%X We present the spectral energy distributions (SEDs) of five massive young stellar objects (YSOs), detected from the NIR imaging survey carried out by Varricatt et al.[1] and estimated the physical and structural/geometrical parameters, including their ages and masses, for each of the five central YSO outflow candidates, along with their associated circumstellar disks and infalling envelopes. The SEDs of YSOs in five massive star forming regions has been reconstructed using 2MASS, MSX, IRAS, IRAC & MIPS, SCUBA, WISE, SPIRE and IRAM data, partly available from previous works, using the on-line SED Fitting tool developed by[2],[3]. We have derived the IRAS catalogue fluxes as well as the fluxes in the Mid-IR and sub-mm/mm, directly from the images. With the help of the analysis of SEDs and subsequently estimated parameters for the central YSO sources along with its circumstellar disks and envelopes, the cumulative distribution of the stellar ages and masses of the massive YSOs can be analysed. This leads to a better understanding for the formation history of massive stars in their respective star forming regions.
