Nineteen PCCs have been scheduled for this year’s annual meeting, 13 organised by ESHRE’s Special Interest Groups covering a wide range of themes and presenting speakers of international renown. A record number of abstracts have been received for the main scientific programme.

A well attended Campus meeting in December organised jointly by the ESHRE SIGs Implantation & Early Pregnancy and Endometriosis & Endometrial Disorders considered the conditions and diseases associated with recurring loss of pregnancy, and the interplay between endometrial and embryonic factors.

A survey of how centres manage chromosomal mosaicism in their PGT patients was the basis for new ESHRE recommendations. There remain many knowns and unknowns, but the new publication offers recommendations on how to manage the detection of chromosomal mosaicism, validation of techniques, risk assessment, reporting, embryo transfer policies, prenatal testing and genetic counselling.

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.

Although most cases of endometrial cancer are diagnosed in postmenopausal women, there is a minority for whom pregnancy remains welcome and possible. This February Campus meeting explored the treatment of endometrial cancer with fertility preservation in mind, with many speakers members of the new guideline’s development group.

A Campus meeting in November organised by four ESHRE SIGs reviewed the most common source of errors in fertility clinics – in egg collection, embryo transfer and OHSS – but maintained throughout that scrupulous reporting and being honest with patients were necessary to maintain and restore trust.

A follow-up to the 2017 meta-analysis of Levine et al finds that sperm count is declining at an accelerated pace (now at 2.64% per year) and throughout all parts of world; male fertility described as a ‘major public health problem’.

ESHRE hosted a session at the annual conference of the UK’s Progress Educational Trust, the publishers of BioNews. The conference’s overall theme was fair access to treatment, with the ESHRE session looking at disparities in funding and regulation in four European countries: Turkey, Belgium, Germany and Italy.

A large cohort study from Canada has found that around 2% of pregnant women used cannabis during the study period and that this use was particularly associated with a greater infant risk of preterm birth, low birth weight and small-for-gestational age.

A far-reaching Campus meeting in support of the Male Reproductive Health Initiative exposed gaps in the diagnosis and treatment of male infertility and highlighted basic needs for research. Men’s reproductive medicine, said the WHO, is ‘important but neglected’.
