Active clinical trials for "Infertility"

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.

This prospective cohort study of 400 lead exposed and 400 non-lead exposed women and their husbands assesses endocrine dysfunction and adverse reproductive outcomes. Residing in two study areas in Shenyang, China, the women are married, 20 and 34 years of age, never smokers, have obtained permission to have a child, and have attempted to become pregnant over the course of the study. Lead exposure is defined by lead levels in blood samples collected at the baseline survey (both women and their husbands), first and second trimesters, and at delivery (both maternal and cord blood). Endocrine dysfunction is monitored by urinary hormone metabolites including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrone conjugates (E1C), and pregnanediol-3-glucuronide (PdG). Reproductive endpoints include menstrual disturbance, time to conception, spontaneous abortion, preterm delivery, and low birth weight.

No therapy for infertile patients with premature ovarian failure has been proven effective. Some anecdotal reports have suggested that high dose, long term prednisone (steroid) therapy may be useful in treating autoimmune ovarian failure. However, prednisone, when used in high-doses for long periods of time has substantial side effects, including aseptic necrosis of bone where portions of bone die without the presence of infection and are surrounded by healthy tissue. Aseptic necrosis of bone often requires major surgical treatment. Even with this known level of risk, patients with premature ovarian failure are being treated based on this anecdotal evidence. This study will test the hypothesis that a lower risk therapy (alternate-day, lower dose, shorter-term prednisone) will cause a remission of autoimmune ovarian failure. There is no reliable blood test to identify patients who have premature ovarian failure. Therefore, all patients must undergo a laparoscopic ovarian biopsy to confirm the presence of an auto immune reaction in the ovaries (autoimmune oophoritis). Laparoscopy is a surgical procedure that allows doctors to explore the abdomen using a camera-like device called a laparoscope. The procedure has been used clinically by some reproductive endocrinologists to identify patients with premature ovarian failure who have an autoimmune mechanism for the disorder. The treatment will be deemed successful based on the return of ovulation as determined by weekly serum progesterone levels.

25 to 50% of endometriotic patients are infertile and use medically assisted procreation. In general, the assessment of pain in medically assisted procreation is very little studied. Pain assessment studies in endometriotic patients remain limited to a quantitative assessment of pain symptomatology, without contextualization of painful manifestations. The primary objective of our study is the qualitative and contextualized assessment of pain during In Vitro Fertilization (IVF) protocol in endometriotic and non-endometriotic patients. The secondary objectives of our study are the quantitative study of pain, the measurement of the impact of personal efficiency on painful symptomatology, evaluation of depression, the results of IVF (implantation, pregnancy and live birth rates), and compare pain between endometriotic or non-endometriotic patients and between primary infertility and secondary infertility. According to the results obtained in this study, therapeutic strategies for the management of pain could be proposed, with the aim of improving the quality of life and the results of IVF in these patients.

The impact evaluation of ovarian hyperstimulation on coagulation and fibrinolysis in infertile women. Comparative analysis between different ovarian stimulation protocols on thrombin formation and efficiency of fibrinolysis in women diagnosed with infertility.
