Benign Prostatic Hyperplasia in a 13-Year-Old Boy

The Annals of African Surgery, 2023
Benign prostatic hyperplasia (BPH) is most common in men 40 years and above. It rarely occurs in childhood. As a result of the scarcity of cases, the pathogenesis is not clear, and treatment of BPH in this age group is challenging. This report focuses on

Variants of human chorionic gonadotropin from pregnant women and tumor patients recognized by monoclonal antibodies [PDF]

, 1993
In biological fluids, hCG and its free alpha- (hCG alpha) and beta-subunits (hCG beta), occur in multiple forms. These various forms differ at the molecular level primarily in glycosylation, but also differ in protein backbone modifications corresponding

Human chorionic gonadotropin and risk of pre‐eclampsia: prospective population‐based cohort study

Ultrasound in Obstetrics and Gynecology, 2019
Abnormal placentation in early pregnancy may play a role in the pathogenesis of pre‐eclampsia. Human chorionic gonadotropin (hCG) regulates placental development and angiogenesis and may affect the ratio of soluble fms‐like tyrosine kinase‐1 (sFlt‐1) and

Beta-Human Chorionic Gonadotropin Producing Osteosarcoma of the Sacrum in a 26-Year-Old Woman: A Case Report and Review of the Literature

Case Reports in Pathology, 2015
Ectopic secretion of beta-human chorionic gonadotropin is considered a poor prognostic marker in epithelial tumors. However, very few cases have been reported in sarcomas.

Efficacy of Follicle-Stimulating Hormone (FSH) Alone, FSH + Luteinizing Hormone, Human Menopausal Gonadotropin or FSH + Human Chorionic Gonadotropin on Assisted Reproductive Technology Outcomes in the “Personalized” Medicine Era: A Meta-analysis

Frontiers in Endocrinology, 2017
Setting Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) act on the same receptor, activating different signal transduction pathways. The role of LH or hCG addition to follicle-stimulating hormone (FSH) as well as menopausal gonadotropins (

Prognostic factors in seminomas with special respect to HCG: Results of a prospective multicenter study [PDF]

, 1999
Objective: In a prospective multicenter trial, it was our intention to elucidate clinical prognostic factors of seminomas with special reference to the importance of human chorionic gonadotropin (HCG) elevations in histologically pure seminomas. Methods:

Late-onset ovarian hyperstimulation syndrome developing during ovarian stimulation in an ectopic pregnancy: a case report

Journal of Medical Case Reports, 2020
Background Ovarian hyperstimulation syndrome is normally induced by ovarian stimulation drugs. Severe cases of ovarian hyperstimulation syndrome involve complications such as renal failure and thrombosis. Evidence has recently been developed for a method
