Filter by:The aim of this randomized controlled trial is to compare the efficacy of oral dydrogesterone vs. micronized vaginal progesterone for luteal phase support in frozen-thawed embryo transfer cycles.
The purpose of this study is to understand why some women are infertile (unable to conceive a child). The investigators hope to learn if an endometrial biopsy after egg retrieval is feasible for detecting biomarkers for endometriosis and predicting implantation and pregnancy rate after embryo transfer. This study design will provide for the first time, an opportunity to compare endometrial biopsy material from hyperstimulated (gonadotropin treated) subjects after egg retrieval. If successful, it would provide a new protocol for women with unexplained infertility or those with known endometriosis to avoid poor IVF outcomes.
Infertile women undergoing hysteroscopy for diagnostic or therapeutic indication are asked to donate a sample of endometrium. Endometrial samples of study participants are examined for signs of chronic endometritis by immunohistochemical analysis. High-throughput sequencing of the microbial 16s ribosomal ribonucleic acid (rRNA) subunit is performed to identify and quantify the microbes present in the sample. Obstetric and reproductive outcome is recorded 12 months after hysteroscopy (telephone interview).
Uterine septum is the most common congenital uterine malformation. It accounts for approximately 35% of all uterine malformations, while the frequency of uterine malformations in the general fertile population is estimated to be between 1% and 4%. The presence of a uterine septum is associated with subfertility and a high incidence of obstetric complications, such as spontaneous abortion, 3-fold increase in preterm premature rupture of the membranes (PROM), 6-fold increase in preterm delivery, malpresentation at delivery, caesarean section, and increased perinatal morbidity and mortality. Some studies have found that surgical resection of the uterine septum improves pregnancy outcomes and significantly reduces the risk of preterm delivery. Therefore, the risk for a short-term adverse outcome and long-term sequelae due to preterm delivery such as intraventricular hemorrhage, necrotizing enterocolitis, sepsis, patent ductus arteriosus, retinopathy, deafness, chronic lung disease, cerebral palsy, perinatal death, and impaired mental development in women with uterine septum could be lowered by performing a relatively simple and safe hysteroscopic septum resection (HSR). However, there are two major concerns regarding HSR: cervical incompetence due to excessive dilatation during hysteroscopy and the rare yet serious complication of uterine rupture in subsequent pregnancy or delivery. Considering these elements, the aim of this study will be to evaluate the rate of preterm delivery in singleton pregnancy comparing primary infertile women who underwent HSR and who did not undergo the same procedure, with our without in vitro fertilization.
Randomized trial comparing the efficacy of two different times of administration of cabergoline in patients undergoing controlled ovarian stimulation and oocyte collection.
Hysteroscopy is an important tool in the evaluation of sterility. Assessing tubal patency during hysteroscopy seems highly relevant, particularly when it allows for a low cost, fast, gentle, and accurate way of gathering information that may guide clinical care. Therefore, it is important to know which technique is the best. Thus, the primary aim of this study is to evaluate the reliability of (1.) the hysteroscopic visualization of a "tubal flow" and (2.) the "Parryscope technique" as compared to the gold standard, namely laparoscopic chromopertubation. In a prospective, randomized study, the following women are enrolled: (1.) The patient is subfertile, defined as being unable to become pregnant within a year despite unprotected sexual intercourse. It is also within the standard of care to be presumed subfertile if one has tried for six months and has known risk factors that would hinder conception, including but not limited to anovulation and endometriosis. (2.) A concurrent diagnostic hysteroscopy and laparoscopy with chromopertubation are performed at the Clinical Division of Gynecological Endocrinology and Reproductive Medicine at the Medical University of Vienna. Hysteroscopic evaluation of tubal patency (either by a positive "tubal flow" or a visible flow of air bubbles in the "Parryscope technique") and the result of the laparoscopic chromopertubation (tubal patency existing or not existing) will be the primary outcome parameters. A total 60 patients are enrolled (30 patients in the "flow assessment" group, 30 patients in the "Parryscope" group) and randomization is performed as block randomization in 4 blocks.
The study will describe the effectiveness of ovarian stimulation in correlation with female infertility causes in a Lebanese population: a comparative study using 5 protocols of ovulation induction (treatment with "A" gonadotropins alone, "B" short GnRH agonist, "C" multiple-dose GnRH antagonist, "D" long GnRH agonist and "E" combined protocol of GnRH antagonist and agonist) and the outcomes of ICSI. This comparative study will help clinicians to select the relevant protocol of ovarian stimulation related to the female infertility disorders.
This study is a RCT to examine whether DHEA is capable of improving results for poor responders to ovarian stimulation during IVF treatment
The objective of the study is to gain a better understanding of the gene expression changes in the endometrial biopsy especially whether the endometrium has reached a receptive status, i.e. the implantation window, or not.
This study aims to evaluate apical pelvic compartment support in infertility patients at the time of hysteroscopy. Apical pelvic compartment evaluation for pelvic organ prolapse will be performed in infertility patients undergoing hysteroscopy.
