Active clinical trials for "Infertility"

This non-interventional study (NIS) is planned to examine the consistency of the dose recommended by the doctor for the first stimulation day with the dose recommended by the CONSORT calculator.

The development of recombinant DNA technology, culminated in the introduction of the first recombinant human follicle stimulating hormone (r hFSH), Gonal-f, which further developed to become Gonal-f Filled-by-Mass (FbM) pen has been used in the fertility treatment since many years. It has been found that subjects using the pen found it less stressful, easier to use and more convenient than a conventional syringe and would recommend the prefilled pen to another woman considering gonadotropin treatment. However, the use of the Gonal-f (FbM) pen between Serbian subjects is on a very low level though the Gonal f vials with the 75 IU of follitropin alfa have been present in Serbian market since 2003. On the contrary from the clinical practice in European countries, Serbian subjects usually receive daily dose of injectable gonadotropins at the IVF clinics or by partner/family member. This open-label, multicentric, observational non-interventional study is designed with the aim to know the reason of Serbian subjects not injecting themselves with Gonal f and the quality of life (QoL) of Serbian women/couples with the infertility problem.

In order to improve success rate by assisted reproductive techniques new techniques are being developed for selection of the embryo with best chance of implantation, establishement of pregnancy and subsequent delivery.The present study is based upon the hypothesis that time-lapse (frequent imaging) may give information about important steps in embryonic development, which could help to optimize selection of embryo(s) for treatment in IVF. The present study evaluates the outcome of conventional embryo culture with culture in a specially developed incubator equipped with a time-lapse system (Embryoscope). Embryos from 50 IVF cycles (400 embryos) will be randomised to either conventional incubation or to culture in the Embryoscope. Embryos will be cultured for five days to the blastocyst stage. The primary endpoint is fraction of embryos developed to the four cell stage.

To identify adverse effects of ovulation drugs on pregnancy, including pregnancy loss, fetal teratology and dysmorphology, and infant development up to age 3.

To assess the effectiveness of a protocol of ovarian hyperstimulation with urinary gonadotrophins, to achieve clinical pregnancy in females undergoing IVF. Study hypothesis: to assess the effectiveness of a protocol of urinary gonadotrophins

With the development of the recombinant gonadotrophins, the use of human source proteins for the production of hormones has become unnecessary. These proteins, which are found in urinary preparations, have been thought to cause the local, post-injection adverse events (AEs) in some subjects. There has been a demand by physicians for an alternative to urinary products for treatment. Due to allergies to urinary products, or other personal reasons, subjects were not able or willing to be treated with proteins of human origin. This study allowed subjects to be treated with the recombinant human chorionic gonadotropin (r hCG) (free of urinary proteins), which otherwise would not be possible. The study sponsor used this opportunity to collect additional safety data on the new recombinant product, (Ovidrel, r-hCG).

Many women undergoing in vitro fertilization (IVF) ask their doctor if there are any behaviors they should avoid, or any behaviors they should emphasize during their IVF cycle. This study examines the effects of health habits surrounding exercise, smoking, alcohol, sleep, caffeine, herbal medications, acupuncture, and diet on pregnancy rates during IVF cycles. The purpose of this study is to determine if lifestyle behaviors have a significant impact on pregnancy rates during treatment with IVF. This is an observational study conducted at a private academically-affiliated infertility clinic and includes 118 women ages 44 and below scheduled to undergo IVF treatment. All subjects were asked to complete a health history survey at the time of enrollment and a daily survey during each day of their IVF cycle. The primary outcome is clinical pregnancy rate.

The object of this study is to determine the benefit of follicular flushing with a double channel needle in a poor responder population for a maximum number of oocytes to be retrieved. The investigators compare two methods of oocyte retrieval with or without flushing. 220 patients undergoing an in vitro fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) have to be included. All patients with less than 5 follicles of 14 mm and more the day of ovulation induction will be included, following a randomized protocol in two groups, Group A: Oocyte retrieval is performed with a single lumen aspiration needle 17G. Group B: Oocyte retrieval is performed with a double lumen aspiration needle 17G. all follicles are flushed with flushing solution in addition to direct aspiration of the follicular fluid, 20CC of flushing medium is provided for all the procedure and flushing medium is collected separately from direct fluid aspiration in order to follow up each oocyte one by one. First criterion of our comparison is the number of oocyte retrieved. Second criteria are: oocyte quality, fertilization rate, number and quality of embryos obtained, clinical pregnancy rate. In Group B the investigators will compare two subgroups: oocytes collected in flush medium and oocytes from direct follicle fluid. Then the investigators will know the capability of oocyte collected after follicular flushing to be fertilized and to increase the success chance of pregnancy for poor responder patients.

The purpose of this study is to prospectively define a set of data suitable for developing models of pregnancy viability. Those models will be based on serum hCG concentration measured during the peri-implantation period in patients that received fresh embryo transfer and those that received transfer of frozen-thawed embryos, and to compare and contrast these models. This may reveal insights into differences between these types of IVF cycles.

To assess the relations of infertility causes and treatment to cancer risk, we will conduct a retrospective cohort study of approximately 12,000 women evaluated for infertility between 1965-1988. These women will be ascertained from several large infertility clinics and private practices in various geographic locations in the United States: Boston, Chicago, Detroit, New York, and Palo Alto. These practices were selected on the basis of their having large number of patients who received ovulation stimulating drugs many years in the distant past. Abstractors reviewed clinic medical records to identify eligible study participants and abstract data needed to classify causes of infertility and document therapies employed. Using a variety of tracing sources (including the National Death Index, credit bureaus, and postmasters), the vital status and location of the study subjects were determined. Subjects who were traced and identified as alive are being sent a detailed questionnaire that requests information on their health status as well as on a number of lifestyle practices. For subjects who report a cancer, medical verification is being sought from the diagnosing physicians and/or facilities. Death certificates are being sought for deceased subjects.
