Filter by:Trial to determine the absolute and relative efficacy of two follicular preparation regimens with transdermal testosterone during the cycle (s) prior to the initiation of COS (controlled ovarian stimulation) in patients diagnosed with POR (poor ovarian response) for the increase in the number of mature oocytes recovered.
The use of Intracytoplasmic sperm injection (ICSI) has increased in the last decades regardless of the cause of infertility. Despite the increased use there is no clear evidence that ICIS is more effective than conventional in vitro fertilization (IVF) for non-male factor infertility. The investigators therefore aim to perform a prospective randomized controlled study to compare between ICSI and conventional IVF in women between 39 to 44 years of age with non-male factor infertility.
The investigators aim to examine the endometrium with state of the art sequencing techniques to investigate the endometrial microbiota. The endometrial microbiota has been perceived to be sterile, however, this seems incorrect from recent studies. Thus, the primary outcome is to compare the rate of ascending infection from the semen to the vagina to the endometrium and to investigate which bacteria are capable of inhabiting these environments. Furthermore, cervical mucus will be obtained in order to test for immunological, microbiological and mechanical properties that may be involved in ascending infection. Finally, the study aim to characterize the temporal changes in the vaginal microbiota during estrogenic treatment with Estrofem® or Vivelle Dot (R) for preparation of the endometrium prior to embryo transfer.
The aim of this study was to evaluate the impact of low dose liraglutide in combination with metformin compared to metformin alone on IVF pregnancy rate (PR) and cumulatively PR (IVF and spontaneous) in infertile obese women with PCOS who had been previously poor responders regarding weight reduction with lifestyle modification and resistant to first line reproductive treatments.
Controlled ovarian stimulation (COS) enhances the efficacy of ART (Assisted reproductive technology) by permitting multiple-oocyte yields, but also alters endometrial receptivity (ER) by an advancement of endometrial development which contributes to diminished pregnancy chances. Previous reports suggest that pregnancy rates are increased following deferred frozen embryo transfers. In addition as compared to fresh embryo transfers, frozen embryo transfers seem to be associated with less affected perinatal outcomes, in particular lower risk of preterm birth, small for gestational age and caesarean section. Unfortunately, most of the current evidence is based only on preliminary reports, needing further scientific evidence. Thus, whether differing embryo transfers could restore optimal ER leading to higher live birth rate (LBR) and better obstetrical outcomes as compared to fresh embryo transfers, is actually still under investigation.
Fibroid is a frequent pathology of infertile women. Its deleterious effect on the infertility would be due to the mechanical way. The interest of the resection of intramural fibroids is discussed. It is necessary to measure the indication of a myomectomy, whatever the surgical procedure. On the one hand, it may cause important potential complications, and on the other hand, the surgery does not improve the parameters of the fertility. Thus, it is a major stake to avoid the surgical operation. A decrease of the size of these fibroids by medical treatment is then a good option. When the surgical treatment is necessary, a medical pre-surgical treatment is often proposed in order to decrease the symptomatology and to reduce the size of the fibroid to facilitate the surgery. Acetate Ulipristal (UPA) has been marketed in this indication. Following the Pearl I-II studies, the first indication in France was a pre-surgical treatment for 3 months at a dose of 5 mg per day. The Pearl III and IV studies evaluated the Esmya® administration as a long-term intermittent repeated treatment, giving to it a prominent position for the long-term management of symptomatic fibroids. Furthermore, cases of pregnancy before surgery are frequently described in women with fibroids treated by UPA for a pre-IVF surgery. 5 to 10 % of women who are managed for infertility have fibroids and only 2% to 3% have this unique cause of infertility. Then, some of patients followed in ART centers have been treated by UPA to reduce the fibroids size and/or to decrease the associate symptoms. The aim of this study is to evaluate in the different French ART centers, the impact on fertilization of UPA administration for infertile women with fibroids and to describe the modalities of its prescriptions and to collect information regarding safety tolerance profile of Esmya® in this patient population.
In a prospective observational study at a university teaching hospital, blood flow indices and serum hormone levels were compared between spontaneous and stimulated cycles in the same group of 50 patients with unexplained delayed conception.
At present, the evaluation criterion of endometrial receptivity is controversial. The development of a molecular diagnostic tool, the endometrial receptivity array (ERA) for diagnosis of endometrial receptivity . But use of this test in patients with RIF has shown that the window of implantation (WOI) is displaced in only a quarter of these patients and use of a personalized embryo transfer (pET) on the day designated by ERA improves reproductive performance with higher cost .what is known to the others'population? The morphological changes observed on histology for each specific day after ovulation were described by Noyes and his colleagues in 1950 . An endometrial biopsy that shows a difference of more than 2 days between the histologic dating and actual day after ovulation is considered to be ''out of phase''. But such pET studies according to the Noyes criterion are lacking . The aim of this study is to explore the Personal frozen-thawed embryo transfer in unexplained RIF patients according to the blinded histological dating of endometrial biopsies .
The role of micronutrients in fertility has recently gained increased attention. In women who suffer from polycystic ovary syndrome (PCOS) and infertility, we aim to test the impact of a standardized, multinutrient supplementation on the course of PCOS-specific parameters namely anti-Mullerian hormone (AMH), testosterone, and androstenedione. A total of 60 infertile women with PCOS, previously untreated, will be randomized to receive either a combined standardized multinutrient supplementation (containing folic acid, selenium, vitamin E, catechins, glycyrrhizin, coenzyme Q10 and omega-3-fatty acids; study group) or folic acid alone (control group) in a double-blinded, randomized manner. These study medications will be provided for 3 months and pre- to posttreatment levels of AMH, testosterone, and AMH will be analysed. The study will be performed at the Clinical Division of Gynecologic Endocrinology and Reproductive Medicine of the Medical University of Vienna.
Since preimplantation genetic testing (PGT) is being more frequently requested from patients as women pursue infertility treatments at an advanced age with a poorer prognosis, sometimes physicians are compelled to perform several stimulation cycles to obtain more eggs and, consequently, a greater number of biopsied embryos. Hence, the idea of carrying out this study arises as an attempt to optimize each menstrual cycle to the maximum. It is believed that the double stimulation (DuoStim) protocol could be an alternative for this group of patients, allowing to obtain a larger number of oocytes in a shorter period, thus, increasing the number of biopsied embryos and possibly decreasing the interval to achieve a successful pregnancy. The investigators aim to evaluate the potential usefulness of the DuoStim protocol for patients desiring to obtain oocytes as soon as possible. Using PGT, the investigators will compare the rate of euploid embryos per cycle in patients undergoing DuoStim protocol versus patients undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Patients will include women with advanced age and poor response. This is a unicentric, prospective, randomized, non-blind, parallel-group controlled phase IV clinical study. The investigators hypothesize that the rate of euploid embryos per cycle is similar in the DuoStim group compared to the group undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Furthermore the investigators will evaluate if there are differences regarding the number of total oocytes obtained, the number of mature oocytes, the number of biopsied blastocysts and the MitoScore index of the available euploid embryos.
