Active clinical trials for "Infertility"

Basing the investigators study on the evidence that basal serum androgens decrease with age, the investigators hypothesize that women with serum androgens below a certain level could be the population obtaining a benefit of Luteinizing Hormone (LH) supplementation. The objective of the present study is to explore the relationship between basal serum androgen levels and the need of LH for Controlled Ovarian Stimulation (COS) in IVF.

Phase: I pharmacokinetic - pharmacodynamic (PK-PD) study. Main objective: To establish the minimum effective dose of progesterone microspheres suspension, which administered by weekly intramuscular injection, will be able to induce transformation from a proliferative endometrium to a secretory endometrium. Study design: Randomized, controlled, open-label, parallel, dose-response clinical trial. Sites: 1 Subjects: 48 postmenopausal women.

The primary objective of this clinical study is as follows: • To determine the MTD and to assess the safety and tolerability of C31510 administered as a single 4-hour IV infusion (up to nine different dosages) in subjects with solid tumors The secondary objective of this study is as follows: • To evaluate plasma PK and estimate renal elimination of C31510 administered as a single 4-hour IV infusion (up to nine different dosages) in subjects with solid tumors The exploratory objectives of this study are as follows: To evaluate the pharmacodynamic correlates of C31510 activity in plasma and peripheral blood cells To radiographically evaluate the effects of C31510 on tumors. In selected subjects, the effects on vascular permeability will be assessed by digital contrast enhanced (DCE)-magnetic resonance imaging (MRI) To evaluate tumor response (preliminary antitumor activity) after repeat administration of C31510 Long-term safety and tolerability of C31510 after repeat administration

A novel gonadotropin protocol for ovarian stimulation adds low-dose hCG (50- 200 IU) as a source of LH (luteinizing hormone) in the late follicular phase . This regimen reduces the number of small pre-ovulatory follicles which could reduce the risk of OHSS(ovarian hyper stimulation syndrome). Adequate ovarian hormonal levels , oocyte maturation, avoidance of a premature LH surge, and increased pregnancy rate are the other benefits of this regimen. HCG might also affect endometrial function, stimulate endometrial growth and maturation and enhance the endometrial angiogenesis. These effects could extend the angiogenesis. These results could lengthen the implantation Window. Inhibin A is a heterodimer protein and does not begin to increase until just after the increase in oestradiol in the late follicular phase, suggesting secretion by the dominant follicle. Inhibin A secretion is regulated by LH and is associated with paracrine/autocrine action on oocyte maturation. Moreover, it is related to follicular development and size, serving as a marker of follicular maturation after IVF cycles .However, the role of hCG supplementation during COH (controlled ovarian hyperstimulation)is still a matter of debate and more studies is needed. Thus, the objective of this trial was to investigate whether LH activity in the form of low dose hCG in GnRH (Gonadotropin releasing hormone)antagonist cycles would improve the quality of oocytes, level of inhibin A and endometrial vascularity.

This trial investigates the effects of FE 999049 compared to GONAL-F.

This study is a randomized, double blind, controlled clinical trials assess the efficacy of the ginger oral treatment on sperm DNA fragmentation, sperm parameters and male hormones.

This is a Phase 3, randomized, controlled, single-blind, multicenter, parallel-arm trial to assess the safety and efficacy of Pergoveris® (recombinant human follicle stimulating hormone [r-hFSH]/recombinant human luteinising hormone [r-hLH]) and GONAL-f® for multifollicular development as part of an assisted reproductive technology (ART) treatment cycle in poor ovarian responders, as aligned with the 2011 Consensus Meeting of the European Society of Human Reproduction and Embryology (ESHRE) criteria.

The aim of this randomized controlled trial is to compare the efficacy of ultrasound guided aspiration of hydrosalpingeal fluid with salpingectomy in the management patients with ultrasound visible hydrosalpinges undergoing IVF-ET.

Purpose:The aim of this project is to prospectively determine whether a single dose of GnRH-agonist administered at the time of implantation increases or not the reproductive outcome in patients undergoing in vitro fertilization ( IVF)/ intracytoplasmatic sperm injection(ICSI) triggered by a GnRH-agonist followed by a small bolus of human chorionic gonadotropin (hCG 1500 IU) the day of oocyte retrieval. Acronyms: GnRH: gonadotropin-releasing hormone FSH: follicle stimulating hormone LH: luteinizing hormone HCG:human chorionic gonadotropin IVF:In vitro fertilization ICSI:intracytoplasmatic sperm injection OHSS:ovarian hyperstimulation syndrome OMEGA: oocyte maturation employing GnRH-agonist OPU: ovum pick up NaCl: sodium chloride

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.
