Looking beyond the initial ovarian-reserve result
The patient was 37 and had an AMH result of 4.36 ng/mL. Two previous stimulation cycles had produced eggs but no embryos passing the reported chromosome screening. The reason for review was therefore not simply the number of eggs available.
The earlier laboratory sequence
The first earlier retrieval yielded 20 eggs, of which 13 were mature and four fertilized. In the second earlier retrieval, eleven eggs were obtained, seven were mature and two fertilized. The reported screening outcome in each cycle was zero embryos passing.
The INCITA team considered follicle development, hormone monitoring, trigger and retrieval timing when planning another cycle.

| Stage | Earlier cycle 1 | Earlier cycle 2 | INCITA cycle |
|---|---|---|---|
| Eggs retrieved | 20 | 11 | 19 |
| Mature eggs | 13 | 7 | 13 |
| Fertilized eggs | 4 | 2 | 13 |
| Blastocysts | 2 lower-graded blastocysts reported | 2 lower-graded blastocysts reported | 10 |
| Embryos passing screening | 0 | 0 | 7 |
The reported embryo findings
The INCITA cycle produced seven embryos passing the reported screening. Their grades were recorded as two 6AA, two 5AA, one 5BA, one 6BB and one 4BB. Grading describes observed embryo development and is considered separately from the chromosome result.
Stage reached
At the time of the account, the patient was preparing the endometrium for transfer. The reported milestone is embryo development and screening; a later pregnancy or birth is not added to this history.
For similar reviews, keep the complete egg-maturity, fertilization and embryo-culture records with the previous screening reports. See reading laboratory results and reviewing earlier treatment.
