Mature Eggs and follicle sizes
I’m a 39 F- Has anyone figured out what follicle sizes actually give them mature eggs? I’m trying to optimize maturity for future IVF cycles and feeling confused because my results seem all over the place.
In my first retrieval, at trigger I had follicles around 21, 12, and 13 mm. They got 3 eggs total, and 2 were mature at retrieval. The third matured later through IVM. I sadly got not blasts. My trigger that cycle was 5,000 hCG and lupron
In my second retrieval, I had follicles measuring about 18, 17, 16, 16, 15, 14, and 12 mm. They retrieved 5 eggs, and 3 were mature. This time my trigger was actually much stronger (15,000 hCG) with lupron.
I stimmed for 9 days for cycle 1 and 13 days for cycle 2
The good news is that the 3 mature eggs all fertilized and ended up giving me 2 blasts, which I’m really grateful for. But I’m trying to figure out how to maximize the number of mature eggs next cycle so I have more chances at getting blasts.
Has anyone noticed that their eggs only tend to be mature at certain follicle sizes? Did changing your trigger timing, trigger dose, or waiting an extra day help improve maturity?
It just feels like maturity is so variable from cycle to cycle, and I’m wondering if there’s a way to figure out what my “sweet spot” is. Would love to hear if anyone has had a similar experiences and what helped!
