Active clinical trials for "Infertility"

hCG and GnRH agonist can be used to induce final oocyte maturation and ovulation in IVF cycles. These two approaches will be compared in this study in terms of pregnancy rates and embryological data using patients with hyper-response to IVF drugs.

The aim of this study is to compare between body-temperature to room-temperature contrast media used during hysterosalpingography. We hypothesize that warmed medium will reduce pain associated with the procedure.

aim of that study is to compare the effect between autologous intrauterine Platelet-Rich Plasma instillation and three snip hysteroscopic endometrial scratching for thinned endometrium.

The endometrium becomes receptive as a result of a series of timed hormonal events during the menstrual cycle. The exposure of the endometrium to progesterone after ovulation initiates morphological and functional alterations that result in the change from a pre-receptive to a receptive endometrium. The morphological changes observed on histology for each specific day after ovulation were described by Noyes and his colleagues in 1950. An endometrial biopsy that shows a difference of more than 2 days between the histologic dating and actual day after ovulation is considered to be "out of phase" However, the clinical application of the Noyes criterion is relatively limited. We have verified the Noyes criterion in natural cycle in previous study which conducting endometrial biopsies respectively on day 3, 5, 7, 9 and 11 of post-ovulation (PO+3/5/7/9/11)(unpublished data). The clinical value of the endometrial histological dating in RIF patients in natural cycle is still to be answered. In this study, we tried to investigate the clinical effects of pFET in unexplained RIF patients according to the use of classic histologic endometrial dating to estimate the timing of the window of implantation and to adjust embryo transfer time in natural cycle.

The fertility treatment in vitro fertilisation (IVF), sometimes including intra-cytoplasmic sperm injection (ICSI), involves the creation of embryos in a laboratory. These embryos are then transferred into the womb of the patient with the hope of a resulting pregnancy and live birth. Embryos can also be cryopreserved (frozen) and stored, and then later replaced in a cycle called frozen embryo transfer (FET). There are several methods of preparing the patient's womb to receive the frozen-thawed embryo(s) but commonly embryos are replaced during a medicated cycle. Usually oestrogen and progesterone are administered to prepare the womb lining for embryo transfer at the appropriate time, and in addition a drug called a GnRH antagonist is administered to prevent a women's own hormones from interfering with this process as it is thought this might lead to higher numbers of cycles being cancelled. However, there is some suspicion that this drug (GnRH antagonist) may not be required and that women are using this drug unnecessarily. Some clinics do not use GnRH antagonists in FET cycles, but the investigators do not know if they have higher rates of cancelled cycles as a result. This pilot study aims to compare cycles of medicated FET using oestrogen and progesterone, either with or without pituitary suppression in the form of GnRH antagonist (Cetrotide), in patients over the next 18 months who are planning FET cycles at Oxford Fertility, UK to find out if both give the same chance of having a baby, which treatment is better for patients and to assess the feasibility of undertaking a future larger study. Cetrotide is a marketed and well-known medication and any risk or serious adverse effects are unlikely. The study is an open label prospective randomised controlled trial. Funding for the medication (Cetrotide) is provided by Oxford Fertility.

Since the first "tube baby", Louise Brown, was born in the United Kingdom in 1978, many infertile couples have been benefitted from in vitro fertilization and embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI). Although a late starter, China is developing rapidly in ART and playing a more and more important role in the area of reproductive medicine. In spite of the continuous development in ART, so far, the overall success rate of IVF/ICSI is still hovering around 25-40%. There are many factors influencing the success rate of IVF/ICSI. Among them, an appropriate controlled ovarian hyperstimulation (COH) protocol is directly associated with the number of oocyte retrieved, as well as the number and quality of embryos, which exert an important influence on the success rate of IVF/ICSI. The luteal phase pituitary down-regulation protocol is one of the most widely used COH protocols in clinical practice, particularly in China. Though effective, it may lead to an increased incidence of ovarian hyperstimulation syndrome (OHSS), as well as a negative impact on endometrial receptivity. The coping strategy is to freeze all the embryos and transfer in the next cycle. Though avoiding the above mentioned adverse effects, such strategy increases the time to pregnancy (TTP) and therefore results in certain psychological and economic burdens for infertile couples. In recent years, some Chinese researches applied the early follicular full-dose down-regulation protocol that is always performed to women with endometriosis to a more general IVF/ICSI population and found a clinical pregnancy rate of 64% in the fresh embryo transfer cycle, much higher than that of the luteal phase down-regulation protocol. Furthermore, since this protocol decrease the risk of progesterone elevation on hCG day, it increases the fresh embryo transfer rate and shortens TTP. Given most studies regarding the effectiveness and safety of the early follicular phase full-dose down-regulation protocol are retrospective studies, the results may be biased by several confounding factors. Therefore, we would like to conduct a multicenter, randomized controlled trial to compare the pregnancy outcome and safety indicators between the early follicular phase full-dose down-regulation protocol and the luteal phase down-regulation protocol.

Multi-centered, randomized controlled study, evaluating the safety and efficacy of the Ohana IVF Sperm Preparation Kit vs. a standard IVF sperm preparation kit.

This study evaluates the difference of imaging diagnostic quality and fertility promoting effect in the diagnosis and treatment of infertility by hysterosalpingography between using ethiodized poppyseed oil and the second-generation non-ionic monomer contrast. Half of participants will receive ethiodized poppyseed oil for hysterosalpingography, while the other half will receive the second-generation non-ionic monomer contrast for hysterosalpingography.

The effects of two different sedation protocols during transvaginal oocyte retrieval will be investigated on propofol consumption as a rescue sedative and on IVF success. One group will receive dexmedetomidine and fentanyl while the other will receive midazolam and remifentanil.

Infertility is estimated to affect 15% of reproductive age couples worldwide and is defined as the inability to conceive after 12 months of unprotected sex for women under 35 or 6 months for women over 35 and is associated with stress, especially due to psychological factors such as anxiety, frustration and depression. In addition, women seeking treatment for pregnancy suffer additional stressors - significant emotional burdens and physical changes that can increase stress and anxiety levels. The possibility of an association between emotional stress and pregnancy outcome in women undergoing assisted reproduction treatment makes important therapies that address the psychological state of these women. Meditation and Reiki have been used to successfully reduce stress and anxiety in various health contexts. Reiki is a complementary health approach in which practitioners lightly place their hands on or just above a person to facilitate their own healing response. Reiki has been used as an adjunctive therapy to treat the symptoms common to infertile women seeking treatment, including anxiety, stress, depression, anger, despair and depression. Reviews of randomized controlled trials concluded that implementation of the Reiki intervention in health centers resulted in mental health benefits, including reduced tension, mental confusion, anxiety and pain as well as improved quality of life. Meditation can be defined as a form of mental training aimed at improving an individual's psychological capacities, such as attentional and emotional self-regulation. Meditation encompasses a family of practices that include mindfulness meditation, mantra meditation, yoga, tai chi and chi gong. Meditation has been used specifically in women undergoing IVF treatment to successfully reduce symptoms related to psychological distress. Studies measure the development of self-compassion, mechanisms of emotion regulation, and coping strategies related to infertility and quality of life in infertility. However, only one study showed a relationship between meditation and pregnancy rate. Unfortunately, the authors incorporated yoga and psychological approaches into meditation. Therefore, we designed this study to evaluate the impact of Meditation and Reiki on the outcome of assisted reproduction treatment.
