Understanding Oocyte Retrieval: A Journey Through Follicles 🌸
I had ten follicles and ended up with four mature eggs. Ever wonder why? 🤔 Let's dive into the fascinating world of follicle-to-oocyte retrieval efficiency!
🔍 The relationship between antral follicles and retrieved oocytes varies greatly among individuals. Here’s a quick breakdown:
- **Baseline AFC to mature oocyte ratio:** Generally, expect about one mature oocyte for every four antral follicles. For example:
- 8-10 antral follicles → expect 2-3 mature oocytes
- 12-16 antral follicles → expect 3-5 mature oocytes
- 20-24 antral follicles → expect 5-7 mature oocytes
- **Stimulated follicle to oocyte ratio:** On trigger day, for follicles ≥16 mm, the retrieval rate is about 100-105%! However, for those ≥12 mm, it drops to around 60-80%.
