The administration of cabergoline did not reverse the significant decrease in TRPC1 gene expression that was observed as a result of OHSS exposure (G1 vs. G2; p = 0.009), while the administration of nifedipine significantly increased TRPC1 expression in comparison to G2 and G3 (p = 0.007 and p = 0.008). The gene discussed is TRPC1; the disease is ovarian hyperstimulation syndrome.
