The choice to undergo IVF treatment is a decision many women and couples make with the hope of a successful outcome. For a prime candidate in the majority of programs, transferring one blastocyst will yield over an almost 50% pregnancy rate in women under the age of 35. For other candidates, SART (in conjunction with The American Society for Reproductive Medicine) has published guidelines on the recommended number of embryos to transfer based on specific patient characteristics, like age and history.

From our 2015-2018 cumulative:
- There were 981 fresh autologous IVF cycles (cycle starts or intended retrievals) in women under 35, resulting in 412 live births, 26 of the cycles were cancelled and 19 retrievals did not result in an embryo transfer. 42 % live births (LB) per cycles start (intended retrievals); 43 % LB per retrievals, and 44% LB per transfer.
- There were 735 fresh autologous IVF cycles (cycle starts or intended retrievals) in women 35-37, resulting in 221 live births, 17 of the cycles were cancelled and 6 retrievals did not result in an embryo transfer. 30% live births (LB) per cycles start (intended retrievals); 31 % LB per retrievals, and 32% LB per transfer.
- There were 1225 fresh autologous IVF cycles (cycle starts or intended retrievals) in women 38-40, resulting in 221 live births, 60 of the cycles were cancelled and 19 retrievals did not result in an embryo transfer. 18 % live births (LB) per cycles start (intended retrievals); 19 % LB per retrievals, and 20% LB per transfer.
- There were 1143 fresh autologous IVF cycles (cycle starts or intended retrievals) in women 41-42, resulting in 111 live births, 89 of the cycles were cancelled and 60 retrievals did not result in an embryo transfer. 9.7% live births (LB) per cycles start (intended retrievals); 10.5 % LB per retrievals, and 11.1% LB per transfer.
We are proud of our IVF success rates. However, we encourage patients to use other types of criteria when comparing treatment centers because there are a number of variables involved in successful IVF treatment. Most important to note is that:
- Our philosophy of clinical management is to not restrict poor responders and failed prior cycle patients from entering into their IVF programs (allowing them access to donor egg cycles only)
- Success rates decline as women age, especially after the mid-thirties
- Patient characteristics and entrance criteria vary widely among programs
After age 35 the success rates for IVF naturally decrease. Part of this decline is due to a lower chance of getting pregnant from ART, and part of it is due to a higher risk of miscarriage with increasing age (especially over age 40) which reflects the natural deterioration of the genetic integrity of the embryo with age. If patients require several cycles of treatment to have a baby, the success rates may also remain fairly constant over several cycles but may vary greatly between individual patients.
Advanced technology and uniformity in commercially available culture media has allowed all IVF treatment programs to reach optimal success rates.
Our Success Rates YR 2015-2018 for (Non-Frozen) Fresh IVF Cycles (Non-Tested PGT-A Embryos)
| % Cycles Liveborn | % Retievals Live Born | % ET Liveborn | % Cancellations | |
|---|---|---|---|---|
| Under 35 | 42 | 43 | 44 | 2.6 |
| 35-37 | 30 | 31 | 31 | 2.3 |
| 38-40 | 18 | 19 | 20 | 4.9 |
| 41-42 | 9.7 | 10.5 | 11.1 | 7.8 |

Please note: A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches, and entry criteria (FSH, AMH) for ART may vary from clinic to clinic. The data presented above are for fresh non-frozen embryo transfers without PGT-A (pre-implantation genetic testing for aneuploidy ). National data, as well as our data, do confirm that clinical pregnancy rates after frozen thaw blastocyst transfer with screened normal genetic embryos approaches 70% regardless of age and the delivery rate over 60%. This service is available at CFNYC.
As an example, there were 86 frozen embryo transfers at Chelsea Fertility NYC in 2018 with 46 liveborn. 35 deliveries for 58 embryo transfers of normal embryos by PGT-A; and 11 deliveries in 28 embryo transfers without any PGT-A testing.
