Effect of Calcium on the Stability of the Vitelline Envelope of Surf Clam Oocytes.
TLDR
It is demonstrated that hypertonic conditions induce the oocytes to undergo NEBD in the absence of extracellular calcium, and suggest that the function of calcium may be to maintain the oocyte surface in a fertilization-competent state, while the reactions subsequent to the initial activation event, and leading to nuclear envelope breakdown (NEBD), may not require calcium.

TLDR
The results suggest that nuclear disintegration and the meiotic process induced by sperm are mediated by ionic stimuli and that the establishment of meiotic arrest is linked to the availability of calcium within the oocyte.

TLDR
The results suggest that hormones cause ionic alterations in oocytes and that ions are directly involved in the activation response, and suggest that oocytes exposed to steroid over part of their surface do not respond, with regard to nuclear breakdown, in the same manner as do oocyte exposed over their entire surface to similar concentrations of steroid.
Effect of testosterone and dibutyryl cAMP on the spontaneous maturation of pig oocytes.
TLDR
The results suggest that the cumulus cell mediated the inhibitory action of testosterone and dibutyryl cAMP on the maturation of the intact oocyte, and suggest that oestrogen may be implicated in the observed inhibition of oocyte maturation.
ON THE ROLE OF CALCIUM IONS IN OOCYTE MATURATION IN THE POLYCHAETE CHAETOPTERUS PERGAMENTACEUS *
TLDR
The role of calcium in oocyte maturation was established and its importance was discussed based on the results obtained with the different ways of inducing oocytes maturation.
