Perhaps you should try some spelling variations:
decreases ovarian » decreases organ (Expand search), decreases cardiac (Expand search), decreases pain (Expand search)
ovarian patterns » varied patterns (Expand search), variation patterns (Expand search), location patterns (Expand search)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
decrease low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (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 AND decrease low decrease ) OR ( decrease toc decreases ovarian patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease low decrease ) OR ( decrease toc decreases ovarian patterns ))*.
