Viviparous
Definition:
(a.) Producing young in a living state, as most mammals, or as those plants the offspring of which are produced alive, either by bulbs instead of seeds, or by the seeds themselves germinating on the plant, instead of falling, as they usually do; -- opposed to oviparous.
Example Sentences:

(3) Based on in vivo and in vitro modulation of immune responses by placental products, it is concluded that: 1) allograft enhancement and high production of IgG1 antibodies are not linked to the same glycoprotein, 2) the immunomodulators in relation to the protection of viviparity appear to be located at the exclusion limits of Sephacryl S-200 (i.e.
