NCT ID: NCT06360471 Recruiting - Cancer Clinical Trials

Fertility Preservation and Pregnancy and Offspring Health Outcomes in Female Cancer Patients: A Multicenter, Prospective, Cohort Study

Start date: October 1, 2023
Study type: Observational [Patient Registry]

To explore whether there is a significant difference in the cumulative live birth rate and maternal and child health outcomes between cancer patients who undergo or do not undergo fertility preservation before receiving anti-tumor treatment and non-cancer patients who undergo assisted reproductive technology treatment/natural pregnancy. This study will be conducted in the Clinical Center of Reproductive Medicine, First Affiliated Hospital of Nanjing Medical University. 2800 women diagnosed with malignant cancers who has desire to reproduce will be enrolled in this study. Statistical analysis of the data will be performed.

NCT ID: NCT06358794 Completed - Infertility, Male Clinical Trials

Machine Learning Based-Personalized Prediction of Sperm Retrieval Success Rate

Start date: June 1, 2022
Study type: Observational

Non-obstructive azoospermia (NOA) stands as the most severe form of male infertility. However, due to the diverse nature of testis focal spermatogenesis in NOA patients, accurately assessing the sperm retrieval rate (SRR) becomes challenging. The current study aims to develop and validate a noninvasive evaluation system based on machine learning, which can effectively estimate the SRR for NOA patients. In single-center investigation, NOA patients who underwent microdissection testicular sperm extraction (micro-TESE) were enrolled: (1) 2,438 patients from January 2016 to December 2022, and (2) 174 patients from January 2023 to May 2023 (as an additional validation cohort). The clinical features of participants were used to train, test and validate the machine learning models. Various evaluation metrics including area under the ROC (AUC), accuracy, etc. were used to evaluate the predictive performance of 8 machine learning models.

NCT ID: NCT06358547 Not yet recruiting - Infertility Clinical Trials

Preimplantation Genetic Testing for Aneuploidy (PGT-A) in Women Aged 37-41 Years

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

A multinational multi-centre, randomized, controlled non-blinded trial with participation of three fertility clinics in Denmark and one in Spain to assess the efficacy and safety of preimplantation genetic testing for aneuploidy (PGT-A) in 37-41-year-old women.

NCT ID: NCT06356753 Completed - Endometriosis Clinical Trials

EndoxOmics : Exposome, Endometriosis and Fertility

Start date: September 1, 2019
Study type: Observational

For several years, the effects of environmental pollution on human health have been a growing concern for the scientific community and public authorities. Among the many known chemical contaminants, persistent organic pollutants (POPs) are of particular concern because of their properties as endocrine disrupters, bioaccumulation and biomagnification. The associations between environmental pollutants, endometriosis and infertility remains poorly understood. The objective of this exploratory non interventional monocentric study conducted in the University Hospital of Nantes, is to identify endogenous molecular profiles associated with endometriosis and related infertility. This project implements an exploratory approach combining exposure and metabolomics approaches based on high-resolution mass spectrometry to identify exposure and metabolomics profiles associated with infertility, and biomarkers for potential prognostic application.

NCT ID: NCT06344585 Completed - Infertility Clinical Trials

Drop-out of Infertile Couples: a Large Single Center Experience Over 10 Years

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

Conducted at a single-center, this prospective-retrospective study focused on all couples who initiated their journey at the Fertility Center of Humanitas Research Hospital, Rozzano (Milan), Italy. The prospective study focused on the couples whose first consultation occurred in 2021. A tailored questionnaire was administered via telephone by staff members to gather insights into the personal reasons for treatment discontinuation among non-returning patients. Conversely, the retrospective arm included all infertile couples initiating treatment between January 2012 and December 2021 at the Fertility Center. Data encompassing personal history and demographic details were extracted from the internal database of Humanitas Fertility Center to assess the factors involved in a treatment discontinuation.

NCT ID: NCT06342856 Recruiting - Clinical trials for Infertility Unexplained

Evaluation of Treatment With Coenzyme Q10 and L-Carnitine on Semen Parameters in Infertile Men With Idiopathic Oligoasthenoteratospermia

Start date: June 15, 2023
Phase: Early Phase 1
Study type: Interventional

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

NCT ID: NCT06335706 Not yet recruiting - Infertility, Male Clinical Trials

The Influence of Fit of Underpants Worn on Semen Quality

Start date: March 2024
Study type: Observational

The goal of this observational study is to investigate the impact of underpants fit among Thai males attending the Infertility Clinic, whether alone or with their spouses. The main questions it aims to answer are: - Assessing the effect of underpants fit on basic semen parameters and sperm DNA integrity. - Determining the prevalence of preferred type of underpants worn by Thai males. The participants will need to provide informed consent, complete a questionnaire consisting of 28 questions, and provide a semen sample.

NCT ID: NCT06332027 Not yet recruiting - Infertility, Female Clinical Trials

Accuracy of Hystro-Salpingo-Foam-Sonography (HYFOSY) as Tubal Patency Test in Comparison to Laparoscopy in Infertile Patients

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

Tubal patency testing is an essential part of female subfertility evaluation . Tubal abnormalities are seen in 30-40% of female subfertility patients . Laparoscopy with chromopertubation is considered to be the gold standard diagnostic procedure . Laparoscopy is an invasive test, with a risk of intra-abdominal bleeding, visceral damage, and risks related to general anaesthesia. Traditionally, Hysterosalpingography(HSG) is a less invasive less expensive first-step alternative, which has been used for decades with disadvantages such as radiation exposure, discomfort, or even abdominal pain. Hysterosalpingo-Contrast Sonography (HyCoSy) was introduced as an alternative using either contrast media or saline. The accuracy of HyCoSy is comparable to that of HSG and LSC being reference standards for tubal patency testing.However, hyperechogenic contrast media such as Echovist_ (Schering AG, Berlin) and SonoVue_ (Bracco, Milan)are either no longer available or not licensed for tubal patency testing. Hysterosalpingo-Foam Sonography (HyFoSy) was developed as an alternative for contrast HyCoSy and was introduced in 2010 as a first-line office tubal patency test.Foam is used in the HyFoSy technique to visualize the fallopian tubes and is created by rigorously mixing 5mlExEm_-gel (containing hydroxyethyl cellulose and glycerol,IQMedical Ventures BV, Rotterdam, TheNetherlands) with 5ml purified ExEm_-water. The ExEm_-foam is sufficiently fluid to pass the fallopian tubes and in the mean time sufficiently stable to show echogenicity for at least five minutes, which is an advantage over saline. In a review on safety aspects and side effects of ExEm-gel it was considered to be appropriate and safe for tubal patency testing. In 2017, HyLiFoSy combined with power Doppler (PD)(HyLiFoSy-PD) technique was described as a possibly less painful and easier to detect on ultrasound alternativeto HyFoSy and HyCoSy, which can be used whenever the contrast media used with both are either unavailable or is relatively expensive Ultrasound-based tubal patency tests include hysterosalpingo-contrast sonography (HyCoSy), hysterosalpingo-foam sonography (HyFoSy), and hysterosalpingo-lidocaine-foam sonography (HyLiFoSy)and have shown a high detection rate of tubal obstruction and good reproducibility with concordances from 83.8 to 100% with HSG, and from 78.1 to96.91% with lap-and-dye test. In addition, they allow for a single comprehensive assessment of the uterus and the fallopian tubes and it can be performed by the same specialist who indicates it, in the clinician's own office with it consequently being time efficient. Finally, some studies have shown an increase in the rate of post-procedure gestation.

NCT ID: NCT06330259 Completed - Clinical trials for Reproductive Sterility
