Active clinical trials for "Infertility"

This study is for patients undergoing In Vitro Fertilization (IVF). The investigators are studying the best way to control pain during the egg retrieval process. The egg retrieval involves passing a needle under ultrasound guidance through the vagina into the ovaries to remove eggs that are to be later fertilized. Patients often report this as very uncomfortable. Different fertility clinics across the country use different methods of pain control. All clinics will use intravenous medication to control pain, while some may or may not use local anaesthetic (freezing) in the vagina. Our goal is to find the best way to control pain. Since local anaesthetic injection involves multiple needle punctures and may be painful, the investigators are unsure if local anaesthetic is necessary in addition to the intravenous pain medication. The investigators will conduct a randomized trial where all patients will receive intravenous pain medication, but some will receive local anaesthetic injection and some will receive placebo injection. Patients will be asked to complete a questionnaire on their pain experience after oocyte retrieval. The investigators will then analyze the data and determine whether local anaesthetic actually improves pain when patients are already receiving intravenous pain medications. Through our study, the investigators aim to improve the pain experience of all women undergoing IVF in the future.

open label, active-controlled, randomized, parallel group, comparative study.

The aim of the current study was the determination of the recommended standard treatment dose of FSH-GEX(TM) in women undergoing intracytoplasmic sperm injection (ICSI) treatment as assessed by follicle growth.

To evaluate the effect of pentoxifylline used in preparation of semen samples that will be used for ICSI in infertile men complaining of mild and moderate asthenozoospermia (i.e. cases which does not need motility enhancement prior to ICSI) in comparison to semen samples without pentoxifylline preparation on the outcome of ICSI.

Female inability to conceive a child. The purpose of this randomized, two-arm and double blind, double dummy study is to demonstrate that the treatment of a daily dose of 3x10mg dydrogesterone orally is as effective and safe as the daily dose of 3x200 mg micronized progesterone capsules administered intravaginally for the luteal support in patients 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 after treatment until 30 days after delivery to record any safety and tolerability data of the patient and their newborn(s).

In assisted reproductive technology (ART) semen needs to be processed. Commonly used methods rely on physical properties of the spermatozoa, such as the swim-up methods and density gradient centrifugation. It is now known that current processing of spermatozoa does not prevent the admixture of spermatozoa with damaged genetic material. The latter have a negative impact on the outcome of ART. The investigators developed a new method for the processing of spermatozoa with intact genetic material based on flow cytometry and sorting (FACS) and on staining using a deye, YoPro. The investigators aim at examining the effect of this novel method of sperm sorting on the outcome of ART.

The purpose of this study is to determine if growth hormone given 4 weeks before as well as during a cycle of in vitro fertilization will improve outcomes in women who have had previous failure with IVF treatment cycles using high doses of follicle stimulating medications and had a poor response (less than 6 follicles).

Primary Aim Evaluate whether human embryo exposure to physiologic levels of oxygen during culture improves the percentage of women who deliver a baby following in vitro fertilization and embryo transfer. Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves live birth rate in clinical In Vitro Fertilization Embryo Transfer (IVF-ET). Secondary Aims Evaluate whether human embryo exposure to physiologic levels of oxygen during culture during in vitro fertilization and embryo transfer improves embryo cleavage improves clinical pregnancy rate reduces multiple pregnancy rate reduces miscarriage rate Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves embryo cleavage and clinical pregnancy rates and reduces miscarriage rates in clinical IVF-ET.

The purpose of this study is to assess the effect of luteal phase supplement (LPS) on pregnancy rate in IUI cycles stimulated with clomiphene citrate.

This study was conceived in order to explain what the investigators previously observed suggesting that lisinopril, a drug normally used to treat patients with high blood pressure and heart failure, may be effective in treating infertile men with low sperm count. The investigators hypothesized, therefore, that the drug will not only improve sperm quantity and quality but also increase the fertility in such patients. The investigators first of all reviewed the results of previously published investigations and found out that there was only a few previous studies done in humans.with this class of drugs. Besides, the methods used in conducting most of those studies have been so faulted that the results cannot be trusted to be showing the true picture. The investigators looked at the various faults pointed out with respect to the their design and conduct and took care of them while designing the investigators own study. This was an attempt to provide more credible answers to the question of whether lisinopril, and possibly other drugs of similar mode of action, can be useful in rectifying the problem of infertility caused by low sperm count and , if so, whether it will be safe to use it in people who do not have high blood pressure or heart failure. In order to achieve this the investigators studied 33 patients with sperm of low cell concentration, low percentage of motile cells and high percentage of abnormal cells from no known cause. The patients were randomly allocated to receive either lisinopril 2.5mg daily (17 patients) or daily placebo (16 patients)and their sperm characteristics were examined at intervals, starting from the beginning of the study until when it ended 282 weeks later. The patients were also monitored for adverse events throughout the period. The data form all the patients that took part in the random allocation of treatments at the beginning of the study were included in the analysis that followed, irrespective of whether they completed the study or not.
