Filter by:In an era of delayed fertility plans, there is an increasing need for a reliable method to predict ovarian reserve and responsiveness. The current tests include serum FSH, Inhibin B, Mullerian inhibiting factor (MIF) and ultrasonographic measures such as ovarian volume and number of antral follicles are non-specific and with questionable reliability. The biochemical tests represent the function of production of androgens, as a predictor of ovarian reserve, has not been tested yet. Working hypothesis and aims: testing the prognostic capability of hCG stimulating test of theca cells for estimating the ovarian reserve, and by that to calculate better the chance for IVF cycle success
To investigate the effect of daily administration of low-dose aspirin, compared to placebo, on IVF and ICSI outcome.
BACKGROUND: A new effective way, transvaginal ultrasound-guided ovarian interstitial laser-coagulation treatment, in management of anovulation in patients with polycystic ovary syndrome (PCOS), has been presented in the data published. But, the optimal number of laser coagulation points in the ovarian interstitial to be applied at the procedure is unclear. This clinic trial aims to explore an optimal laser dose for this new protocol. METHODS: Fifty-six PCOS women with clomifene citrate-resistant underwent ultrasound-guided transvaginal ovarian interstitial YAG-laser treatment. By random list tableļ¼all subjects were randomly divided into four groups in terms of the number of laser coagulation points made in their ovaries as follows: group A, one coagulation point per ovary; group B, two points; group C, three points; group D, four to five points. The size of each point was about 10 mm in diameter on the ovarian plane monitored by transvaginal ultrasound. Postoperative ovulation rate, pregnancy rate and some biochemical parameters were compared among four groups.
Patients who have undergone in vitro fertilization (IVF) and produced four or less follicles or had four or less oocytes (eggs) retrieved are often referred to as poor responders. We will refer to these patients from this point forward as "low responders" to avoid using a potentially offensive label. We are currently using 2 different IVF medication protocols in our practice to treat low responder patients with infertility: the "Microdose Leuprolide" protocol and the "Luteal Phase Ganirelix" protocol. We would like to conduct a randomized-controlled trial and randomize patients to one treatment group or the other to determine which medication protocol is more effective in treating infertility in this group of patients.
Oocyte donation is a well established procedure in assisted reproduction treatments (ART). It is demonstrated that the use of hormonal substitution therapy, for the synchronization of the cycles between the recipients and the donors, provides good results, similar to the ones obtained with the natural cycle. In the patients - recipients with preserved ovarian function, the recipient's natural cycle is annulled, thus preventing the spontaneous Luteinizing Hormone surge. Simultaneously and while waiting for the suitable donor, her endometrium is prepared. When the donation occurs and fertilization with the husband sperm takes place, her cycle is stimulated again in order to synchronize her window of implantation with the donor's ovulation. Two different medications are commonly used to inhibit spontaneous ovulation: either GnRHa agonist or GnRH antagonists. The present study consists of the comparison between the single dose GnRH agonist (Decapeptyl 3,75 IM) and the 7 day dosage of GnRH antagonist (Cetrotide 0,25 mg). The administration of GnRHa is used fundamentally as a long liberation formulation, administered in a single intramuscular injection (IM), which is more practical in terms of use. Nevertheless, the unnecessary persistence and the potentially unfavorable action of GnRHa during the luteal phase and early gestation have questioned its use. The recovery of the Hypophysarian function begins only 8 weeks after the single injection of long liberation of triptorelina 3.75 mg. The GnRH antagonist (Cetrotide 0,25 mg) makes the hypofisary inhibition shorter than with the analogues and can prepare similar endometrium characteristics as a natural cycle. The recipients will be assigned randomly to a group of treatment or another.
To prove efficacy of an immunomodulator called pentoxifylline in the treatment of endometriosis in infertile patients undergoing laparoscopy surgery
This prospective randomized trial evaluates whether one can predict which infertile women with endometriosis who are candidates for in vitro fertilization will benefit from prolonged therapy with a GnRH agonist by the determination of the absence of endometrial expression of the integrin, alpha v, beta 3 vitronectin. This is a prospective randomized trial in which all patients will undergo endometrial biopsy prior to initiation of ovarian stimulation for in vitro fertilization and then undergo randomization to a three month course of a depot preparation of the GnRH agonist leuprolide acetate in depot suspension prior to ovarian stimulation or standard therapy. prio
We are examining whether pregnancy rates differ based on day of embryo transfer in patients who replace all available embryos after an In vitro Fertilization (IVF) cycle. Patients must be undergoing IVF treatment at Stanford University and patients will not receive compensation for their participation (no medical costs covered or patient payment for participation).
This is a multi-center study to evaluate the effects of DR-2011 compared to a progesterone gel in women undergoing in vitro fertilization with fresh eggs. The overall study duration will be approximately 12 months and will involve ovarian suppression/stimulation protocols as well as egg retrieval.
OBJECTIVE: To compare the effectiveness of letrozole and clomiphene citrate (CC) in patients with anovulatory infertility. DESIGN: Open, prospective, randomized, parallel group, multicentric, comparative trial. SETTING: Out patient clinics of infertility centers in India. PATIENT(S): Fifty-five patients with anovulatory infertility were recruited. Twenty-seven patients (59 cycles) were given letrozole and twenty-eight patients (68 cycles) were given CC. Both drugs were given orally on days 3-7 of menstrual cycle. INTERVENTION(S): Letrozole, CC, ovulation induction, vaginal micronized progesterone, IUI.
