No mature follicles at retrieval

Has anyone ever had this happen? I’ve gone through two rounds of IVF and each time we haven’t had any eggs mature when we do the retrieval. In both cycles we have had at least 6-8 eggs 18/19+ follicle size but still they aren’t maturing. The first time I did a trigger shot of Lupron & HCG. This time they just did HCG. My doctor is completely unsure of what may be causing it and is doing “research” says it’s really rare.

I’m now taking a break, focusing on losing weight and just ordered supplements of dhea & coq10. I do have low AMH but we are getting a decent amount of follicles and mature sized follicles but the eggs just aren’t mature. I feel so stuck. I’ve reached out to two other fertility clinics now to get second opinions but won’t have an answer on that for a few weeks.
