I have recently been diagnosed with an ovarian dermoid cyst. while usually slow growing, this one became 5 cm in 6 months. i also struggle with infertility. should i operate it and then proceed with clomid iui? or can i do the treatment first?

The best person to give this advice is your Gyn who knows you best. You can choose either. Good luck.

Complex ovarian cysts, including "dermoid cysts" are usually needful of biopsy and/or removal, especially at "age 34". See your GYN physician for guidance, and obtain a later appointment with a reproductive endocrinology physician for fertility treatments.
