In Half The Sky, Nicholas D. Kristof and Sheryl WuDunn tell the inspiring story of Saima Muhammad in Pakistan who was able pull her family out of poverty and become a prosperous woman after receiving a $65 loan from a microfinance organization.  I have donated to Kiva for several years now (kiva.org) and specifically searched out opportunities to donate to women.  After reading about Saima, I became curious of other microfinance organizations.  How do they rank?  What is their mission? etc.  I found some helpful information at myphilanthropedia.org.
