Pre-treatment human chorionic gonadotrophin (hCG) ratio in the management of non-tubal ectopic pregnancy

Choriocarcinoma-like human chorionic gonadotrophin (HCG) and HCG bioactivity during the first trimester of pregnancy.

The objective of this study was to evaluate the distribution of choriocarcinoma-like human chorionic gonadotrophin (HCG) isoforms during first trimester pregnancy and their relationship with in-vitro HCG bioactivity. This was done by means of a retrospective analysis of patients' sera with first trimester normal intrauterine and abnormal (ectopic) pregnancies. Serum samples were obtained from 3...

Measurement of Human Chorionic Gonadotrophin (hCG) in the management of Trophoblastic disease

Human Chorionic Gonadotrophin (hCG) is mainly a product of the syncytiotropoblastic cells of the placenta although it is also secreted, in lesser quantities, by cytotrophoblastic cells and several nonplacental tissues. It is produced in gestational trophoblastic neoplasms (GTN) and maybe seen in nontrophoblastic neoplasms (Stenman, 2006). hCG is essential in pregnancy as it promotes transformat...

Laparoscopic Management of Tubal Ectopic Pregnancy

OBJECTIVES To study the surgical morbidity associated with laparoscopic management of tubal ectopic pregnancy compared with that of open laparotomy. METHODS A retrospective study in an academic tertiary obstetrics and gynecology referral center was conducted from 2005 through 2007. Forty-nine patients who had pathology-confirmed tubal ectopic pregnancies were divided into 2 groups, laparoscop...

Molar Pregnancy Presents as Tubal Ectopic Pregnancy

Expression of luteinizing hormone/human chorionic gonadotrophin (LH/HCG) receptor mRNA in the human ovary.

The gonadotrophins follicle stimulating hormone (FSH) and luteinizing hormone (LH) are key hormones in the regulation of ovarian function. In the present study, the expression of LH/human chorionic gonadotrophin (HCG) receptor mRNAs in the human ovary was examined. Northern blot analysis was used to measure relative amounts of LH/HCG receptor mRNA, and in-situ hybridization was used to localize...
