SOHLH2 and gestational diabetes: To further confirm the effects in primordial follicle formation caused by gestational diabetes, the mRNA of oocyte specific genes such as LIM homeobox 8 (Lhx8), newborn ovary homeobox (Nobox), spermatogenesis and oogenesis helix-loop-helix (Sohlh2), and factor in the germline alpha (Figlα) were examined in ovaries of neonatal offspring at PND 1.
