Mid-luteal endometrial intracrinology following controlled ovarian hyperstimulation involving use of a gonadotrophin releasing hormone antagonist.
BACKGROUND There are concerns of reduced pregnancy rates with the use of gonadotrophin-releasing hormone antagonists (GnRH antagonists) in IVF/ICSI cycles. Sex steroids and their metabolizing enzymes in the endometrium may play a vital role in embryo implantation. This study has evaluated the levels and localization of sex-steroid receptors and metabolizing enzymes, 3beta-hydroxysteroid dehydro...
متن کاملComparing gonadotrophin-releasing hormone agonists or gonadotrophin-releasing hormone antagonists in poor responder in IVF
Objective: The use of GnRH antagonist versus GnRH agonist in poor responder for patient undergoing ovarian hyperstimulation and in vitro-fertilization was compared. Materials and Methods: In this study, 23 patients underwent ovarian hyperstimulation with recombinant FSH followed by the use of GnRH antagonist (Cetrorelix) 0.25mg during the late Follicular Phase. These patients were compared to 2...
متن کاملHigh dose gonadotrophin-releasing hormone antagonist (ganirelix) may prevent ovarian hyperstimulation syndrome caused by ovarian stimulation for in-vitro fertilization.
This case report describes the first attempt to treat imminent ovarian hyperstimulation syndrome (OHSS) by using a gonadotrophin-releasing hormone (GnRH) antagonist. A 33 year old, normo-ovulatory woman undergoing in-vitro fertilization received daily subcutaneous injections of 150 IU of recombinant follicle-stimulating hormone (recFSH) from cycle day 2, together with GnRH antagonist (ganirelix...
متن کاملControlled ovarian hyperstimulation and IVF pregnancy prognosis.
IVF (in vitro fertilization) often represents the ultimate step in our attempt to treat infertility. Nowadays this method is more and more used, couple's expectations are higher and higher, so that optimizing the chance that one IVF pregnancy became a healthy newborn child is becoming an important issue. In this study we analyzed the controlled ovarian hyperstimulation impact on IVF pregnancy p...
متن کاملLong-Acting Luteinizing Hormone-Releasing Hormone Agonist for Ovarian Hyperstimulation Induced by Tamoxifen for Breast Cancer
Tamoxifen treatment for breast cancer may induce ovarian cysts and supraphysiological levels of serum estrogen. We report successful management with luteinizing hormone-releasing hormone (LHRH) agonist of ovarian hyperstimulation induced by tamoxifen. A 49-year-old woman was operated on for invasive ductal carcinoma of the right breast. She received breast irradiation and adjuvant tamoxifen the...
