Active clinical trials for "Infertility"

Tubal ligation is an everyday procedure for permanent female sterilization. It is usually performed after a vaginal delivery. Minilaparotomy is generally performed by doing small incision at infraumbilical area. This minimal access surgery requires adequate operative field exposure. Bowel interference, which obscures visualization of the operative field has been recognized as one of the major obstacles during this procedure. We found problems while doing surgery in small space and one of them is bowel interferance which obscures vision. This could lead to prolonged operation and complications. Simethicone is an antifoaming agent that use in bowel preparation prior to various procedures including laparoscopy, colonoscopy, endoscopy, and open major abdominal operations. Simethicone is proven to break the bubble and reduce intraluminal gas. This effect could result in reduction of bowel dilatation that interfere with the proper identification of the adnexal area. Benefit of taking simethicone prior to do minilaparotomy for tubal resection has not been examined. Objectives: To examine the effect of simethicone on reducing bowel interference during minilaparotomy for tubal resection. Design: A randomized controlled trial in women, age 20-45 years, undergoing postpartum sterilization after vaginal delivery at Faculty of Medicine, Chiang Mai University hospital. The participants will be randomly assigned into one of two study groups: intervention (taking simethicone) and control (not taking simethicone). For the intervention group, each woman will take simethicone (80 mg) 2 tablet chewing with water 50 ml at 2-8 hours before surgery. Fasting at least 6 hours before surgery. For the control group, the women will receive the same standard perioperative care without taking simethicone. The primary outcome measure will be surgeon-rated operative difficulty score, which is a visual analog scale based on assess from exposure of to the operative field in visual analog scale by surgeon. The secondary outcome will be operative time and incidence of intraoperative and postoperative complications.

Conventionally, ICSI was initially developed and has been shown to be an effective treatment for male factor infertility. It is increasingly being used for patients without a male factor diagnosis, despite the lack of clinical evidence to support its use. Moreover, ICSI is an invasive and expensive procedure. This multi-center, randomized, controlled, parallel-group trial will be conducted to compare the effectiveness of ICSI versus conventional IVF in infertile couples scheduled for IVF treatment, in whom the male partner has normal sperm.

In mammals, uterine environment is at low oxygen concentration (2-8% O2). Thus, human embryo culture under low O2 tension (5%) is now recommended by European Society of Human Reproduction and Embryology (ESHRE) revised guidelines for good practices in in vitro fertilization (IVF) labs. Indeed, hypoxia seems to improve embryo quality at cleavage and blastocyst stages, presumably by reducing damages of oxidative stress (OS). Nevertheless, recent meta-analyses concluded only with a low evidence to a superiority of hypoxia on IVF/ICSI outcomes. Furthermore, a study on mouse embryos suggested a negative impact of OS only at cleavage stage. The aim of the present prospective randomized study was to investigate this hypothesis for the first time in human embryos.

The aim of this study is to evaluate the effect of treatment of vitamin D deficiency (through vitamin D supplementation for 8 weeks before the start of In-vitro fertilization (IVF) on the success of IVF cycles.

Despite these revolutionary changes in the laboratory, little has changed with the process of embryo transfer (ET). A study to prospectively evaluate the role of cervical mucus removal prior to embryo transfer on pregnancy rates in ART will be undertaken.

To determine the significance of systemic RANKL inhibition for male reproduction, conducting a clinical controlled randomized double blinded intervention study on infertile men, to investigating whether Denosumab (Prolia) can increase semen quality and to investigate what subgroup of infertile men that might benefit from treatment.

Until now very little information exists regarding the early luteal serum progesterone profile after Human chorionic gonadotropin (hCG) trigger. This pilot study will help characterize the serum progesterone, 17-hydroxyprogesterone profiles in IVF patients and correlate progesterone, 17-Hydroxyprogesterone levels to ovarian follicles obtained after stimulation with exogenous gonadotropins.

study the effect of aromataze inhibitor induction together with short stimulation protocol by gonadotrphin releasing hormon antagonist in cases that expected to be poor responder before ICSI

This is a pilot study of a novel protocol for preparation of the endometrium for frozen/thawed embryo transfer whereby estrogen is not administered during the proliferative phase and progesterone is administered through vaginal suppositories in accordance with endometrial thickness only, disregarding the day of ovulation. Progesterone supplementation commences once the endometrium is at least 7 mm, a follicle is demonstrated on TVS, and ovulation has not yet taken place. The day of ET is scheduled according to the unit's working days and progesterone suppositories are commenced 48 hours before the scheduled embryo transfer.

The present study is designed as a pilot study with 50 patients in each group. Data collection form will be filled by the researcher who does not know the type of intervention in each group
