Active clinical trials for "Infertility"

The purpose of this study is to determine the physiological effects of weight loss on seminal parameters in male participants with reduced reproductive capacity. Learning more about the physiological role of weight loss on reproductive function and metabolic profile of overweight and obese men may give us a better understanding of male fertility and improve the management of patients with reduced fertility. The effects of weight loss on seminal quality are not well understood.

The present study aims to evaluate whether the use of a "dual trigger" can improve IVF outcomes, compared to GnRH agonist (GnRH-a) alone, in patients at high risk of OHSS undergoing a freeze-all cycle. By examining freeze-all cycles with frozen embryo transfer(s) (FET) only, we eliminate the potential confounding issue of inadequate luteal support to the endometrium and focus primarily on the effect of a "dual trigger" on oocyte quality and embryo potential. To our best knowledge, there have been no randomized, controlled trials conducted to address this hypothesis.

In donors or patients undergoing assisted reproduction treatments (ART) it is necessary to closely control ovarian stimulation to monitor the number and size of developing follicles. Oestradiol (E2) and progesterone (P4) are products of steroidogenesis. Their concentrations increase with the diameter of the growing follicle. In order to assess treatment response and support clinical decisions, accurate and reliable methods to measure E2 and P4 are essential. Measurement of both hormones, as well as monitoring of follicle growth through ultrasound measurements, is an important part of ovarian stimulation, requiring patients or donors to undergo multiple blood draws. It is often a physically and emotionally painful process, and the most convenient solution is the measurement of hormones concentrations in other biological fluids, such as saliva. Salivary diagnostic tests are a less invasive, inexpensive, and stress-free alternative. The current study pretends to evaluate the correlation between salivary ELISA assays and serum determination of progesterone and oestradiol concentrations in oocyte donors, and, also, evaluate the feasibility of doing saliva E2 and P4 determinations in the IVIRMA clinic labs.

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.

A non-inferiority, prospective parallel group, multi-center, randomized controlled trial to investigate whether selection of a single blastocyst for transfer using the deep learning tool, iDA, results in non-inferior clinical pregnancy rate compared to trained embryologists using standard morphology criteria.

Very little is known about how medical providers can help adolescent and young adults (AYAs) and their caregivers make decisions about fertility preservation (sperm banking) before beginning cancer treatment. The purpose of this study is to see if having a guided conversation about fertility preservation increases preservation rates and/or satisfaction with the decision among AYA males with cancer. The primary hypothesis is that compared to standard of care control group (routine fertility consult at diagnosis, n=20), AYAs in the intervention arm (routine fertility consult at diagnosis + FP Decision Tool and Facilitated Conversation by trained interventionist) will have higher rates of FP uptake. The secondary hypothesis is that families in the intervention group will report better FP decision quality compared to those in the control arm.

The aim of the project is identify new biomarkers and/or prognostic factors in order to develop personalized strategies to prevent the onset of tumor and/or non tumor comorbidity in infertile men.

Infertile women attending for PGT at the Centre of Assisted Reproduction and Embryology, Queen Mary Hospital and Kwong Wah Hospital will be recruited during ovarian stimulation for IVF. Subsequently, they will be randomly assigned on the day of oocyte retrieval by a laboratory staff into one of the following two groups in a 1:1 ratio : (1) the microfluidic chip group and (2) the density gradient centrifugation group for sperm preparation and subsequent use in fertilization. Other IVF procedures will be the same as the standard practice of the Centre. Both women and clinicians will be blinded from the group allocation i.e. a double blind study.

The purpose of this study is to determine if physiological measures of stress, measured by the non-invasive OTO device, are significantly correlated with IVF outcome.

We recently identify in our previous study 'NCT052115832' the progesterone levels for the embryo transfer in natural thaw cycles. Since it is shown that progesterone levels work better than LH levels in order to detect the time to transfer, we aimed to show the pregnancy outcomes of the natural thaw cycles which had the transfer date regarding the progesterone levels.
