Talvez deva tentar algumas variações de ortografia:
decreased sperm » decreased sleep (Expandir a busca)
sperm decrease » term decrease (Expandir a busca), speed decrease (Expandir a busca), speed decreases (Expandir a busca)
methods python » methods action (Expandir a busca), pythons python (Expandir a busca), methods method (Expandir a busca)
use processes » cure processes (Expandir a busca), dose processes (Expandir a busca), use process (Expandir a busca)
decrease use » decreased use (Expandir a busca), decrease the (Expandir a busca), increase use (Expandir a busca)
python and » python based (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decreased sperm decrease use processes ) OR ( python and methods python programming ))~.
