( 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 ...

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 ...

By using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (HCG), fairly good clinical therapeutic efficacy has been obtained in the treatment of infertility. However, difficulties are brought about due to the ovarian hyperstimulation syndrome (OHSS) easily induced by these two drugs. Therefore, we attempted to use acupuncture instead of HCG in the induction of ovulation from...

The temporal relationship between redistribution of receptors to lutropin (luteinizing hormone)/human chorionic gonadotropin in cultured rat ovarian granulosa cells and the cellular response to hormonal challenge were studied. Visualization of receptor-bound human chorionic gonadotropin by indirect immunofluorescence, with hormone-specific antibodies after fixation with 2% formaldehyde, reveale...
