Mainline Fertility was my first RE. I moved on to Penn and conceived my OE DD. 4 years later and after trying our best with OE at Cooper - I have an appt at Mainline next week. They are developing a new program similar to RBA. My initial visit next week is to get started on HRT. But I plan to keep the door wide open to DE for the summer/fall. I liked Dr. Orris (younger of the 3 doctors).
