Human chorionic gonadotropin (HCG) is an important tumor marker in the diagnosis and monitoring of treatment response childhood cancers such as germ cell tumors liver tumors. The effect chronic kidney disease (CKD) on increased HCG not a well-researched issue. elevation unknown cause only causes diagnostic confusion, but also economic loss by necessitating many unnecessary examinations.In curre...

Background To assess the usefulness of premature luteinization hormone (LH) surge prevention in an intrauterine insemination (IUI) cycle by GnRH antagonist administration MaterialsAndMethods 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 anta...

Follicular fluid obtained from medium or large bovine ovarian follicles inhibited ovarian luteinizing hormone/human chorionic gonadotropin sensitive adenylate cyclase in a dose-dependent manner (150'3 mg follicular fluid protein/ml). The inhibitory activity was excluded by Sephadex G-10 and was fully retained following treatment with charcoal. Fluoride-stimulated enzyme activity was not inhibit...

The role of RNA synthesis was investigated in the action of chorionic gonadotropin on ovaries of immature rats. Chorionic gonadotropin accelerates the ovarian incorporation of [3H]uridine in uivo into rapidly labeled nuclear RNA within 10 min after hormone injection. Analysis of the RNA base composition, expressed as base ratio (A + U):(G + C), shows that hormonal stimulation of the rate of [3H...

The aim of this study was to investigate 2 quantification criteria to evaluate the developmental condition of follicles cohort and clarify their impacts upon the determining of human chorionic gonadotropin trigger timing and the reproductive outcome: the proportion of mature follicles in growing follicles cohort on the day of human chorionic gonadotropin trigger and the peak estradiol level per...
