Endometriosis is a common and benign angiogenesisdependent gynecological disorder,which refers to the proliferation and growth of endometrium-like tissues with neovasculature formation outside of the uterus.1 Available medical treatments for endometriosis containing hormonal and non-hormonal treatments had been limited for longterm usage by their side effects.2 Ideal medical treatment for endometriosis with efficacy to relieve symptoms and suppress endometriotic lesion growth and minimal side effects has been longing for decades.3 Angiogenesis is a promising therapeutic target for endometriosis.
