time in women with infertility

Reviewer's report:
The authors have made some essential revisions on the previous manuscript that
has greatly improved on its quality. I also have some minor comments regarding
the revised copy of the manuscript. 
On line 52 of the methods section, part of the sentence reads "tourniquet 5-10 cm
on the elbow". Is it not supposed to be above the elbow?
On line 21 of the discussion section, I don't think the serum hormones were
analyzed with respect to infertility cause.
On lines 29-32 of the discussion, the sentence is not clearly written. Please
consider rephrasing it.
I believe these comments are critical and should be addressed by the authors.
