The germinal vesicle (GV) of follicle-enclosed oocytes in mammals remains arrested at the
dictyate state of meiosis. Upon releasing the oocytes from the follicles, the meiotic process …

The nature and functions of the chemical signals involved in the acquisition of competence
to resume meiosis, and the maintenance of meiotic arrest in antral follicles are the subjects …

The objective of this study was to compare the cAMP and cGMP levels in cumulus-oocyte
complexes (COCs) derived from the middle follicles (MFs, 3− 6 mm in diameter) and small …

This study investigated further our previous finding that testosterone synergizes with
dibutyryl cyclic AMP (dbcAMP) to arrest the meiosis of a very high proportion of cumulus …

ABSTRACT Cyclic adenosine 3'-5'monophosphate (cAMP) acts as a second messenger for
various pituitary hormones. The mode of involvement of cAMP in the regulation of meiotic …

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

The present study was undertaken to assess the role of alterations of intraoocyte cAMP
concentrations in the meiotic maturation of isolated and follicle-enclosed oocytes. In isolated …

Cytogenetic data are presented which indicate species differences in the response of
oocytes maturing in vitro in the presence of dibutyryl cyclic AMP (dbcAMP). Inhibition of ewe …

Cyclic AMP (cAMP) is a second messenger that plays a critical role in follicular recruitment,
development and luteinization in the mammalian ovary. The cellular level of cAMP is largely …

The cyclic adenosine monophosphate (cAMP) content of intact oocyte‐cumulus cell
complexes at various times after the induction of oocyte maturation in mice in vivo was …
