The effects of high intracellular cAMP concentrations ([cAMP] i) on germinal vesicle
maintenance of bovine cumulus–oocyte complexes were investigated, using 8-bromo-3 …

A follicular spike in cyclic AMP (cAMP) and its subsequent degradation to AMP promotes
oocyte maturation and ovulation. In vitro matured (IVM) oocytes do not receive the cAMP …

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 …

We have recently reported that the adenylate cyclase activator, forskolin, induces in the rat
ovarian follicle both cAMP accumulation and oocyte maturation. We demonstrate here, on …

Cyclic adenosine monophosphate (cAMP) has been implicated as an important regulator of
meiotic maturation in mammalian oocytes. A decrease in cAMP, brought about by the action …

The intracellular levels of cAMP play a critical role in the meiotic arrest of mammalian
oocytes. However, it is debated whether this second messenger is produced endogenously …

It is known that dibutyryl cyclic AMP (dbcAMP) and theophylline inhibit the spontaneous
maturation of isolated mouse oocytes. The present study demonstrates that dbcAMP (0.01 …

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

We suggest that cAMP is a key molecule in regulation of oocyte maturation. In the small
follicle, tonic levels of cAMP are continuously transferred to the oocytes to maintain meiotic …

Bovine oocytes are arrested at the prophase of first meiotic cell cycle. Meiosis resumes in
oocytes of pre‐ovulatory follicles upon LH surge. However, oocytes from secondary follicles …
