Active clinical trials for "Infertility"

The aim of this study is to evaluate if Myo-inositol, N-Acetyl-Cysteine plus a cocktail of antioxidants could be able to increase spermatozoa parameters and reduce semen hyper-viscosity

The aim of this study is to investigate that the efficacy of the endometrial injury before IVF in recurrent implantation failure patients.

In the early stage, our team found that traditional Chinese medicine (TCM) intervention aimed at Nourishing kidney and regulating blood circulation in vitro fertilization and embryo transfer(IVF-ET) can improve the clinical pregnancy rate. In order to further study the role of TCM in improving the pregnancy outcome of IVF-ET in infertility due to decreased ovarian reserve (DOR). A randomized controlled clinical trial was used in this study. 200 infertile patients with DOR were randomly divided into two groups. The control group was treated with conventional modern medicine, and the treatment group was treated with traditional Chinese herbs on the basis of conventional modern medicine. The intervention started from the 5th day of the first menstrual cycles after enrollment and lasted for three months before IVF-ET. After the transplantation, the TCM treatment continues for 14 days. The number of oocytes, antral follicles, anti-Mullerian hormone(AMH), serum follicle-stimulating hormone(FSH), and clinical pregnancy rate will be observed to evaluate the effect of traditional Chinese medicine on the improvement of ovarian function, pregnancy outcome, and fertility of DOR patients.

Investigators will evaluate and compare the efficacy of Sitagliptin/Metformin to metformin and sitagliptin on gdf9 and bmp15 gene expression on PCOS patients undergoing intracytoplasmic sperm injection(ICSI).

There is an increased prevalence of high Body mass index (BMI) all over the world.High BMI is shown to have an impact on the female reproductive system.It can contribute to both ovulatory and anovulatory subfertility. Clomiphene citrate and Letrozole have been used for treatment of infertility.Both are used for induction of ovulation. Clomiphene citrate is an estrogen receptor antagonist .It increases serum FSH and it has its limitation due to his antiestrogenic effect,it has an ovulation rate 70-80% but pregnancy rate is only 22% because of its anti-estrogenic effect on endometrium and poor cervical mucus (Legro RS et al.,2007) Letrozole is an aromatase inhibitor which inhibits the production of estrogen, which influences the action of the brain's hypothalamus and pituitary on the functioning of the ovaries by increasing FSH.Due to the antiestrogenic effect of clomiphene citrate,Letrozole can be used as an alternative. The investigators are comparing the effect of both medications on the outcome of the induction of ovulation in women with high BMI.

Microfluidic chips are one of the methods of sperm separation to eliminate DNA fragmentation in sperm. It is thought that the separation of sperm by centrifugation in the classical gradient density (Percoll) method used in sperm separation in IVF and IUI cycles leads to the increase of reactive oxygen radicals in sperm and this leads to sperm DNA fragmentation. Studies comparing Percoll and microfluidic chip method in terms of sperm, embryo quality and pregnancy rates are limited. In this context, it is aimed to investigate the effect of Percoll or Microfluidic Chip Technology on the quality of sperms and embryos obtained with these sperms and their pregnancy rates prospectively.

Intra-uterine insemination (IUI), generally in combination with ovarian stimulation, is one of the most commonly used treatments for infertility. Accurate timing of insemination, in order to coincide with ovulation, has an important impact on the success rate. Optimal timing of insemination is achieved either by monitoring follicular growth through serial ultrasound measurements followed by the administration of human chorionic gonadotropin (hCG) or by the detection of urinary luteinizing hormone (LH). However in cycles where follicular growth is monitored there is a possibility of premature LH rise before the administration of hCG, which may affect the outcome of the treatment. The goal of the study is to determine if adding the testing of urine LH in conjunction with ultrasound monitoring leads to an increase in pregnancy rates in IUI cycles when compared to ultrasound monitoring alone.

This is a single center, prospective, observational study on the use of Gonal-f in controlled ovarian hyperstimulation (COH) in subjects undergoing ovulation induction/ intrauterine insemination (OI/IUI) therapy across Taiwan. It has been observed in the previous studies that COH with follicle stimulating hormone (FSH) is considered as one of the positive predictors of an ongoing pregnancy. Many studies in the past have tried to predict the FSH threshold, defined as the FSH dose on the day when a follicle is >10 mm in diameter, but no studies have been conducted to date to determine the predictive factors for a monofollicular development after COH in IUI cycles. Monofollicular growth contributes significantly to the reduction of multiple pregnancies and thus minimize the risks associated with such pregnancies. This study would provide preliminary data on the factors associated with a monofollicular development in Gonal-f treated cycles using a low dose step-up regimen.

Literature suggests that GnRH antagonists are comparatively more often used in cycles which have an unfavorable prior prognosis, and this protocol is an ideal one for poor responder patients. Up to now, however not enough prospectives have been published to prove any beneficial effect of antagonists on the first cycle assisted reproductive technique. This prospective study will do to evaluate the efficacy of gonadotropin releasing hormone antagonist in comparison with the standard long protocol in the first cycle of ART. The investigators will randomize 160 patients undergoing ART for the first time . Group 1 (n=80) was stimulate with a standard long protocol and group 2 (n=80) stimulated with GnRH antagonist and then result of ART compare in two group .

Primary objective: To evaluate the efficacy in terms of oocyte retrieval number of rLH supplement in women with hyporesponse to rFSH after pituitary downregulation. Secondary objective: To further explore the efficacy of rLH supplement in women with hyporesponse to rFSH after pituitary downregulation To evaluate the safety of rLH supplementation in hyporesponse women
