The use of kisspeptin-54 as an oocyte maturation trigger augmented expression of genes involved in ovarian steroidogenesis in human GL cells including, FSH receptor (FSHR), LH/hCG receptor (LHCGR), steroid acute regulatory protein (STAR), aromatase, estrogen receptors alpha and beta (ESR1, ESR2), 3-beta-hydroxysteroid dehydrogenase type 2 (3BHSD2) and inhibin A (INHBA), when compared to traditional maturation triggers, but did not alter markers of OHSS.
S1P had no effect on the expression levels of the enzymes 3β-hydroxysteroid dehydrogenase (3βHSD) or cholesterol side-chain cleavage enzyme (P450scc), but reduced the levels of steroidogenic acute regulatory protein (StAR) in OHSS rat ovaries (P < 0.05).
