Is it common for follicles to grow at uneven rates during an IVF cycle? (Ask the Egg Whisperer)

Recently, Carrie wrote in to Ask The Egg Whisperer with a question. Here's what she she said, "Hi Dr. Aimee, Thanks for the incredible support you bring our community. I'm 39 and just had my first IVF cycle. AMH is 1.67. On day 9, they counted 25 follicles, but only 8 follicles measured above 11 mm. My protocol was "spontaneous antagonist." I'm feeling really discouraged that my follicles didn't grow in a more synchronized fashion. Is this common and is there anything I can do next time? I can't help but feel the remaining follicles that measured too small were just a waste." This can happen, and eight follicles is still pretty great. I share my thoughts about possible endometriosis and adenomyosis with Carrie. You can hear the whole explanation in this episode. Tune in to hear my full answer, and the answer to 9 other questions.
