Filter by:This trial investigates the effects of several doses of FE 999049 in women undergoing IVF/ICSI (in-vitro fertilisation/intracytoplasmic sperm injection) treatment.
Progesterone levels measured in blood/serum of patients on the day of ovulation induction following controlled ovarian stimulation for in vitro fertilization may be associated with pregnancy outcome. The hypothesis is that higher progesterone levels are associated with lower implantation rates due to changes in the endometrial receptivity.
The purpose of this study is to determine if pretreatment with Estrogen can assist in the planning and programming of In Vitro Fertilization treatments.
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.
This prospective study collected safety information from more than 600 participants treated with Pergoveris®. During the Post-Marketing Surveillance (PMS) period, data about the participant's background, participant's medical history, Pergoveris® indication, prior infertility medication, Pergoveris® treatment status, concomitant drugs, all adverse events (regardless of the causal relationship to Pergoveris®) and efficacy (follicular growth and clinical pregnancy) were collected for study purposes.The post marketing surveillance was based on all cases treated with Pergoveris®.
Endometrial scratching in luteal phase of a spontaneous menstrual cycle may increase pregnancy rate in women with unexplained infertility.
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.
This observational study will examine the safety and efficacy profile of Elonva (corifollitropin alfa) when administered in Korean women undergoing controlled ovarian stimulation (COS) in combination with a gonadotropin-releasing hormone (GnRH) antagonist for the development of multiple follicles in an assisted reproductive technology (ART) program.
This study seeks to compare the pregnancy and delivery rates of patients who undergo a single embryo transfer, when the embryo has been tested and determined to be chromosomally normal, with pregnancy and delivery rates of patients who undergo a two (2) embryo transfer of untested embryos.
BACKGROUND: One couple out of 6 consults for infertility during their sexual life. In 60% of cases a male factor is associated or is the main infertility factor. Inflammatory Syndrome (IS), characterized by the presence of a leukocytospermia is found in 12% of the cases. Leukocyte degranulation causes oxidative stress (OS) through the formation of free radicals attacking the sperm cell functions. HYPOTHESIS: To establish the responsibility of the IS, and OS, in chronicle inflammatory male infertility, the investigators hypothesize that its treatment (as well as its possible cause) must restore or improve the fertilizing capacity of patients sperm. METHODS: This prospective randomized study will test the response to the treatment. The investigators shall measure cellular degradation products due to the OS, thereby certifying that it does have a deleterious effect on sperm cell. Seminal biochemistry will also assess the impact of the syndrome on the genital tract glands and follow its evolution. The patients will be included in the study as soon as the leukocytospermia will be > 0,5*106/ml or as soon as the elastase will be > 500 ng/mL. The examinations will be performed using flow cytometry, CASA (Computer Assisted Semen Analysis). The analysis of sperm morphology will be centralized. Primary endpoint will be a reduction in the percentage of 8OH-dG below 35 %. We anticipate that it should arrive to 20 % of the patients included in the arm treatment by corticosteroid therapy. All in all will thus be needed 50 patients in the group placebo and 50 in the group treated. Secondary endpoint the improvement of the spermatic parameters and the reduction of the fragmentation of the DNA of sperm cells to the treated subjects. All these biological markers will be evaluated 6 month after the treatment: - Fragmentation of the spermatic DNA below 37 % during the follow-up in 6 months - Leukocytospermia and elastase - Seminal biochemistry - Other markers of the inflammatory syndrome and oxidative stress (protein carbonyl, 8OHd-Guanosine) - Possibly the radiological examinations (Ultrasound and MRI of the genital tract) In addition it would allow us to propose a policy of prevention towards acquired post-infectious male infertility.
