Gonadotropin-releasing Hormone (GnRH) Antagonist During 3 Days

2014-08-27 03:14:58 | BioPortfolio

Summary

In this prospective study, the investigators would like to show whether ovarian stimulation with pretreatment of a GnRH antagonist during 3 consecutive days at initiation of the cycle, is possible.

Description

A recently accepted study demonstrated that raised progesterone levels can be normalized through administration of a GnRH antagonist during three subsequent days prior to the start of gonadotropin stimulation in a GnRH antagonist protocol. This regimen, after normalisation of the progesterone value, allows controlled ovarian hyperstimulation (COH). Since this regimen is valid in case of elevated progesterone, GnRH antagonists pretreatment may prove to be a valid tool for scheduling IVF treatment in patients with normal progesterone values on day 2 of the cycle. In this prospective randomised trial, we study the impact of administration of a GnRH antagonist during 3 consecutive days at initiation of the cycle.

Medical and Biotech [MESH] Definitions

A complication of OVULATION INDUCTION in infertility treatment. It is graded by the severity of symptoms which include OVARY enlargement, multiple OVARIAN FOLLICLES; OVARIAN CYSTS; ASCITES; and generalized EDEMA. The full-blown syndrome may lead to RENAL FAILURE, respiratory distress, and even DEATH. Increased capillary permeability is caused by the vasoactive substances, such as VASCULAR ENDOTHELIAL GROWTH FACTORS, secreted by the overly-stimulated OVARIES.

Cessation of ovarian function after MENARCHE but before the age of 40, without or with OVARIAN FOLLICLE depletion. It is characterized by the presence of OLIGOMENORRHEA or AMENORRHEA, elevated GONADOTROPINS, and low ESTRADIOL levels. It is a state of female HYPERGONADOTROPIC HYPOGONADISM. Etiologies include genetic defects, autoimmune processes, chemotherapy, radiation, and infections.
