SwissAtlas provides structured, non-medical coordination with private Swiss clinics for international patients, ensuring discretion and clarity.
SwissAtlas supports international families navigating complex medical situations with discretion and clarity. Each case is handled with strict confidentiality and a structured coordination approach. Designed for sensitive situations requiring discretion and clarity.
Switzerland offers rigorous regulatory oversight, strong privacy protections, and personalised care.
SwissAtlas coordinates the administrative and logistical layer only. We do not provide diagnosis, treatment, or medical recommendations. We facilitate confidential intake, neutral clinic matching, communication governance, and documentation support.
IVF success rates reported by Swiss clinics and national registries reflect cohort-level averages that depend heavily on patient age distribution, indication mix, and the denominator used. Clinics that report "per transfer" success rates will show different numbers than those reporting "per cycle started" or "per egg retrieval" — with the same underlying clinical performance. Families should always ask which denominator applies before comparing figures across institutions or countries.
IVF outcome statistics in Switzerland are recorded through the FIVNAT Swiss IVF registry, the national registry for assisted reproduction data.
Age is the dominant variable in autologous IVF outcomes. Live birth rates per transfer using own eggs decline substantially from the mid-30s onward and fall sharply above 40. A clinic reporting a 45% live birth rate is almost certainly reporting outcomes for patients under 35. Families over 38 planning autologous IVF should request age-stratified data specific to their age group, not programme averages.
For patients under 35 using own eggs, Swiss private clinics with active IVF programmes typically report per-transfer live birth rates in the 40–55% range for fresh or tested-frozen transfers in well-selected cohorts. These figures align with published FIVNAT national registry data and European benchmarks. They decline progressively with age: per-transfer live birth rates for patients 38–40 are typically 25–35%; for patients over 42 using own eggs, figures below 10% per transfer are common.
Donor oocyte cycles show more stable outcome profiles across recipient ages because the oocyte quality variable is controlled. Per-transfer live birth rates in donor cycles at Swiss programmes are typically 45–60% when recipient endometrial preparation is optimised. These figures are relatively consistent across recipient ages, which is why donor oocyte cycles are often recommended when autologous egg quality is the limiting factor.
Preimplantation genetic testing for aneuploidy (PGT-A) removes chromosomally abnormal embryos from the transfer pool. In programmes with high PGT-A uptake, per-transfer success rates appear higher because only euploid embryos are transferred — but cumulative success rates per stimulation cycle may be similar to those of unscreened programmes once abandoned cycles (no euploid embryos produced) are included. Families evaluating PGT-A programmes should request both per-transfer and per-stimulation-cycle data to understand the true denominator effect.
The most useful pre-commitment questions are: what are your live birth rates per transfer for my age group using own eggs in the last reported calendar year; what percentage of your cycles are cancelled before retrieval; what is your blastulation rate; and what is your euploid embryo rate per retrieval in my age group if PGT-A is part of the protocol. These four questions — together with honest answers — give a more accurate programme profile than any headline figure a clinic publishes on its website.
SwissAtlas operates exclusively as a non-medical coordination platform. We do not provide clinical services, diagnoses, or treatment recommendations. All medical decisions are made by licensed Swiss institutions.
ESHRE cumulative live birth rates per retrieval by maternal age: under 35 years approximately 35–45%; 35–37 years 25–35%; 38–40 years 15–25%; above 40 years 8–15%. These cumulative figures include all transfers from a single retrieval, including frozen-thawed cycles. Per-transfer rates are consistently lower and are the figure most commonly cited in clinic marketing materials — the distinction matters when comparing centres.
Egg donation success rates are substantially higher and age-independent for the recipient: approximately 45–55% per transfer, reflecting the use of oocytes from donors under 33. The main variable on the recipient side is endometrial quality. Families comparing IVF options should request cumulative live birth rates per retrieval stratified by maternal age — not headline per-transfer figures from unspecified cohorts.
Comparing IVF success rates across clinics requires consistent methodology. Clinics that report per-transfer rates from optimal subgroups — selected embryos, younger patients, single transfers — will show higher figures than those reporting all-comers cumulative data. When requesting statistics from a Swiss clinic, ask specifically for cumulative live birth rate per oocyte retrieval, stratified by maternal age, across all patients treated in the last two calendar years. This removes selection bias from the comparison.
Frozen embryo transfer cycles now account for the majority of transfers in high-quality Swiss programmes, because freezing all embryos and transferring in a subsequent natural cycle consistently shows higher implantation rates than fresh transfer in stimulated cycles. Families should ask what proportion of cycles use a freeze-all strategy and what the frozen transfer live birth rate is separately from fresh.
One additional variable that is rarely volunteered: laboratory quality. The embryology laboratory — its air quality systems, culture media, time-lapse incubator availability, and vitrification protocols — directly determines embryo survival rates. A clinic with strong clinical protocols but a lower-quality laboratory will underperform relative to its patient profile. Asking to see laboratory accreditation and freezing survival rates is a legitimate and useful question.
SwissAtlas does not present or compare clinic success rates. What the coordination layer contributes is ensuring that the file presented to a Swiss fertility centre is complete, that the right questions are asked at the first consultation, and that families understand what the statistics they are given actually measure before making a cycle decision.
SwissAtlas supports families in formulating the specific questions that extract meaningful outcome data from Swiss fertility centres — cumulative live birth rate per retrieval, stratified by age, across all comers — rather than the headline figures that are optimised for marketing rather than decision-making. Understanding what a success rate actually measures is the prerequisite for using it correctly.
SwissAtlas coordinates non-clinical sequencing, documentation flow, and logistics governance while licensed institutions retain medical decision authority.
Records should be assembled as chronology with unresolved questions so specialist review can proceed without avoidable interpretation gaps.
Budgets should be scenario-based because pathway scope can evolve after deeper institutional evidence review.
Confidentiality is strengthened by role-based recipient controls and approved channels defined before high-sensitivity updates begin.
Timelines are safer when logistics commitments are tied to confirmed milestones rather than assumptions made before candidacy is established.
Confidential access to private medical care in Switzerland.
SwissAtlas operates at the intersection of discretion, structure, and access. Unlike traditional intermediaries, we do not promote specific clinics or treatments. Our role is to provide a neutral, structured, and confidential coordination layer for international patients navigating complex medical situations. This approach allows families to move forward with clarity, without pressure, and without exposure.
SwissAtlas is designed for: international families seeking discretion; patients requiring fast and structured access; situations where clarity and confidentiality are essential.
No medical advice. No pressure. Only structured coordination.
