As pioneers in the field of infertility, our staff has published over 600 articles in peer reviewed journals.  Below are these articles separated by infertility topic.  There is also a group of summary editorials that review many of our innovative findings and illustrate our philosophy of diagnosis and treatment.  Please note: we will update these articles annually.
