Your Success Rates with NYCIVF
Fertility treatment success rate and especially IVF success can be measured using different outcomes.
We consider your IVF treatment successful when you are able to take home a single healthy baby. The safest and most successful method in achieving a single healthy baby is single blastocyst transfer.
Calculating the pregnancy rate per fresh egg retrieval encourages physicians and patients to transfer more than one embryo to increase the pregnancy rate. This substantially increases the chance of multiple pregnancies (30% for two embryo transfer, 1% for single embryo transfer).
Our approach to measuring IVF success
- We consider the cumulative pregnancies that are produced from one ovarian stimulation, one egg retrieval, one fresh embryo transfer and the transfers of frozen embryos till pregnancy ensues. This is because in the vast majority of cycles in women <39 years, undergoing their first IVF cycle, we transfer a single embryo. In subsequent frozen-Thaw cycles we also transfer a single embryo. This strategy will simply spread the chance for getting pregnant over 2-4 months, while markedly reduces the chance for twins and triplets. We transfer a single embryo in over 90% of patients < 39 years compared to a national single embryo transfer of <15% of cycles performed in The US. Our multiple pregnancy rate in last 12 months was 5.7%. Our patients’ cumulative pregnancy (from fresh and subsequent frozen embryo transfer from the same cycle) rates in women < 40 years is 78.6% in the last 12 months.
- Frozen Embryo Cycles. We use vitrification (fast freezing) to cryopreserve embryos which leads to higher survival compared to the older method of slow freezing. Also we commonly transfer thawed embryos back in natural cycles (minimal monitoring with no medication). This strategy in conducting frozen embryo transfer cycles make the transfer of thawed embryos efficient, very convenient with minimal intervention.
- We culture embryos to blastocysts (day 5 embryos) when feasible, aiming at increasing our ability to select the best embryo. Invasive methods for selecting the best embryo through embryo biopsy and PGD to tests embryos for chromosome makeup should not be routine at this time. PGD will not improve the cumulative potential to achieve a pregnancy if one considers all the embryos generated from a single cycle.
Individualization of IVF Treatment and Success Quotes
When we quote you success rates we include pregnancy rates and delivery rates for each proposed treatment and multiple pregnancy rates for each number of embryos to be transferred so that you are well informed of the potential benefits and risks. We then work together to individualize the strategy based on
- Female age
- Ovarian reserve markers
- Number of eggs retrieved and number and quality of available embryos on day 2 and 3
- Sperm source and condition (fresh, frozen, donor, surgically retrieved sperm)
- Other fertility factors (female weight, PCOS, endometriosis, uterine factor..)
- Other contemplated interventions e.g. sex selection, PGD for translocations..
