Filter by:The basis for obesity's impact on reproduction is not well characterised and there is a controversy whether the key organ influenced by it are the ovaries or the uterus. Insulin sensitizers ameliorate insulin resistance in obese patients. This study seeks to determine if Metformin helps to increase fecundability by affecting the uterus in women undergoing ART. As a surrogate marker- flows in the uterus will be tested during the treatment.
Early ovarian reserve decreased is one of the main causes of infertility for women after 35 years. The relationship between this decreased and exposure to chemicals, including persistent endocrine disruptors or organic solvents, has been little studied. However, several in vivo or in vitro experimental studies suggested that these chemicals may impaired ovarian function. The main objective is to study the relationship between early ovarian reserve decreased and exposure to persistent organic pollutants. The secondary objectives are to study the relationship between early ovarian reserve decreased and exposure to organic solvents and heavy metals. Multicenter case-control study. This project will permit to increase the knowledge concerning the etiology of early decreased ovarian reserve. Considering that exposure of interest are frequent, the results may be important in a public health perspective. If associations are observed in this study, the results may encouraged prevention strategy.
The purpose of this study is to study the effects of letrozole and sequential clomiphene in ovulation and pregnancy in PCOS patients.
This study will examine the feasibility of initiating a uterine transplant program for Absolute Uterine Factor Infertility (AUFI) at Brigham and Women's Hospital. The investigators plan to screen 30 patients with a goal of enrolling 10 patients. (5 donors and 5 recipients) After careful screening, appropriate candidates will undergo IVF, Uterine Transplantation, Embryo Transfer, Pregnancy and Delivery. Once the uterus is explanted, five years of follow-up is planned.
Oocyte maturation requires a lot of energy, which is provided by the mitochondria via the synthesis of ATP. The majority of patients with advanced maternal age (AMA) have poor egg quality. One of the reasons depends on oxidative phosphorylation of Pyruvate to undergo maturation; on the contrary, the cells of the cumulus (CC) show great activity glycolytic so that these cells are able to provide ATP(adenosine triphosphate and energy substrates to the oocyte. The goal of this work is to analyze the mitochondrial function and energy production in oocyte donors compared with a group of women of advanced maternal age subject to a same ovarian stimulation Protocol
Prevalence of anti-H.pylori IgG in serum of women with unexplained infertility and comparing that with it's prevalence in fertile women.
The objective of our observational prospective study will be to compare, for women treated for infertility and included in a ICSI program, the implantation rate and delivery rate obtained after the transfer of a single blastocyst , chosen in a group of patients on the basis of the embryo morphology and in the other group on the basis of both embryo morphology and follicular fluid cytokines content. 100 IVF infertile patients , aged 32-39 years, with normal ovarian reserve, previously stimulated for their first cycle with standard short protocol (GnRH-Ant) and r-FSH alone, who have had a low ovarian response, Fort < 50% ( FORT Criteria, 2012; FORT= PFCX100/AFC), will be treated for the second cycle with standard short protocol (GnRH-Ant) and r-FSH plus r-LH , according to the standard established by our clinical practice. Patients will be part of one of the following groups: Group 1: single embryo transfer on day 5, according to standard embryo morphological criteria Group 2: single embryo transfer on day 5, chosen on the basis of both embryo morphological criteria and levels of cytokines measured in the individual FF.
The purpose of this study is to match the genetic component and clinical attributes of anovulatory patients with response to clomiphene treatment. By improving our understanding on patient-specific clomiphene response will allow optimization of treatment, reduction of side-effects and shorten the time-to-pregnancy.
On the basis of the current study, amlodipine seems to be a promising drug on improving uterine, ovarian blood flow, size of pre-ovulatory follicle, midluteal progesterone level and pregnancy outcome in patients with pco.
In spite of all progress realized in the field of assisted reproduction the pregnancy rate by In vitro fertilization (IVF) in France, across indications, is only 23% after IVF cycle. Different causes may account for these failures and that, during all stages of pregnancy. Recent studies have investigated an essential step in fecundation : uterine receptivity. Some teams have shown that a lot of immunological factors would have very significant in this step, by them possible expression in this process. Other studies looked at genes modulation, essential to implantation, with endometrium manipulation, simple, such as endometrial biopsy (EB). The last findings published on this subject, but after 2 IVF failures, are most encouraging because the pregnancy rate for these teams after just endometrial local injury (EB after 2 IVF failures) is well above their usual pregnancy rate. Some teams have focused on immunoassay of endometrial biopsy, in order to profile uterine receptivity and suggest with results, suitable treatment for each patient (ongoing study). EB is quick, easy, make in a simple consultation and with a low cost, contrary to immunological study, which depend of ultra-specialized laboratories and therefore with an important cost.
