Owens et al. (26) found no difference in the transcription of the AMH gene or its receptor in their study which compared the expression of 13 genes by quantitative RT-PCR by GCs from small, unstimulated antral follicles (on ovarian cortex sampled for fertility preservation) and on partially luteinized GCs (in patients benefiting from in vitro fertilization) in women with PCOS vs. control women. The gene discussed is AMH; the disease is polycystic ovary syndrome.
