Perhaps you should try some spelling variations:
decreased within » decreased with (Expand search), decreases with (Expand search), decrease with (Expand search)
within progenies » sibling progenies (Expand search), in progenies (Expand search), their progenies (Expand search)
life decreased » life decreases (Expand search), with decreased (Expand search), is decreased (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease life decreased within progenies ) OR ( decrease OR decrease the decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease life decreased within progenies ) OR ( decrease OR decrease the decrease ))*.
