes suggest that CE adversely affects fertility by reducing endometrial receptivity, impairing decidualization and uterine contractility, thus increasing the risk of recurrent pregnancy loss and implantation failure. It is likely that a significant proportion of idiopathic infertility cases are due to CE. The diagnosis of CE is a challenge because the clinical examination and transvaginal ultrasonography are considered non-specific. The recent scientific research has been aimed at identifying hysteroscopic CE diagnostic criteria and establishing the compatibility of ultrasonographic, hysteroscopic, histopathological (including the use of immunohistochemical testing with antibodies against human CD138) and microbiological diagnoses. Preliminary literature results suggested that successful treatment of CE with antibiotics could improve live birth rates.

NCT ID: NCT05824819 Recruiting - Endometriosis Clinical Trials

Endometriosis and Peritoneal Dysbiosis

Start date: May 1, 2023
Phase: N/A
Study type: Interventional

Endometriosis is a complex clinical syndrome that impairs many aspects of a woman's life, characterized by a chronic estrogen-dependent inflammatory process, mainly affecting the pelvic organs, with ectopic presence of tissue analogous to the uterine mucosa (endometrium). Despite intensive research in the field of etiopathogenesis, its cause has not yet been determined, and treatment remains symptomatic. Endometriosis causes two main complications, i.e. pelvic pain syndrome and infertility. In recent years, thanks to the analysis of the human microbiome, it has become possible to deepen the knowledge of the physiological and pathological interactions between microorganisms inhabiting various body areas and the host. Bacteria may enter the peritoneal cavity in the mechanism of retrograde menstruation and translocate from the intestines, and then promote the development of local and systemic inflammation, leading to the symptoms of endometriosis. The study is to determine whether the presence of a specific intestinal, peritoneal and uterine microbiome correlates with endometriosis stage and whether its presence predisposes to increased pain or infertility. Concordance or divergence of bacterial populations inhabiting the peritoneal and uterine cavities could have clinical implications, i.e. the possibility of empirical antibiotic therapy in patients undergoing only endometrial aspiration biopsy and not opting for surgical treatment.

NCT ID: NCT05789407 Completed - Endometriosis Clinical Trials

Organic Pollutants in Pelvic Endometriosis

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

The health toxicity of polycyclic aromatic hydrocarbons (PAHs), present in air and food, generated during energy production and waste incineration, is well known. PAHs can activate the aryl hydrocarbon receptor, which may interact with classic estrogen receptors and modify estrogen-dependent inflammation in endometriosis. There is no data on the hypothetical role of PAHs in the etiopathogenesis of endometriosis. The aim was to compare PAHs concentrations in visceral fat in women with endometriosis and idiopathic infertility.

Relation Between MicroRNA 203 and 210 and Sparing the Laparoscopic Examination in Cases of Unexplained Infertility

Start date: November 7, 2020
Phase: N/A
Study type: Interventional

The study targets to evaluate the role of estimation of plasma expression levels of gene of microRNAs 203 and 210 in helping to diagnose and grade endometriosis. The study included women with unexplained infertility and clinical picture suggestive of presence of endometriosis were divided randomly into two groups: Control and study groups. All patients underwent exploratory laparotomy for diagnosis and grading of endometriosis if present. Patients of study group gave blood samples for estimation of plasma expression levels of microRNA 203 and 210 using qRT-PCR procedure.
