Filter by: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.
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.
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 study 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.
Evaluation of treatment with Coenzyme Q10 and L-Carnitine on Semen Parameters in Infertile men with Idiopathic Oligoasthenoteratospermia
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.
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.
During two none subsequent natural menstrual cycles healthy female participants will be subjected every second day to blood sampling and 3D-ultrasound examinations. Together with four other key hormones the concentration of AMH (anti-Muellerian Hormone) will be measured in the serum.
TetraSOD® is a unique marine phytoplankton (Tetraselmis chuii) SOD-rich ingredient that is grown under patent-protected technology exclusively designed by the company Fitoplancton Marino, S.L. (Spain). In a previous pilot trial, the ability of TetraSOD® (dose: 250 mg/day) to improve semen characteristics in idiopathic infertile men after three months of treatment was assessed, revealing significant improvements in almost all of the analyzed parameters. In a further clinical trial close to finish (ClinicalTrials.gov Identifier: NCT04864314) using the same dose, such positive results have been tested again in a higher number of patients, and additional parameters have been included in order to gain insights into the sperm physiological changes that underpin the improvement in semen quality. In this new clinical trial, an intermediate dose (125 mg/day) is going to be tested in an attempt to determine a range of TetraSOD® dosage being clinically active for the treatment of male infertility.
A prospective study that will take place in the hydrosonography clinic, comparing patients with an intact uterus to those who had a caesarean section. Eligible patients will preform a transvaginal ultrasound for evaluation of presence of a niche. After fixation of the transcervical catheter, we will flush 2 ml sterile NaCl 0.9% into the uterine cavity and aspirate the fluid. After collecting all samples, the samples will be snap frozen and stored at -80o C, until they undergo an immunological analysis.
The purpose of this study is to evaluate the safety of a single injection of GenSci094 during Controlled Ovarian Stimulation up to 1 year old of the infants from previous studies.
