Active clinical trials for "Infertility"

The goal of this observational study is to understand the processes in the growing follicles development in more detail and to improve In Vitro Fertilisation (IVF) treatments. This involves measuring laboratory values in the blood, in the follicular fluid of the woman and in the sperm of the man as well as questionnaires concerning lifestyle factors. These values are then linked to the success of the fertility treatment to find out which of these values increase the success of the IVF treatment. Furthermore, the investigators want to investigate if there are differences between IVF treatments with or without hormonal stimulation of the ovaries.

The (motile sperm organelle morphology examination) MSOME allows the detection of sperm vacuoles that seems to be related to sperm DNA damage. The investigators hypothesized that couples with unexplained infertility could benefit from the injection of spermatozoa selected under high-magnification (x6600)

Premenopausal Women ages 18-42 will undergo a laparoscopic myomectomy. Prior to the myomectomy, adhesions will be assessed using a modified AFS scoring technique. All investigators will provide usual and customary care to research subjects during the first look laparoscopy. This includes the use of all standard practice anti-adhesive agents and heparinized irrigation fluids.V-Loc 180 suture will be utilized in all patients. All patients will then be evaluated by means of a second look laparoscopy (SLL) 6-12 weeks after the initial surgery and reevaluated via modified American Fertility Society scoring techniques. An independent reviewer will also score adhesions utilize a video recording made from the second look laparoscopic surgery. Patients will be contacted both 1 and 4 weeks post -op and assessed for complications. It is the expectation that patients will show no greater post-operative adhesion formation and a <1% complication rate. Time and ease of suturing will also be evaluated. It is expected that the V-Loc suturing technique will show significantly reduced suturing time, be easier to use, and will be associated with minimal adhesions.

This study will compare two alternative embryo culture systems. Embryos from each patient will be randomly assigned to one of two systems. One group will be cultured conventionally in oil-covered droplets in dishes. The other group will be assigned to an enclosed system.

Since the development in the last few years of the bipolar energy in the surgery by hysteroscopy, the hysteroscopic treatment of the submucosal uterine myoma can be performed by use of either monopolar or bipolar current. It seems that the use of the bipolar energy decreases the rate of adhesions but prospective data on the adhesion rate and fertility after the use of bipolar energy during the surgery are poor, and there is currently no recommendation as to the choice of technique to use. The main purpose of this study is to compare the rate of uterine adhesions six weeks after the surgical hysteroscopic treatment of uterine submucosal myoma, by using monopolar or bipolar energy. The pregnancy and spontaneous miscarriage rate will also be evaluated.

Patients who have shown previous implantation failures, despite transferring good quality and chromosomally normal embryos (diagnosed by PGT-A), could have a displaced Window of Implantation (WOI) and consequently, alterations in their endometrial receptivity. The correction of this displacement can improve the results of the Assisted Reproduction Treatments (ART). The ERA test (Endometrial Receptivity Analysis) evaluates the transcriptomic endometrial profile to determine if the patient's uterus is receptive when the embryo is transferred during an In Vitro Fertilization (IVF) process, and identifies the personalized WOI of the patient. This process is called Personalized Embryo Transfer (pET). The Preimplantation Genetic Test of Aneuploidies or PGT-A (Preimplantation Genetic Testing for Aneuploidy), is currently carried out using Next Generation Sequencing (NGS) and serves to identify chromosomally normal embryos prior to their transfer in an IVF treatment. Aneuploidies are rarely compatible with life or can cause congenital diseases. So, the identification of chromosomally normal embryos, improves the success of reproduction in cases in which infertility is caused by such aneuploidies. Therefore, the aim of this study is to determine, in a randomized and prospective way, the clinical benefit of adding the ERA test to the embryonic aneuploidies test for patients with a PGT-A indication.

This study aims to develop preimplantation genetic testing methods from embryo culture media (cell free). Genetic testing of culture media will be compared to conventional methods based on embryo biopsies.

The purpose of this study is to compare semen parameters with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) when male factor infertility patients abstain from ejaculation more than 48 hours (routine care) or less than 24 hours from the day of the partner's oocyte retrieval. The investigators hypothesize that total motile sperm count will be improved with ejaculatory abstinence (EA) less than 24 hours. Information from this trial could allow investigators to optimize chances for a successful pregnancy in patients who need IVF/ICSI.

This prospective randomized controlled study examines whether the type of glove used (sterile vs clean) for cervical examination to assess progression in labor impacts the rates of intrapartum and/or postpartum infection in patients during labor or induction of labor at term.

Infertility is a life changing disorder, affecting 1 in 7 couples within the UK. Treatment options pose a significant cost burden to both the NHS and patient when NHS-funded treatment options are exhausted. This highlights the need for refinements in clinical management strategies for this patient group. Although there have been advancements in assisted reproductive technologies, the success rates of techniques such as in vitro fertilization (IVF) remain low. Surprisingly, the IVF hormonal regimens used by most assisted conception units fail to take account of patient age, ovarian reserve or cause of infertility when deciding on treatment regimen, with a 'one size fits all' approach to treatment. The investigators propose that age and cause of infertility modify the functions and environment provided by the cells (granulosa cells) that support egg (oocyte) growth and development and understanding these changes will allow for a more personalised approach to IVF treatment regimens. The aim of this study therefore is to recruit female patients undergoing IVF with different causes of infertility and age, and harvest granulosa cells from remaining material (follicular aspirates) generated at the time of egg retrieval. Granulosa cells will be cultured in vitro and cellular functions assessed. The investigators will also recruit female patients with normal fertility undergoing IVF procedure due to other reasons (i.e. egg freezing, diagnostics of genetic diseases on embryos).
