The aim of the present study was to measure the level of cyclic GMP (cGMP) compared with
the level of cyclic AMP (cAMP) in rat oocytes during resumption of meiosis I (oocyte …

The influence of cyclic nucleotides on meiosis in isolated rat oocytes was studied. It is known
that dbcAMP inhibits the spontaneous maturation of isolated rat oocytes. However, the effect …

Oocyte cumulus complexes (OCC) were isolated from antral follicles of proestrous hamsters
prior to the luteinizing hormone (LH)/follicle-stimulating hormone (FSH) surge and then …

Recent work on the mouse is discussed. The results support the view that cAMP participates
in the maintenance of meiotic arrest, and that purines may help sustain meiosis-arresting …

We report the results of experiments which support the hypothesis that, in mouse oocytes, a
decrease in intraoocyte cyclic AMP (cAMP) initiates meiotic maturation; oocytes …

Mouse oocytes are reversibly inhibited from resuming meiotic maturation in vitro by cAMP
phosphodiesterase inhibitors such as 3-isobutyl-1-methyl xanthine (IBMX) and cAMP …

The effect of increasing cytoplasmic calcium on cyclic adenosine monophosphate (cAMP)‐
dependent meiotic arrest (% GV where GV is germinal vesicle) in hamster oocytes was …

The effects of follicle-stimulating hormone (FSH) and cyclic guanosine 3′, 5′-
monophosphate (cGMP) on spontaneous oocyte maturation and cyclic adenosine 3′, 5 …

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 …

The involvement of cyclic adenosine monophosphate (cAMP) in mammalian oocyte
maturation was assessed using cultures of rabbit cumulus–oocyte complexes and perfused …
