text: Dr Sher is a pioneer in fertility. He does a simple immunologic test that identified the likely reason why my 4 previous IVF attempts had failed. Both the test and solution are simple and inexpensive, so why other fertility doctors do not do it is a mystery. I am so glad I didn't waste any more money anywhere else! Dr Sher is also the pioneer of using Viagra to treat thin uterine lining which also contributed to my success getting pregnant on my first attempt with him. \n\nThe fact that Sher Institute constantly breaks ground and leads the way in fertility contributed to my 5 star scoring, but the BEST PART of my experience was Dr Sher himself (and his staff).  He genuinely cares about his patients. He took the time to get to know me. I felt like his favorite patient  (but I suspect he makes everyone feel that way) From our very first phone consultation, he has encouraged me to call his CELL PHONE with any questions...When was the last time you were given a doctors cell number?...I highly recommend Dr. Sher. In fact the entire staff was great at the Sher institute, Las Vegas.
