Abstract—Obesity is a crucial health issue, being a risk factor for the development of chronic metabolic diseases such as type 2 diabetes, hypertension, hyperlipidemia, cardiovascular diseases, and some types of cancer. Traditional methods to control obesity by decreasing food intake, increasing exercise, and medical interventions have not been successful and more fundamental knowledge at the level of genes is required. In men, low levels of testosterone have emerged as an important medical concern since testosterone deficiency is related to the development central obesity. White fat cells were grown in DMEM supplemented with 10% FBS. Lipid accumulation in 3T3-L1 adipocytes was assessed by staining for 1hr in a freshly diluted Oil Red O. RNA was extracted, cDNA synthesised and mRNA quantified using standard qRTPCR. 3T3-L1 treated with sex steroids (5, 15, 30 nM) for 13 days exhibited a non-significant decreased in adipogenic markers (Resistin and FABP 4) without clear change in Adipo Q expression. Conclusion Adipogenic markers were not affected by steroid hormones, and These data demonstrate the need to conduct more results to investigate the effect of sex steroid at different doses and  time courses especially during early stage of differentiation on transcription factors such as PPAR gamma 2, CEBP alpha, and CEBP betta.
