Filter by:Our and others experience suggest that in some cases delaying oocyte pick up (OPU) for more than 39 hours after hCG injection may be of benefit. We plan to apply this to 20 women in whom less than 20% of oocytes were found suitable for intracytoplasmic sperm injection. The delay will be for up to an interval of 47 hours from hCG to OPU.
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.
The purpose of this study is to compare two luteal support protocols in In vitro fertilization patients (IVF) and are at risk of developing ovarian hyperstimulation syndrome (OHSS). We would like to determine whether luteal Decapeptyl on days 3, 6,9 post ovulation triggering is as good as low dose hCG on day 3 post triggering..
Infertile couples who come for evaluation and treatment in IVF unit could be under psychological stress. Many authors in the past suggested that stress itself is one of the factors that directly influence fecundability rate. In couples treated in IVF unit, the investigators aim to measure chronic stress by measuring hair cortisol level (as a marker for chronic cortisol release) and by filling different questionnaires.
This study is a multicenter, randomized-control-trial. This study select 1184 Infertile patients associated with endometriosis diagnosed by laparoscopy surgery. Patients are going to be divided into two groups according to 1:1 ratio randomly assigned to receive GnRH-a. Cumulative pregnancy rate, end of treatment to natural pregnancy time, accept the assisted reproductive treatment rate, miscarriage rate, live birth rate will be recorded.
The aim of this study is to measure the expression of HOXA10 and HOXA11 in the endometrium of infertility patients with an endometrial polyp before and after polypectomy. HOXA10 and HOXA11 are well-established markers of implantation. It is uncertain as to whether an endometrial polyp interferes with embryo implantation. A higher expression of HOXA10 and HOXA11 after polypectomy can indicate that endometrial polyp does interfere with embryo implantation.
Premature ovarian insufficiency (POI) is a life-changing condition that affects women in their reproductive age. There is a lack of reports which focus on how to improve the reproductive outcome of these women who wish to conceive spontaneously or use assisted conception with their own oocytes. However, one could surmise that it is important to lower gonadotropin levels into the physiological range before embarking on any treatment, even if natural conception is the only choice for the woman/couple.
The aim of this study is to determine whether different needle gauges influences the quality of the aspirated oocytes during in-vivo fertilization (IVF).
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.
Two common SNPs are located in linkage disequilibrium in exon 10 of FSHR. The 2039 A>G variant is regularly analyzed to characterize the exon 10 haplotype. In the last years, it has been showed an influence of FSHR 2039 A>G on FSH levels, testicular volume, sperm concentration and the total sperm count. A recent Cochrane review showed a beneficial effect on live birth and pregnancy of gonadotrophin treatment for men with idiopathic male factor subfertility. Which FSHR polymorphism can benefit from FSH treatment is clinically very important, in particular for what regards nonidiopathic patients. In many andrological units, patients underwent adiuvant therapy with purified or recombinant FSH after varicocelectomy. FSH treatment in patients after varicocelectomy could improve spermatogenesis, but there aren't multicentric trials that confirm its validity. Usually, in our hospital only patients with a morphologic aspect of hypospermatogenesis underwent therapy with purified or recombinant FSH, because this therapy is not much useful in patient with Partial Sertoli-cell-only syndrome or maturation arrest. The purpose of our study is to correlate "non responder" patients who underwent FSH adiuvant therapy after varicocele surgery with a p.N680S FSHR polymorphism. Moreover the investigators suppose that "non responder" patients can beneficiate from a high-dose therapy with FSH. This is a prospective intervention study in which are recruited males with OligoAstenoTeratozoospermic (OAT) and varicocele. The partecipants will undergo subinguinal microsurgical varicocelectomy (Marmar technique) and needle aspiration testicular cytology (Foresta technique).
