How UK IVF Birth Rates Rose From 2014 Through 2016

This is a national registry report. The UK's fertility regulator, the HFEA, tracks every licensed IVF cycle in the UK. The report covers 2014 to 2016, among more than 68,000 cycles in 2016 alone. IVF birth rates rose for 25 years while multiple births kept falling.

Key Findings

  • UK clinics carried out just over 68,000 IVF cycles in 2016, a 4% increase on 2015, and 20,028 of those cycles ended in a birth.
  • Fresh cycles reached a 21% birth rate per embryo transferred in 2016, and frozen cycles reached 22%; both sat near 8% and 6% in 1991.
  • Birth rates per embryo transferred fell with age: 29% for fresh cycles under 35, versus 7% for fresh cycles at ages 43 to 44.
  • The multiple birth rate for IVF fell from 28% in 1991 to 11% in 2016, with no drop in the overall birth rate.
  • Most IVF cycles (88%) used a patient's own eggs and partner's sperm; 12% used donor eggs, donor sperm, or both.

Interpretation

This report comes from the HFEA, the UK's fertility regulator. The report counts every licensed IVF cycle in the UK from 2014 to 2016, with trends back to 1991. The figures are a whole-population count. They are not from a trial with matched groups. So it cannot explain why birth rates rose or multiple births fell, only that both happened together. Results are broken down by age, funding, and egg or sperm source, but not by clinic or diagnosis. The report tracks births two ways: for each embryo placed back, or for each cycle begun. A national average like this cannot predict what will happen for one couple.

RRM Context

This report counts how many IVF cycles led to a birth. The report does not look at why each couple could not conceive, beyond broad labels like an ovulatory problem, blocked tubes, or endometriosis. RRM instead evaluates both partners to find the specific cause. The cause-finding question differs from how many cycles a national registry recorded.
