Human chorionic gonadotropin (hCG) is no longer a single, omnipotent ovulation triggering option. Gonadotropin releasing hormone (GnRH) agonist, initially presented as a substitute for hCG, has led to a new era of administering GnRH agonist followed by hCG triggering. According to this new concept, GnRH agonist enables successful ovum maturation, while hCG supports the luteal phase and pregnanc...

background: to assess the usefulness of premature luteinization hormone (lh) surge prevention in an intrauterine insemination (iui) cycle by gnrh antagonist administration materials and methods: sixty patients with unexplained or mild male infertility or minimal to mild endometriosis were enrolled in this prospective randomized controlled trial. there were twenty patients in group a (with gnrh ...

( Obstet Gynecol . 2021;137:355–370) Gestational trophoblastic disease (GTD) refers to rare processes originating from the placenta that require timely and appropriate management. GTD includes partial or complete hydatidiform moles (HM), as well severe gestational neoplasia (GTN) related tumors. Obstetrician-gynecologists are more likely be involved in care of women with HM who have unclear dia...

We analyse data from a study involving 173 pregnant women. The data are observed values of the β human chorionic gonadotropin hormone measured during the first 80 days of gestational age, including from one up to six longitudinal responses for each woman. The main objective in this study is to predict normal versus abnormal pregnancy outcomes from data that are available at the early stages of ...

In this report we show that the mRNA level for the estrogen receptor (ER) is regulated by 8-bromo cyclic AMP (8-Br-cAMP) and human chorionic gonadotropin in a mouse tumor Leydig cell line (MA-10 cells). When the MA-10 cells were cultured in the presence of the cAMP analogue for varying time periods, a transient increase in the level of ER mRNA was observed. Short time incubation (0-2 h) with 8-...

Early pregnancy bleeding is a common presentation in the emergency setting. Traditionally, its assessment relied on clinical findings, including pelvic examination. However in recent years, ultrasonography and quantitative beta human chorionic gonadotropin assays have gained prominence and are now first-line in diagnosing early pregnancy bleeding. Accordingly, the role of pelvic examination in ...
