Active clinical trials for "Infertility"

The purpose of this prospective, randomized study, was to determine if neck and shoulder massage performed within 15 minutes of semen sample collection will increase the semen volume, and therefore increase the total motile sperm available for insemination as a result of decreased stress.

The aim of this study is to determine whether different needle gauges influences the quality of the aspirated oocytes during in-vivo fertilization (IVF).

The purpose of this study is to determine whether minimal ovarian stimulation for in vitro fertilization is superior to high dose stimulation. Number of mature eggs, number of embryos as well as pregnancy rates will be compared.

Artificial oocyte activation with strontium chloride or calcium ionophore improves fertilization, embryo quality, pregnancy and delivery rate in women who showed complete fertilization failure or low fertilization rates

Preimplantation Genetic Screening (PGS) is used for the selection of chromosomally normal embryos before the transfer in IVF treatments in many cases. There is great debate in the scientific community as to whether this is an efficient practice in patients of different prognosis. This prospective and randomized study seeks to study the results of chromosomal diagnosis using the new Comparative Genomic hybridization (CGH) arrays technique by practicing Preimplantation Genetic Screening (PGS) in day three biopsy on one arm of the study and not on the other arm in order to compare the results. The investigators will study the ongoing pregnancy rate of each oocyte retrieval and the ongoing implantation rate with Day 5 embryos (blastocysts) in IVF/ intracytoplasmic sperm injection (ICSI) treatments of embryos from two different groups of patients: Advanced Age Female Patients (38 - 41 years of age) and Male severe factor (≥2 million spermatozoids/ml.).

Human decidual tissue appears to play an important role not only in nurturing the implanted embryos, but also in preventing its rejection by the maternal immune system. Insight into the maternal immunologic modulations during implantation is our main research interests. Our previous studies have shown that most lymphocytes in deciduae are natural killer cells. However, their phenotype is CD16-CD56+CD3-, which is different from that of peripheral natural killer cells. More importantly their cytotoxic activity is decreased and they can't attack the cytotrophoblasts. All of these contributes to no rejection developing at the fetomaternal interface and are related to success of pregnancy. In 1994, a new cytokine IL-15 was first discovered, which could act on the IL-15 and IL-2 receptors to stimulate the activation and propagation of the lymphocytes. Let us want to study the critical role of IL-15 in the endometrial lymphocytes. In this study, we try to analyze the distribution of IL-15 and its receptor in deciduae. We will clarify whether the IL-15 receptor exists on the decidual natural killer cells and it is regulated by sexual hormones or not and whether their cytotoxic activity will change after IL-15 action. Furthermore, we will demonstrated whether the IL-15 receptor exists on the embryo cells and IL-15 might improve the quality of the embryo. We also design a co-culture system of the embryo and autologous endometrial cells to improve the success rate of in vitro fertilization.

This study is aimed to evaluate the use of a closed device for storage of vitrified oocytes.

In polycystic ovary syndrome (PCOS) patients, both in vitro maturation (IVM) and intra-cytoplasmic sperm injection (ICSI) are indicated as optional treatments. Although recently ICSI techniques have been reported as more successful the IVM in achieving pregnancy, they have also become much more expensive for the couples involved. Whilst most high-income countries offer Assisted Reproductive Technology (ART) procedures fully or partially paid by the government, the patients in low or middle-income countries have to cover self-fund infertility treatments. With limited resource, a study conducting based on the prevalence - based cost - effectiveness analysis is necessary for health managers, policy makers and especially to assist patients' decision making in these countries. However, there are still limited published studies that have evaluated the cost-effectiveness of these strategies are available in the literature. This study is conducted based on the prevalence - based cost - effectiveness analysis from the patient's perspective. Activity - based costing method is used to cost in all levels of the healthcare system, which the patients have to pay directly or indirectly. It also analyses incremental cost - effectiveness to evaluate the cost - effectiveness of IVM and ICSI in PCOS women.

Patients & Methods: Eighty infertile women were randomly categorized into: Group EF (n=40) had EF after oocyte retrieval and Control group (n=40) did not have EF. All women were subjecte to the standard down-regulation regimen followed by controlled ovarian hyper stimulation . Oocytes were retrieved 34-36 h after hCG administration and aspirated FF was collected and centrifuged at 600 rpm for 10 min and 5-ml sample of supernatant was obtained for ELISA estimation of tumor necrosis factor-α (TNF-α), granulocyte colony-stimulating factor (G-CSF), leptin and anti-Mullerian Hormone (AMH) levels in both groups. The remaining amount was used for EF in EF group and was discarded in control group. Pregnancy was diagnosed by measurement of β-HCG level and confirmed by transvaginal sonography as clinical pregnancy

The aim in this study is to determine whether there is a relationship between Thiol / Disulphide levels in primary infertile patients and comparing them with infertile patients and the control group. For this purpose, 41 women followed up with the diagnosis of primary infertility in Siirt Training and Research Hospital between November 2022 and January 2023 will be included in the study. The same number of (n:41) non-infertile control women will be included. Age, pregnancy history and medical history of both groups will be recorded. FSH, LH, E2, TSH, and prolactin levels taken routinely in these patients will be examined. Thiol/disulphide levels in the blood will be checked by taking whole blood from these patients. In the light of the information thus obtained, the investigator plan to determine whether there is a relationship between oxidant/antioxidant balance in primary infertile patients.
