Neupogen is a drug that causes the body to generate neutrophils, a type of white blood cell which plays an important role in the immune system. Our clinic has investigated its use in fertility treatment as a solution to certain immunologic causes of multiple miscarriages. It has often proven successful when other options have failed. You may benefit from using Neupogen if you have experienced recurrent miscarriages after failed IVIG or LIT and if you meet specific criteria for treatment. The drug is also useful in many cases for the purpose of improving egg quality or improving the tissues of the uterine lining. Our clinic has the LARGEST NUMBER of patients in the country that have been treated with Neupogen for failure to initiate and complete a pregnancy. It is critical that your treating physician has vast experience with the use of this drug for fertility.
