▲ 1 r/DOR
First IVF cycle: 5 retrieved, only 2 mature despite 21–26mm follicles — protocol/timing issue?
36F with DOR looking for feedback on first IVF cycle, especially the low maturity rate.
Background:
- AMH has ranged from ~0.6–0.85
- FSH 7.8
- AFC usually around 10–12
- stage 1 endometriosis treated via laparoscopy in July 2025 (not on ovaries)
- 5 prior medicated IUIs (no trigger) before moving to IVF
Round 1 protocol:
Priming:
- 35 days estradiol 6mg
- 15 days Prometrium suppositories 200mg
Stims (13 days):
- Clomid 100mg
- Follistim 250
- Menopur 225
Suppression:
- Ganirelix 250mcg started stim day 10
Trigger:
- Pregnyl 10,000 units on day 13
Monitoring/labs:
Baseline:
- E2 18
- Progesterone 2.5
- AFC ~10–12
Day 6 of stims:
- E2 66.9
- Progesterone 0.4
- LH 6.4
- Around 6 follicles, all 9mm or smaller - doctor said they were growing very slowly
Day 12 of stims:
- E2 1154
- Progesterone 0.6
- LH 5.4
- 3–4 follicles on right, 1 on left - sizes 18–21mm
Trigger day:
- E2 1782
- Progesterone 1.0
- LH 5.8
- 3–4 follicles on right, 1 on left - sizes 21–26mm
Retrieval:
- Retrieval on day 15
- 5 eggs retrieved
- Only 2/5 were mature and able to be ICSI’d
- Both fertilized normally (2PN day 1)
I’m mainly trying to understand:
- Does 2/5 mature seem unusually low given these follicle sizes/E2?
- Could trigger timing have been off?
- Does anything about this protocol stand out as potentially over-suppressive or not ideal for DOR?
- Has anyone had significantly better maturity in later rounds after protocol changes?
TYIA!
