In circumstances such as in vitro fertilization (IVF) or in patients with luteal phase defect, one needs to ensure the establishment of pregnancy as soon as possible. At the same time, a question arises: How can a physician make sure that the β-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M inject...

OBJECTIVES To reevaluate both discriminatory and threshold levels associated with visualization of gestational sacs, yolk sacs, and fetal poles in patients presenting with vaginal bleeding, pain, or vaginal bleeding and pain in the first trimester of pregnancy using current ultrasonographic technology. METHODS We reviewed the records of patients with first-trimester vaginal bleeding, pelvic p...

The diagnosis of acephalocystis racemosa and missed abortion based on transvaginal ultrasonography and serum β-HCG monitoring was studied in this paper. The main contents of variance analysis were mainly introduced and at the same time, the main contents and research methods of hydatidiform mole detection and missed abortion diagnosis were also expounded. The results show that there are some di...

Human luteinizing hormone (hLH) and human chorionic gonadotropin (hCG) are human glycoprotein hormones each consisting of two subunits, an identical α-subunit and a unique β-subunit, that form noncovalent heterodimers. Structurally, β-hCG shares a high degree of sequence similarity with β-hLH, including a common N-glycosylation site at the N-terminus but differs mainly in the presence of an ext...

BACKGROUND Initial low maternal serum β-human chorionic gonadotropin (β-hCG) is a good predictor of early pregnancy demise. Our objective was to determine its predictive value in determining the long-term outcome in ICSI pregnancies. METHODS A retrospective cohort study was designed at the Saudi Center for Assisted Reproduction. Two hundred and sixty-one women with ICSI pregnancies were follo...

background and objective: hyperemesis gravidarum (hg) is defined as vomiting sufficiently severe to produce weight loss, dehydration, electrolyte abnormalities. interleukin-6 (il-6), a pro-inflammatory and trophoblast-derived cytokine has ability to induce trophoblasts to secrete human chorionic gonadotropin (hcg). the purpose of our study was to assay the level of il-6 and β-hcg in serum of pr...

OBJECTIVE The combination of mifepristone and misoprostol is an established method for induction of early first trimester abortion, but there is no consensus about the best evaluation of treatment outcome. We evaluate serum Angiopoietin-2 (Ang-2) and β human chorionic gonadotropin (β-hCG) in women who had undergone a medical abortion as markers of prolonged uterine bleeding (PUB). METHODS Pro...
