1. IVF nascence rates take increased for patients nether 43 years
About 54,000 patients had 68,724 fresh and frozen in-vitro fecundation (IVF) cycles and 5,651 donor insemination (DI) cycles at HFEA licensed fertility clinics in the U.k. in 2018. Later years of rapid growth in the number of treatment cycles, these have begun to stabilise.
Birth rates from IVF have steadily increased over fourth dimension with the average nativity rate per embryo transferred at 23% in 2018. Patients under 35 had the highest nascence rate per embryo transferred at 31% in 2018, compared to just ix% when the HFEA was established in 1991.
The average age of an IVF patient was 35.3 years in 2018; age is a central factor to consider when looking at nascence rates, as fertility decreases with age. In 2018, nativity rates per embryo transferred were 25% for patients aged 35-37, 19% for patients aged 38-39, and 11% for patients anile xl-42.
Clinical improvements have led to increased chances of a live birth for all patients below 43 years old. In 2018, patients aged 40-42 had a higher chance of a live birth (xi% per embryo transferred) than patients aged nether 35 in 1991 (ix% per embryo transferred). Patients aged 43 and above have consistently had nascence rates below 5% per embryo transferred when using their ain eggs. In department 3 nosotros discuss how donor eggs can increase chances of success for older patients to higher up 20% on average.

two. Birth rates were above 20% per embryo transferred on average in the first 3 cycles
On average, about 1 in every iv embryos transferred resulted in a live nativity in 2018. Equally a event, many patients volition have more than one circular of embryo transfer; the average patient has three rounds.
The figure below shows the chances of a live birth by cycle number in 2018. The boilerplate age of a patient on their first cycle was 34.4 (green line) and their take chances of having a live birth on that wheel was 26% per embryo transferred (blue column). By contrast, the average age of a patient on their 10th bicycle was 38.9 and their chance of having a live birth on that cycle was 12% per embryo transferred.
The birth rate remains to a higher place 20% per embryo transferred for each of the commencement three cycles and steadily decreases with each new cycle. The reason the average birth rate is lower in later on cycles is related to the average patient age, as older patients have lower nascence rates and therefore require more cycles (see section 1).

three. Using donor eggs tin can result in loftier birth rates for older patients, but they are not widely used
Birth rates decrease with age where patients use their ain eggs in treatment. In 2018, nativity rates for patients below 35 were 31% per embryo transferred, compared to beneath 5% for patients 43 and above.
However, birth rates remained college (above 25%) for all ages when donor eggs were used as egg donors are five years younger on boilerplate (xxx.two) than IVF patients (35.vi).

Although it is clear from the effigy above that donor eggs can considerably increase the take chances of a alive nascence for patients twoscore years of historic period and older, only 18% of patients in this age group used donor eggs in 2018. In particular, while birth rates were comparably low for patients aged 43-44 (5%) and patients above 44 (4%) using their own eggs, patients above 44 years were 3 time more likely to employ donor eggs.
Of all patients undergoing IVF handling in 2018, 94.4% were in heterosexual relationships, 3.1% were in female same-sexual practice relationships, 2.0% had no partner and 0.5% acted every bit surrogates – with little change compared to 2017. While accounting for less than 5.5% of all IVF treatments, single patients, those in female same-sex relationships and surrogates accounted for 46% of all IVF cycles using donor gametes in patients under twoscore.

4. The multiple birth charge per unit decreased further to 8% in 2018
Multiple births are the biggest unmarried wellness take a chance from IVF to mothers and babies. In 2017, the 10% multiple birth rate target was accomplished for the first time nationally, but not across all age groups. In 2018, farther progress was made, as the 10% target was reached across all age groups and nationally only viii% of IVF births resulted in a multiple birth.

5. Transferring more than i embryo could result in a multiple birth rate over 30%
For each patient, the run a risk of a multiple birth is determined by the number of embryos put back and whether donor eggs were used. Our figures show that putting more than one embryo back has no meaning bear upon on the chance of a live birth just tin can considerably increment the risk of a multiple nascence.
Equally the effigy beneath shows, the risk of a multiple birth in IVF is comparable to natural formulation (two%), when only a single embryo is put back. Where two embryos were transferred, all the same, in that location was a 32% risk of a multiple birth for patients nether 35, without an increase in the chance of a live birth. In 2018, 21% of IVF cycles in patients under 35 had a double embryo transfer.
The conclusion to transfer more than 1 embryo at a fourth dimension should also consider the egg source. When two embryos were transferred, a 44-yr-quondam patient using donor eggs had about the same multiple birth risk as a 35-twelvemonth-one-time using their ain eggs. Of all cycles using donor eggs in patients 40 and over in 2018, 18% transferred back more than than one embryo.

half dozen. Embryo and egg storage have increased equally freezing becomes more common
The majority of patients using fertility services practice so with the intention of trying to excogitate equally soon as possible. However, at that place are other reasons people may use fertility services: to store their eggs and/or embryos for futurity use for fertility preservation; or to donate their eggs, sperm or embryos for use by another patient. While handling cycles increased by 12% betwixt 2013 and 2018, storage cycles increased much more than quickly, increasing by 523% from i,500 cycles in 2013 to just under 9,000 in 2018.
Equally freezing techniques have improved, a typical patient today will have a unmarried, fresh embryo transferred in their first cycle and whatsoever additional embryos created will be stored for use in subsequent frozen embryo transfers. Elective freeze-all cycles – where all fresh embryos are frozen after IVF to be used in later cycles – have as well get more than common. Equally a result, fresh embryo transfers decreased past eleven% between 2013 and 2018, while frozen embryo transfers almost doubled and accounted for 38% of all IVF cycles in 2018.

|---|---|---|---|
| Fresh embryo transfer | 48,391 | 42,835 | -xi% |

vii. NHS-funded cycles decreased in many English regions
In 2018 in Scotland, 60% of handling was NHS-funded, compared to 45% in Northern Ireland, 41% in Wales and 35% in England. In Scotland, Wales and Northern Ireland, the level of funding is set nationally. In England, funding is locally determined by Clinical Commissioning Groups (CCGs) leading to considerable regional variation in funding, as seen in the table below. In England, many CCGs take reduced funding for fertility treatment and as a result, the share of IVF cycles funded by the NHS has declined beyond nearly regions. The biggest decreases were seen in the E of England likewise as Yorkshire and the Humber, decreasing the England-broad share to 35% (41% in 2013).
Table 2. Funding trends are diverging nationally and regionally, with the overall number of NHS funded cycles declining
| UK nation | % of cycles funded by NHS | ||
|---|---|---|---|
| IVF cycles in 2018 | 2013 | 2018 | |
| England | 59,153 | 41% | 35% |
| London | 22,406 | 29% | 27% |

8. Fewer patients had their first IVF bicycle funded by the NHS
As discussed in section 7, many English language regions have seen a decrease in the proportion of treatments funded by the NHS. As a result, approximately 2,000 fewer patients had their first circular of treatment funded by the NHS in 2018 compared to 2017, while treatments in the private sector connected to grow. In 2018, 52% of get-go IVF cycles were funded by the NHS, compared to 58% in 2017.
