Brief Summary
Recent studies have shown that C natriuretic peptide (CNP) is produced from granulosa cells, increasing cumulative guanosine monophosphate (cGMP) production by affecting cumulus cells through natriuretic peptide receptors.It has been suggested that the transport of cGMP to oocyte via gap junctions causes a continuous increase in cyclic adenosine monophosphate (cAMP) levels within the oocyte. An important role of increased cAMP levels in oocyte is shown to suppress meiotic progression. Deoxyribonucleic acid (DNA) studies in animals have shown that expression of the natriuretic peptide precursor increases during the periovulatory period and shows that this increase decreases rapidly after Luteinizing hormone(LH) / human chorionic(hCG) stimulation. Human studies have shown that after ovulation induction, the CNP level in follicular fluid decreases following ovulatory dose of hCG (9).

Limitations and Caveats
The most prominent limitation of our study was the relatively small number of participants. This avoided us from using more powerful parametric tests for statistical analysis.
