Filter by:The primary aim of the study is to assess the efficacy of letrozole as an ovulation induction agent and to test the hypothesis that letrozole will generate better pregnancy rates with fewer multiple pregnancies and higher live birth rate than the current standard agent, clomifene citrate in anovular infertile women with polycystic ovarian syndrome.
Lifestyle modifications are successfully employed in polycystic ovarian syndrome (PCOS) improving menstrual cycles and fertility. Unfortunately, the compliance over the time is very low. Recently, we have showed a high adherence to structured exercise training (SET) program in women with PCOS. The current study will be aimed to compare the efficacy of the SET program with a diet program on the reproductive function in obese anovulatory infertile PCOS patients.
Clomiphene citrate (CC) and metformin are two effective drugs used to induce ovulation in patients with polycystic ovary syndrome (PCOS), even if it is still unclear which compound between them should be initially administered. The aim of the study will be to compare in a clinical setting the efficacy of CC and metformin as first-line approaches for treating anovulation in infertile PCOS patients.
Purpose of the study is the evaluation of the tolerability (both local and systemic) and the clinical efficacy (in terms oocytes recovered) of subcutaneously versus intramuscularly administered Merional® (IBSA, Lugano – CH) in patients undergoing controlled ovarian hyperstimulation (COH) in an ART programme (IVF).
At the Leuven University Fertility Centre (LUFC) of the Department of Obstetrics and Gynecology of the University Hospitals Leuven, Belgium, a retrospective epidemiological prevalence study based on an electronic search of patient files was performed to determine the prevalence of histologically proven endometriosis in a subset of infertile women with a regular cycle (variation 21 - 35 days), a partner with normal sperm and no previous surgical diagnosis of endometriosis.
The purpose of this study is to determine whether half-dose depot triptorelin are as effective as reduced-dose daily buserelin in the controlled ovarian stimulation for intracytoplasmic sperm injection and embryo transfer
Our goal was to investigate whether early follicular supplementation of the GnRH antagonist to the flexible GnRH antagonist protocol, has a potential to improve IVF-ET clinical results
26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.
On February 2004, a law (n. 40/2004) regulating assisted reproduction techniques (ARTs) was approved in Italy. This law aimed to regulate the treatment of infertility in Italy, contains several restrictions, such as the prohibition to fertilize more than three oocytes and the obligation to transfer simultaneously all embryos obtained. Several evidences showed that the outcome of the in-vitro fertilization (IVF) techniques is strongly correlated with quality of transferred embryos (choosing the right embryos). Furthermore, this prerequisite is actually illegal in Italy, and an optimal oocyte selection can be considered as the only one crucial factor in the determining the outcome of the IVF cycle (choosing the right oocytes). Experimental data have demonstrated that perifollicular blood flow assessment is a good marker of oocyte competence, embryo viability, implantation potential, and subsequent pregnancy rate. The purpose of this study will be to evaluate in a clinical setting whether the assessment of the perifollicular vascularity is a feasible and useful procedure for the selection of oocytes with the best developmental potential in IVF programs when only a limited number of oocytes can be fertilized.
The study tested the hypothesis that a pertubation with a lidocain solution will enhance pregnancy rate.
