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.
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.
- Measurement of PGK2 and ACRV1 levels in the semen of infertile males undergoing testicular sperm extraction (TESE). - Correlate seminal levels of PGK2 and ACRV1 with sperm retrieval results and histopathology analysis of testicular biopsy samples.
The scarcity of evidence regarding the interchangeable use of different progestogens poses challenges, particularly in international egg donation and fertility preservation programs where standardizing protocols is crucial for achieving consistent efficacy, efficiency, and safety outcomes. Consequently, there's a pressing need for clinical studies to assess the effects of various progestogens on clinical outcomes in controlled ovarian hyperstimulation cycles. This study, a pioneering effort, aims to compare the effects of two progestogens on oocyte performance, safety, and efficiency in an egg donation program involving young, healthy, normo-responding patients.
This randomized controlled trial aims to assess whether treatment with denosumab can improve semen quality in infertile men selected by serum anti-mullerian hormone (AMH) as a positive predictive biomarker, and with severely impaired semen quality (concentrations between 0.01 million/mL to 2 million/mL).
This case-control study involving fertile and subfertile couples aims to identify male factors related to pregnancy likelihood, create a fertility index measure combining male and female factors to predict pregnancy likelihood, and examine how male factors relate to the semen physical and biological characteristics.
Ovarian response to gonadotropin stimulation plays a major role in the success of in vitro fertilization (IVF). Anti-müllerian hormone (AMH), inhibin B, and antral follicle count (AFC) are ovarian reserve markers and also predictors of the ovarian response, as they correlate with the number of oocytes retrieved. Ovarian responsiveness can also be assessed through the Follicular Output Rate (FORT), which evaluates the proportion of follicles that developed during stimulation by the ratio of PFC (preovulatory follicle count) to AFC. FORT highlights that some follicles do not respond to the FSH; therefore, this project proposes an endocrinological approach to this issue by relating AFC to inhibin B and AMH ㅡ hormones produced by granulosa cells, but at different stages of folliculogenesis and with endocrine and paracrine functions, respectively. The inhibin B/AFC and AMH/AFC ratios correlated with FORT and the number of oocytes retrieved may help elucidate the mechanisms involved in follicular responsiveness. A prospective cohort study will be conducted with patients of the Insemine Center for Human Reproduction. Antral follicle count and AMH measurement will be performed before IVF cycle initiation, and inhibin B measurement will be carried out on a blood sample collected on the fifth day of ovarian stimulation. The primary outcomes will be the Follicular Output Rate (FORT) and the number of oocytes retrieved. Secondary outcomes include the number of metaphase II oocytes, oocyte quality, fertilization rate and embryo quality.
One of the most sensible factors in IVF culture conditions is the susceptibility of gametes and embryos to an induced increase in reactive oxidative species (ROS) caused by the artificial environment. This study aims to evaluate the impact of using antioxidant-supplemented media during culture to evaluate embryo ploidy rates in a prospective randomized trial using sibling oocytes.
In Vitro Fertilization (IVF) success is below 40%, with Embryo Transfer the leading cause of IVF failure. This clinical investigation aims to evaluate if the levels of an intrauterine biomarker dissolved in the uterine fluid (alone or as a complex biological marker) can predict the outcome of embryo transfer.
