Dr. Amos Madanes
One of the few board-certified reproductive endocrinologists in Illinois, Dr. Amos Madanes has been helping infertile couples since 1979. Over the course of his career, he has developed several revolutionary assisted-reproduction procedures and has thus, come to be internationally known as an innovator and leader in the field of reproductive endocrinology. In fact, he is responsible for the first pregnancy ever in the United States from a non-surgical intra-tubal insemination procedure. The incredible results of this technique have brought new hope to couples, particularly those dealing with male-factor infertility.
Dr. Madanes earned his Doctor of Medicine degree from Tel Aviv University in Israel. After completing specialty training at Tufts University in Boston, he underwent two additional years of reproductive endocrinology training at Harvard University School of Medicine and Tufts.
