The pure virile semen (shukra)is unctuous (snigdha),  viscous (ghana), slimy (picchila), sweet (madhura). It does not cause burning sensation in genital tract (avidahi).  It looks like white crystal quartz (shukla).[Cha. Sa.[[Chikitsa Sthana]] 30/146]

During metabolism, the unctuous part of predecessor [[majja dhatu]] is transformed into shukra dhatu. The marrow is present in bones. Minute pores are created by the action of [[vayu]] and [[akasha mahabhuta]] on bones. The shukra dhatu oozes out from these minute pores after action of factors responsible for the metabolism of shukra dhatu (shukra dhatu agni).  This process is like water oozing out of new mud pot, shukra also oozes out of these pores. It is then circulated all over the body through channels of transportation of shukra dhatu(shukravahasrotas).[Cha. Sa.[[Chikitsa Sthana]] 15/32-33]

Ayurveda text describe the formation of shukra dhatu from majja dhatu. Current research shows that bone marrow-derived mesenchymal stem cells (BM-MSCs) have the potential for differentiation. They secrete anti-inflammatory cytokines and growth factors which make them appropriate for cell therapy. A study conducted to evaluate the healing effect of BM-MSCs transplantation on germinal cells showed that the transplanted BM-MSCs could successfully induce spermatogenesis in seminiferous tubules of azoospermic hamster. Therefore, BM-MSCs can be an attractive candidate in cell transplantation of azoospermia.<ref> Tamadon A et al, Induction of Spermatogenesis by Bone Marrow-derived Mesenchymal Stem Cells in Busulfan-induced Azoospermia in Hamster,Int J Stem Cells. 2015 Nov;8(2):134-45. doi: 10.15283/ijsc.2015.8.2.134</ref>
