This study investigated the biochemical relationship between human follicular/oocyte
maturity and the levels of follicular fluid purines. Intrafollicular levels of purine metabolites …

Adenosine (ADO) in low micromolar levels and hypoxanthine (HYP) in millimolar levels
have been shown to inhibit maturation of cumulus-enclosed oocytes. To determine the effect …

Abstract Considerable evidence implicates cyclic 3′, 5′ adenosine monophosphate
(AMP) in the maintenance of meiotic arrest of mammalian oocytes. Since this laboratory …

Follicular fluid (FF) and oocytes were obtained from 19 women for in vitro fertilization.
Ovulation was induced with clomiphene citrate and human menopausal gonadotropin. Thirty …

Abstract cAMP, estradiol (E2), and progesterone levels were determined in 24 follicular fluid
samples obtained from 8 women who conceived after in vitro fertilization and in 47 samples …

The article by Wen and collaborators [1] published in the Metabolism entitled “High follicular
fluid adenosine levels may be pivotal in the metabolism and recycling of adenosine …

BACKGROUND: This study aimed to determine amino acid (AA), ammonia and urea
concentrations in human ovarian follicular fluid and to compare these concentrations with …

It is known that adenosine amplifies LH-stimulated cAMP accumulation and progesterone
production in rat luteal cells. The aim of this study was to investigate the effect of adenosine …

The purpose of the present study was to investigate the possible role of intrafollicular amino
acids in the human ovarian follicle. Follicular fluid (FF) and oocytes were obtained from 12 …

The concentrations of hypoxanthine and adenosine in ovarian follicular fluid were estimated,
using high-performance liquid chromatography, for three groups of mice: 1) pregnant mare's …
