The Scientific and Clinical Advances Advisory Committee (SCAAC) met on 3 February 2025. Papers from the meeting are available on the SCAAC webpage.
The Committee discussed developments in the following horizon scanning topics and allocated a rating to androgen supplementation as a treatment add-on:
Health outcomes in children conceived by Assisted Reproductive Technology (ART)
A paper summarising research developments in health outcomes in children born from ART (including the impact of culture media) was presented to the Committee for discussion. Members discussed the challenges of studying the impact of culture media, the limitations of linkage studies, and use of HFEA Register data. It was agreed that health outcomes for ART patients (including gestational surrogates and egg donors) should become a separate SCAAC horizon scanning topic.
Impact of stress on fertility treatment outcomes
Members considered research developments on stress and its associations with fertility treatment outcomes, including stress as a factor in the decision to discontinue fertility treatment. It was agreed that, while treatment may be stressful for patients, measurements of stress are heterogeneous making the relationship between stress and treatment outcomes difficult to determine. Outcomes aside, patients should be encouraged to seek interventions that reduce stress due to the likely positive impact on their stress levels and emotional wellbeing.
Mitochondrial donation: polar body transfer
Mitochondrial donation was brought back to the Committee to discuss research on the technique of polar body transfer, published since the last review in November 2016. Polar body transfer is currently unlawful in treatment in the UK. Members agreed that, despite the promise of lowering the risk of carryover of affected mitochondria, research is still experimental and not yet sufficient to make a strong case for further review or legislative change.
Androgen supplementation as a treatment add-on
During the June 2024 SCAAC meeting, the Committee advised that androgen supplementation met the criteria to be eligible for an HFEA treatment add-on rating. The Committee subsequently rated both dehydroepiandrosterone (DHEA) and testosterone for use by most fertility patients, older women, and women with poor/diminished ovarian reserve. Further information will be added to the ‘Treatment add-ons with limited evidence’ webpage in due course.
In addition, the SCAAC reviewed the prioritisation of their horizon scanning topics and agreed their workplan for 2025/26. Research developments in the topics of ‘Reproductive organoids’ and ‘Health outcomes for ART patients (including gestational surrogates and egg donors)’ will now be considered through the SCAAC’s horizon scanning function.
Once approved, minutes from the meeting will be available on the SCAAC webpage.
