For how we live.
A European trial stopped early for futility: clinical pregnancy occurred in 15.7% of women given transdermal testosterone before IVF and 14.9% given placebo. The trial was funded by Ferring.
In a 4,376-woman trial across 24 Chinese centres, natural-cycle embryo transfer gave the same healthy-live-birth rate as a programmed hormone regimen, with less pre-eclampsia and postpartum haemorrhage.
Popular extras like embryo genetic testing and endometrial scratching did not raise live-birth rates in their biggest randomised trials, and the UK regulator warns most patients need none of them.
In two large clinics, the live birth rate per woman who returned to use her eggs was around 39-50% under 35 or 38, but far lower for older women — and most women who froze never came back to use them.
An 876-participant double-blind trial across 24 Chinese fertility centres nearly doubled serum 25-OHD in women with PCOS. Live births were 52.0% against 50.2% on placebo.
