Comparable outcomes from fresh and vitrified sibling oocytes found in large egg donation series

The largest study to compare the viability of vitrified and fresh sibling oocytes has reaffirmed their comparable efficacy, but only when the efficiency of the vitrification procedure – and oocyte loss at warming - are taken into account.



‘No safe level’ of caffeine consumption for pregnant women and would-be mothers

A review of findings from observational studies and meta-analyses concludes that maternal caffeine consumption is ‘reliably’ associated with several adverse outcomes of pregnancy. Pregnant women advised ‘to avoid caffeine’.



Mitochondrial DNA in sperm linked to fertility and pregnancy probability

A cohort study in non-IVF couples trying to get pregnant has found that sperm mitochondrial DNA copy number may be useful as a biomarker of male reproductive health and the likelihood of pregnancy, even in the general population.



A time like no other: ESHRE in the first six months of COVID-19

It was in mid-March this year, in the face of an alarming rise in coronavirus infections and restrictions on travel, that ESHRE cancelled its upcoming Campus meetings. Two weeks later the annual meeting was also cancelled and a week after that, on 2 April, ESHRE’s precautionary statement on fertility services advised that all but essential treatments ‘should not be started’. For ESHRE and the entire fertility sector these were steps never taken before. How did ESHRE cope over the next six months? Could an organisation even as successful as ESHRE continue with its everyday business?
