High oocyte targets may require multiple stimulation cycles.
Population estimate, not an individual prediction. Personal assessment with your specialist is essential.
Assumptions: oocyte maturity ~80%, retrieval rate ~70% of follicles >11mm.

What is my
gestational age today?
For pregnancies conceived through IVF, gestational age is computed from the embryo transfer date and the embryo age on the day of transfer.
“IVF dating is the most accurate dating in obstetrics — the date of conception is known to the day.”

Cumulative probability of live birth
Complete cycle = one retrieval plus all fresh and frozen embryo transfers arising from it.
Sources: McLernon DJ et al. BMJ 2016;355:i5735 (pretreatment model from 113,873 women, 1999–2008). UK OPIS calculator (w3.abdn.ac.uk/clsm/opis/) implements the same model.
Cumulative live birth probability over up to five transfers (following PGT-A).
Cumulative live birth probability from chromosomally normal embryos
Per-transfer rates were stable across ages 25–42 in the published series — once you have a chromosomally normal embryo, the live-birth probability per transfer is largely age-independent.
Sources: Pirtea P et al., Fertil Steril 2021;115:45–53 (n=4,429, up to 3 transfers). Gill P et al., Hum Reprod 2024;39:974–980 (n=123,987, up to 5 transfers).

Patient stories
Three different paths. Every story unique.
Single mother through PGT-A
“At 43 I decided to become a mother on my own. After two unsuccessful attempts at other centres, PGT-A identified a chromosomally normal embryo. My daughter is one year old today.”
M., Thessaloniki
After recurrent miscarriage
“We had lost three pregnancies before we reached this clinic. Prof. Kolibianakis explained what changes with chromosomally normal embryo transfer. Today we hold our son in our arms.”
S. & D., Katerini
Fertility preserved before chemotherapy
“Seven years ago I froze my eggs just before chemotherapy. I returned after recovery and within ten months I was holding my twins. I had never imagined it that clearly.”
E., Athens
