Luteal phase ovarian stimulation following oocyte retrieval: is it helpful for poor responders?
BACKGROUND Poor ovarian response and retrieval of no oocytes following ovarian stimulation for in vitro fertilization (IVF) is a challenging problem for both the patient and the clinician. FINDINGS Recent evidence indicates that folliculogenesis occurs in a wave-like fashion indicating that there are multiple follicular recruitment waves in the same menstrual cycle. This relatively new scient...
متن کاملDelayed Start Versus Conventional GnRH Antagonist Protocol in Poor Responders Pretreated With Estradiol in Luteal Phase: A Randomized Controlled Trial.
OBJECTIVE To compare the new delayed start protocol against the conventional gonadotropin (Gn)-releasing hormone antagonist protocol in poor responders (PORs). STUDY DESIGN A total of 160 women with poor response to previous in vitro fertilization (IVF) cycle were randomized either to start Gn then Cetrotide 0.25 subcutaneously (sc) added when leading follicle (DF) reach >12 mm or Cetrotide 0...
متن کاملthe impact of ovarian stimulation and luteal phase support on
background: the luteal phase defect is a common event following the ovarian stimulation. the aim of the present study was to evaluate the use of human chorionic gonadotropine (hcg) and progesterone hormones to improve the luteal phase defect. materials and methods: 60 mice were superovulated routinely with human menopausal gonadotropin (hmg) (7.5u) and hcg (10u). the mice were mated and divided...
متن کاملIndividualized controlled ovarian stimulation in expected poor-responders: an update
Controlled ovarian stimulation with subsequent multi-follicular development continues to be a keystone in ART. Evidence supports an individualized approach to ovarian stimulation, usually involving combinations of ovarian reserve tests, body mass index and age to tailor the exogenous gonadotropin dose, and potentially adjuvant treatment aiming for high safety and a shortening of time to live bi...

Background To compare a flexible, multi-dose GnRH antagonist protocol with a long GnRH .agonist protocol in poor respo MaterialsAndMethods A randomized clinical trial of 70 poor responder patients (35 patients in GnRH antagonist protocol and 35 patients in long GnRH agonist protocol) was performed at Royan Institute, Tehran, Iran. Both groups were given a fixed dose of human menopausal gonadotr...
