Filter by:The purpose of this study is to compare the efficacy of 1% lidocaine intracervical block to placebo for pain control during the performance of a hysterosalpingogram (HSG). We hypothesized that an intracervical block would decrease pain during a hysterosalpingogram.
Approximately 15 percent of couples experience infertility, yet no abnormalities can be detected in the man or the woman. In a number of couples, their embryos unexpectedly slow down growth or stop growth completely. Some of these situations may be genetically determined. For instance, a portion of cases may be caused by poor egg quality related to genetic or functional deficiencies in heretofore unidentified human maternal effect genes. A model has been developed of such unexplained fertility by creating a mouse line lacking a critical maternal effect gene. (Maternal effect genes produce mRNA or proteins that accumulate in the egg and are required for normal early embryonic development.) This pilot project will test the hypothesis that a similar defect may be a cause of human infertility. Thirty cubic centimeters of blood will be collected from 40 women who have a clinical history consistent with a defective maternal effect gene. DNA from these blood cells will be examined and stored. Some of the blood cells will be treated so that they can be frozen and grown in the laboratory to produce more DNA in the future. If certain mutations are not found, that means that the prevalence of such mutations is less than 10 percent, and investigators may initiate another study with 100 women. If a common mutation is found in at least four patients, the investigators will seek to collect DNA from 150 normal fertile control women for comparison. This project is purely investigational; therefore, findings will not be shared with participants.
We will investigate maternal and embryonic factors in women with recurrent implantation failure, undergoing IVF/ ICSI treatment. Women who have not achieved a pregnancy after three embryo transfer procedures will undergo an endometrial biopsy during the window of implantation in a natural cycle. During the next treatment cycle we will aspirate endometrial secretion and perform a doppler ultrasound investigation of the a. uterina. Moreover, we will investigate the cytokine expression from the transferred embryo from the culture medium.
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.
This study will explore the decision-making experiences of women who are currently pregnant following a period of infertility on whether or not to undergo an invasive prenatal test (IPT) procedure, such as amniocentesis or chorionic villus sampling. Women who become pregnant after infertility often experience heightened anxiety regarding the outcome of the pregnancy. When choosing whether or not to have IPT they are faced with a complex decision, set in the unique context of a pregnancy that they often perceive as exceptionally precarious. Women who are pregnant with their first child after a period of infertility and have made a decision regarding whether or not to undergo IPT may be eligible for this study. Participants complete an online password-protected questionnaire that measures infertility and decision-making variables and explores women's perceptions of the impact of infertility on their IPT decision-making process. The questionnaire covers the following areas: - Subject's demographic information, such as age, marital status, number of children, education, race, ethnicity - Subject's infertility history - Subject's thoughts and feelings about infertility - Subject's thoughts and concerns about other people's (e.g., husband, doctor, other infertile women) opinions about IPT - Subject's decision about whether or not to have IPT and her feelings regarding the decision - The effect of subject's infertility history on her decision to have or not have IPT
This study is being conducted at the University Hospital of Lund University in Malmo, Sweden, in collaboration with the U.S. National Institute of Child Health and Human Development. The study will try to identify genetic causes of impaired sperm production and male infertility. It will focus on the possible role of the MTHFR and CBS genes, which regulate absorption and metabolism of the vitamin, folate in infertility. If the nutritional intake or metabolism of this vitamin is related to male infertility, then this cause of infertility would be potentially curable. Fertile and infertile men between 20 and 45 years of age may be eligible for this study. Criteria include the following: - Fertile men: men whose partners are younger than age 40 and are attending Lund University prenatal clinic; who have fathered one or more pregnancies and who stopped birth control to achieve the present pregnancy; who achieved the present pregnancy in less than 12 months of unprotected intercourse. - Infertile men: men referred to the Scandian Andrology Centre whose infertility is unexplained, whose partners are younger than age 40 and who have had regular sexual intercourse without contraception for at least 12 months without achieving a pregnancy. All participants will have the following tests and procedures: - Complete a questionnaire providing information about their reproductive and medical history and recent dietary history; - Provide blood samples for analysis of red cell folate, plasma folate, plasma homocysteine, plasma B12, and for genetic evaluation; - Provide a semen sample for routine analysis, including volume, sperm concentration, sperm motility, and sperm morphology. In addition, infertile men will undergo a physical examination and review of their medical records.
Multicenter, prospective, randomized, investigator blind, controlled clinical trial. Two parallel groups, one receiving the test drug hMG (hMG-IBSA, IBSA Institut Biochimique sa) and the other the reference drug hMG (Menopur, Ferring Pharmaceuticals, Inc.).
Purpose of the study is the comparative evaluation of the clinical efficacy and of the general tolerability of two different subcutaneous FSH preparations (Fostimon® IBSA Vs Gonal-F® Serono) when administered in patients undergoing ICSI
The purpose of the study is to evaluate the clinical equivalence and the general tolerability of two different subcutaneous hCG preparations (hCG-IBSA, IBSA vs Ovitrelle, Serono) when administered to patients undergoing IVF.
Infertility is a common problem with increased incidence. In-vitro fertilization (IVF) is by far the most commonly used treatment. The success rate of IVF is still low. This study examines the effect of acupuncture on IVF pregnancy rate, as well as possible mechanisms. It is hypothesized that acupuncture can significantly increase the IVF pregnancy rate.
