Our results revealed the potentially important roles of genes related to cellular development, connective tissue development and function, inflammatory and immune response, cellular growth and proliferation, and reproductive system development and function, including genes such as FOXP1, FOXO1, DCN, IL33, INSR, KLF2, PAPPA, VIM, and ZFP36, that have significant gene expression changes in the OHSS group compared to PCOS patients [24,25,26]. Here, PAPPA is linked to polycystic ovary syndrome.
