Gonadotrophin Releasing Hormone: Its Significance in Gynaecology

Gonadotrophin-releasing hormone.

Comparing gonadotrophin-releasing hormone agonists or gonadotrophin-releasing hormone antagonists in poor responder in IVF

Objective: The use of GnRH antagonist versus GnRH agonist in poor responder for patient undergoing ovarian hyperstimulation and in vitro-fertilization was compared. Materials and Methods: In this study, 23 patients underwent ovarian hyperstimulation with recombinant FSH followed by the use of GnRH antagonist (Cetrorelix) 0.25mg during the late Follicular Phase. These patients were compared to 2...

Analogues of gonadotrophin releasing hormone.

Two types of burst firing in gonadotrophin-releasing hormone neurones.

Gonadotrophin-releasing hormone (GnRH) neurones fire spontaneous bursts of action potentials, although little is understood about the underlying mechanisms. In the present study, we report evidence for two types of bursting/oscillation driven by different mechanisms. Properties of these different types are clarified using mathematical modelling and a recently developed active-phase/silent-phase...

Treatment with gonadotrophin releasing hormone analogue in advanced prostatic cancer.

Repeated administration of long acting analogues of gonadotrophin releasing hormone diminishes gonadal function and in men decreases testosterone concentrations; for this reason the effect of the analogue buserelin was studied in prostatic carcinoma. Twelve consecutive patients with newly diagnosed locally advanced or metastatic carcinoma of the prostate were treated. Each patient received intr...
