A September Campus meeting organised by the SIG Fertility Preservation reviewed approaches to fertility preservation in benign conditions such as endometriosis, POI and haematological diseases.

A September Campus meeting organised by the SIG Nursing and Midwifery reviewed current approaches to endometriosis management but heard that care must depend on a multidisciplinary approach in which nurses and midwives are an essential part.

A large cohort study from the Nordic countries has found that children born after FET had a higher risk of childhood cancer than children born after fresh embryo transfer and spontaneous conception, while no increased risk was found after any form of ART collectively. The authors urge caution in interpreting the results.

A series of editorials and studies in the August issue of Fertility & Sterility describe climate change as a major risk factor for reproductive health. Erratic weather and its consequences - air pollution, wildfires, heat stress, floods, and vector-borne diseases – will have an impact on male and female fertility.

Following a September Campus meeting organised by the SIG Fertility Preservation, Focus on Reproduction spoke to the SIG’s co-ordinator Professor Michaël Grynberg about indications, patient suitability and limitations to success in a range of conditions, including endometriosis, POI and pre-surgery.

A new meta-analysis finds that treatment with growth hormone in IVF is associated with improved reproductive outcomes largely mediated by an effect on endometrial function, especially in poor responders.

Although a substantial new meta-analysis has defined three morphokinetic variables significantly associated with aneuploidy, the review authors conclude that more evidence is needed before time-lapse and machine learning are ready for embryo assessment and selection of euploid embryos.

Two recently published papers have described experiments in which mouse embryo models were developed from pluripotent stem cells. Mina Popovic and Susana Chuva de Sousa Lopes from ESHRE’s SIG Stem Cells report.

A large Swedish registry study has failed to find any link between ART carried out in the summer months – when vitamin D levels may be highest – and improved birth rates. Once again seasonal variability appears to have no impact on IVF success.

At a time when the number of frozen embryo transfers is increasing worldwide, a new RCT in unmedicated cycle FETs found a statistically higher birth rate when supplemented in the luteal phase with vaginal progesterone; such support, write the authors, ‘should be considered for introduction in clinical routine’.
