OBJECTIVE To study the incidence of monozygotic twins (MZT) in blastocyst and cleavage stage ET. DESIGN Retrospective review. PATIENT(S) Four hundred ninety-six women undergoing IVF/intracytoplasmic sperm injection cycles at a private assisted reproductive technology (ART) center. INTERVENTION(S) Patients undergoing ART were divided according to the stage of ET into blastocyst transfer (B...

background: recent reports have suggested that ultrasound-guided embryo transfer (ug-et) might improve pregnancy rates. objective: to determine whether transabdominal ug-et is a useful tool for increasing pregnancy and implantation rates in patients undergoing ivf or icsi. materials and methods: a prospective randomized clinical trial was conducted in 180 patients in order to compare embryo tra...

the microdose gnrh agonist (gnrh-a) flare protocol may have a particular value for previously poor responders in whom it has been observed to stimulate dramatic increases in serum fsh. the purpose of this study was to determine the effects of microdose gnrh-a in poor responders. this is a clinical trial with before and after design. this study was done in research and clinical center for infert...

BACKGROUND Gonadotrophin-releasing hormone (GnRH) agonist is used for controlling ovarian stimulation in assisted reproductive technology (ART) cycles which has some benefits. OBJECTIVE To compare the efficacy of two different formulations of GnRH agonist: short-acting and long-acting, for ART protocols.

The aim of this study is to evaluate the effectiveness Dydrogesterone in PPOS protocols for IVF/ICSI cycles or Oocyte cryopreservation both blocking LH surge as well number metaphase II oocytes. 550 plus 186 oocyte from January 2018 December 2020, no age restriction. All patients were given Follitropin delta (Rekovelle®, Ferring Pharmaceuticals) Menotropin (Menopur®, a fixed daily SC dose. Clin...

background: one of the major and life-threatening side effects of assisted reproductive technique (art) is ovarian hyperstimulation syndrome (ohss). the available data however, have been showed that both cabergoline (anti vegf) and coasting reduce the severity of ohss. objective: we aimed to compare coasting and cabergoline administration in prevention of severe ohss. materials and methods: a t...

This paper introduces high-security constant-time variable-base-point Diffie–Hellman software using just 274593 Cortex-A8 cycles, 91460 Sandy Bridge cycles, 90896 Ivy Bridge cycles, or 72220 Haswell cycles. The only higher speed appearing in the literature for any of these platforms is a claim of 60000 Haswell cycles for unpublished software performing arithmetic on a binary elliptic curve. The...
