Active clinical trials for "Infertility"

GnRH (Gonadotropin-releasing hormone) antagonists in IVF (in vitro fertilization) has been accomplished by several randomized controlled trials compared with conventional GnRH agonist long protocol in polycystic ovary syndrome (PCOS) patients. Moreover, there are debating issues that refer to the timing of GnRH antagonist initiation. The purpose of this study is to investigate the laboratory and clinical priority during ovarian stimulation for IVF in patients with PCOS treated with three different protocols.

The objective of this study was to compare the fertilization rate between the combination of Menopur and Bravelle mixed in the same syringe and Menopur alone, both administered subcutaneously (SC), in subjects undergoing Assisted Reproductive Technology (ART). Additionally the study assessed subjects' ability to mix and store the combination of Menopur and Bravelle and to assess safety of the Menopur and Bravelle combination.

One hundred and twenty women with unexplained infertility were included in the study. Divided randomly into two groups: Group I: (60 patients): (control group) Group II (60 patients): (study group) All the patients received (CC) and human menopausal gonadotropin. On day 5 of the cycle, Doppler examination was performed to all patients. Also on day 5, but only for group (II) patients, local endometrial injury was performed. Doppler studies was repeated, for all our patients, on the same day of prescribing human chorionic gonadotropin

This is a research study on a hormone in women called anti-mullerian hormone (AMH) an indicator of the amount of egg reserve in the ovaries. The research involves a blood draw to determine the AMH level. This knowledge will help the investigators decide a dosage of gonadotropins, the hormones used to stimulate the production of more than one egg for use in an in vitro fertilization (IVF) cycle. The amount of gonadotropin given has to be tailored to each individual participant. The investigators can use information about the participant and the hormone levels to determine this dosage and the chances of becoming pregnant as a result of IVF treatment. The reason the investigators are doing this research is to find out if basing the gonadotropin dosage solely on the participant's AMH level will give the investigators a better result than the previous method based on age and other hormone levels.

In this research study we want to learn more about how effective certain medications are at reducing pain after oocyte (egg) retrieval surgery and how effective they are at reducing the time between the retrieval and discharge from the hospital. We will compare three types of pre-operative medications: intravenous (IV) acetaminophen, oral (PO) acetaminophen, and placebo (no medication), which is the current typical care.

E2 given in late luteal phase can be extended beyond the onset of menses for a period of at least eight days before the start of the stimulation, allowing scheduling of stimulation in order to limit oocytes retrievals during weekends . Administration of corifollitropin alfa, a Follicule stimulating Hormone (FSH) with extended release kinetics, seems particularly interesting for a synchronous recruitment of follicles after homogenization of the cohort. The objective of this study is to evaluate the impact on the response to ovarian stimulation with corifollitropin alfa of E2 scheduling versus no scheduling for women over 38 years, age at which declining of ovarian reserve usually begins. The management of these patients in terms of organization of the center is also evaluated. The scheduling of IVF cycles represents a double benefit. On one hand, to enable a "synchronization" of the follicular cohort for a best response and a higher number of mature oocytes. On the other hand, a more efficient organization for both the center (avoiding retrievals on weekends and public holidays, organize and distribute equally the activity, reduce cost operations) and couples (personal and professional organization).

In-vitro fertilization (IVF) is the treatment of choice for couples with prolonged infertility. The treatment usually involves hormonal stimulation of the ovaries by follicle stimulating hormone (FSH), followed by surgical removal of eggs which are then mixed with sperm in the laboratory to create embryos. The success rates of IVF treatment remain unsatisfactory and are no longer increasing. One of the reasons is an adverse effect of high serum estradiol levels following FSH stimulation on the lining of the uterus. Letrozole is a drug used in the prevention of recurrence of breast cancer because of its action to reduce the intra-ovarian aromatization of androgens to estrogens. It is now increasingly used for ovulation induction and is as safe as clomiphene citrate. Use of letrozole during standard ovarian stimulation for IVF producing adequate numbers of oocytes with physiological levels of estradiol may increase the present success rate of standard IVF treatment. The aim of this randomized study is to compare the live birth rate of FSH alone versus combined FSH and letrozole used for ovarian stimulation in IVF treatment.

Trial to determine the absolute and relative efficacy of two follicular preparation regimens with transdermal testosterone during the cycle (s) prior to the initiation of COS (controlled ovarian stimulation) in patients diagnosed with POR (poor ovarian response) for the increase in the number of mature oocytes recovered.

The purpose of this randomized, two-arm and open label study is to demonstrate that the treatment of a daily dose of 3x10mg dydrogesterone orally is as effective and safe as the daily dose Crinone 8% intravaginal progesterone gel 90 mg for the luteal support in women who are unable to conceive a child and are undergoing IVF. The treatment will start on the day of oocyte retrieval and continue until pregnancy is negative or until week 12 gestation. Patients will be followed during treatment until 30 days after delivery to record any safety and tolerability data of the patient and their newborn (s).

The aim of this study was to evaluate the impact of low dose liraglutide in combination with metformin compared to metformin alone on IVF pregnancy rate (PR) and cumulatively PR (IVF and spontaneous) in infertile obese women with PCOS who had been previously poor responders regarding weight reduction with lifestyle modification and resistant to first line reproductive treatments.
