Why eggs were preserved first
At 37, the patient had low ovarian reserve and an AMH result of 0.35 ng/mL. Her family circumstances meant that she was not ready for an immediate transfer. The agreed pathway was to retrieve and freeze eggs first, then proceed with later fertilization and embryo treatment.
From retrieval to warming
The stimulation plan used a mild approach for her ovarian findings. Five eggs were retrieved and vitrified. Two months later, the eggs were warmed and the laboratory continued the treatment sequence.

| Milestone | Recorded result |
|---|---|
| Eggs retrieved and frozen | 5 |
| Eggs surviving warming | 5 |
| Mature eggs that fertilized | 4 |
| Blastocysts developed | 3 |
| Embryos passing reported chromosome screening | 3 |
| Transfer | One embryo |
| Initial follow-up | Positive pregnancy test |
Why the stages are kept separate
Freezing preserved the eggs before embryos existed. Warming, maturity assessment, fertilization, blastocyst culture and chromosome screening were later steps. The successful warming result in this case did not remove the need for those further stages.
Follow-up milestone
The first pregnancy test after transfer was positive. The account ends with that early pregnancy result and does not document a later birth. Further pregnancy assessment is a separate stage of care.
