Active clinical trials for "Infertility"

The present investigation is evaluating a method for improving pregnancy outcome of couples with unexplained infertility. The method utilizes an adjuvant pre-treatment prior to insemination, that is pertubation, i.e. flushing the uterus and fallopian tubes before insemination with a specially developed solution with the aim to increase fertility. The clinical trial is a phase II double blind, randomized, controlled and multi-center trial .

The management of the poor responder patients is very difficult. Currently, there is no any standard treatment for poor responder patients. The study is designed to test a modified GnRHa protocol for poor ovarian response, low dose GnRHa early luteal phase down regulation, compare with GnRHa ultra-short protocol. This is a randomized controlled trial.

Infertility is considered a disease by the World Health Organization and it is increasing worldwide affecting more than 70 million couples. About 50% of the cases are due to male inability to fertilize the oocyte. In the last 40 years, several techniques, known as Assisted Reproduction Technology (ART) have been developed to treat infertility, but the efficiency is still relatively low (around 30%) whereas the remaining 70% attempts again several times, an expensive and emotionally moving treatment. Over 4million of infertility treatments are practiced around the world per year and a 50% increment is expected over the next 6years. Even though ART allows the birth of babies that would be impossible under natural circumstances, it is still necessary to improve the procedures in order to increase treatment efficiency. The success of ART depends, to some extent, on sperm quality. Indeed, the relevance of spermatozoa quality is notorious even beyond fertilization, extending to embryo development and implantation. In this context, it has been developed a new technology that allows the selection of those spermatozoa at their best functional state (Sperm Selection Assay, SSA; Patent approved for USA and Europe, pending for Japan and Argentina). This method is based on the attraction of spermatozoa ready to fertilize the egg, towards a physiological attractant molecule. The SSA may be applied to improve diagnosis and infertility treatment. The investigators hypothesis states that the use of the SSA will improve the number of good-quality embryos which are the ones to be transferred by intracytoplasmic sperm injection (ICSI), providing a healthy embryo development. The protocol involves three experimental groups where the SSA will be used or not, before performing the ICSI: 1)SSA containing the sperm attractant molecule, 2)SSA without the attractant molecule, and 3)without SSA. The patient inclusion criteria involve female factors associated to tubal obstruction and/or endometriosis and male factors associated to sperm disability. Several outcome parameters will be determined, the percentage of fertilization, embryo quality, rate of pregnancy and rate of birth. The study will be carried out in the Universitarian Institute of Reproductive Medicine (IUMER) which has been recently established in a public hospital depending on the National University of Córdoba, offering free high complexity infertility treatment to patients without health insurance or economic support

100 women with infertility classified into 2 groups. Group A: Included 50 women who will be given clomiphene citrate 50mg (clomid) orally 2 times/day from 2rd-7th day of the cycle and sildeaynafil citrate 20mg tab from 7th-11th day of the same cycle orally 3 times/day. Group B: Included 50 women who will be given clomiphene citrate 50mg (clomid) orally 2 times/day from 2rd-7th day of the cycle and placebo tablets from 7th-11th day of the same cycle orally 3 times/day.

A phase 3 multicenter unblinded randomized controlled trial comparing the temporary uterine blood supply occlusion with conventional approach during laparoscopic myomectomy in patients with uterine leiomyoma.

This prospective study evaluates the pregnancy results after laparoscopic endometriosis operation in infertile patients with ERROR (endometrioma related reduction in ovarian reserve)

Hysteroscopy is still considered the gold standard procedure for uterine cavity exploration. Therefore, many specialists have used hysteroscopy as their first-line of routine exam for infertility patients regardless of guidelines. Thus, scheduling the office micro hysteroscopy as one of the routine steps in the fertility workup program has become mandatory before the final diagnosis of unexplained infertility.

To assess the impact of cervical mucus cleansing before embryo transfer and compare two different instruments for this purpose.

Because a large proportion of the embryo's quality is dependent upon the egg, this investigation focuses on treatment of the oocyte during in vitro maturation (IVM). In typical IVF cycles, the egg is recovered when it is mature and ready to be fertilized. However, at this point the oocyte's quality has been set, and cannot be altered. Therefore, to have an impact on oocyte quality the use of in IVM is critical. Development of a successful IVM protocol for clinical use would not only provide an option for women of advanced maternal age, it would also reduce the cost of IVF due to fewer exogenous gonadotropins used for stimulation, and significantly lessen the risk of ovarian hyper-stimulation. The objective of this research study is to evaluate a newly developed oocyte maturation media system for human clinical use in assisted reproductive technology (ART).

Women with history of previous IVF cycle failure will be subjected to a fresh IVF cycle. At the time they will be undergoing embryo transfer, 50 IU of human chorionic gonadotropins diluted in 0.025ml of tissue culture media will be injected intrauterine by embryo transfer catheter 10 minutes before embryo transfer procedure.
