<p>Fetal growth is promoted, and fetal growth retardation is reduced, in mammals by increasing in a maternal host during pregnancy the active concentration of IGF-1 and/or IGF-2 and/or analogues thereof. The active concentration of IGF-1 and/or IGF-2 and/or analogues thereof may be increased by administering such a compound to the maternal host, or by administering to the maternal host a compound, such as placental lactogen, which upon being so administered increases the active concentration of IGF-1 and/or IGF-2 and/or analogues thereof in the maternal host.</p> |
