Progesterone Diurnal Rhythm During Ovarian Stimulation for IVF

2016-11-30 15:45:47 | BioPortfolio

Summary

To evaluate the influence of circadian rhythm on progesterone levels during follicular phase of natural cycle and during follicular phase of controlled ovarian stimulation during IVF.

Description

The primary aim of this study is to determine the circadian rhythm of progesterone in a stimulated cycle. Sample size calculations show that the study needs to recruit 10 women to show any significant differences in progesterone secreted in the morning at 8 am compared to that secreted in the evening at 8 pm. We have increased the number of participants to 12 in order to compensate for any possible drop outs. The hormones FSH, LH, Progesterone and Estradiol will be measured at days 2/3, 8, 10 and 12 of a normal and stimulated cycle so that each patient serves as her own control.

We hope that this study will provide the basis to establish the optimal blood sampling time for progesterone measurement and to more accurately determine the cut-off level for progesterone for favourable pregnancy outcomes in ART.

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.

Methods used for assessment of ovarian function.

A group of inherited enzyme deficiencies which feature elevations of GALACTOSE in the blood. This condition may be associated with deficiencies of GALACTOKINASE; UDPGLUCOSE-HEXOSE-1-PHOSPHATE URIDYLYLTRANSFERASE; or UDPGLUCOSE 4-EPIMERASE. The classic form is caused by UDPglucose-Hexose-1-Phosphate Uridylyltransferase deficiency, and presents in infancy with FAILURE TO THRIVE; VOMITING; and INTRACRANIAL HYPERTENSION. Affected individuals also may develop MENTAL RETARDATION; JAUNDICE; hepatosplenomegaly; ovarian failure (OVARIAN FAILURE, PREMATURE); and cataracts. (From Menkes, Textbook of Child Neurology, 5th ed, pp61-3)
