In the introduction, " A report on 23 women with primary ovarian insufficiency has shown that PRP could be a proper treatment option for these patients." should be changed to " A report on 23 women (of 311) with primary ovarian insufficiency who conceived spontaneously has shown that PRP could be a proper treatment option for these patients." The other one is that the reference number 23 (Sills ES, Rick- ers NS, Li X, Palermo GD.
