<prompt> Oxytocin causes all except -LactogenesisMilk ejectionContraction of uterine muscleMyoepithelial cell contraction  <response>: Ans. is a i.e., Lactogenesis Impoant actions of oxvtocin are : Contraction of uterine smooth muscle directly by acting on GPCR and indirectly by release of PG and LTs.
