Dear Dr. Sher,

I am 43 years old and am trying for the last time, after five unsuccessful attempts (I have reached the euploid stage before).

This time I have 9 antral follicles, but I also have a follicular cyst. It is regressing: four days ago it was 15mm and today it’s 12mm. My period started yesterday, and I have been taking estradiol for 10 days. I haven’t started FSH, and my doctor wants to reassess in another 4 days.

My question is: if the cyst is still there, for example at 10mm, should I proceed with this cycle? What is the risk to my ovary? Will the cyst hinder the growth of the other oocytes? Should I go ahead or postpone to the next cycle, despite my age?

Thanks again for being so kind and sharing your wisdom with us all.

Anne
