GLP-1 exposure around conception: no signal in pooled pregnancy outcomes, and a reminder on contraception
A meta-analysis of 186,598 pregnancies finds no change in the odds of preterm birth or pre-eclampsia after early GLP-1 exposure, a review urges contraceptive counselling at GLP-1 initiation, and doula support, uterus transplantation and brief skin-to-skin contact at caesarean add to the week's evidence.
The edition in brief
A systematic review and meta-analysis of eight observational and trial datasets (186,598 pregnancies, 47,159 exposed) found no statistically significant change in the odds of gestational diabetes, preterm birth, pre-eclampsia or hypertensive disorders after GLP-1 receptor agonist exposure around conception. Heterogeneity was high and study quality varied, so the result is reassuring rather than definitive. An AJOG narrative review notes that evidence on interactions between GLP-1 receptor agonists and hormonal contraception is limited and recommends contraceptive counselling whenever one is started. A GRADE-rated review of 30 studies of doula support in the United States found moderate-certainty associations with lower preterm birth and caesarean rates, though most studies were at high risk of bias. A prospective US cohort of 60 uterus transplants reported 70% achieving a live birth or ongoing pregnancy, with reoperation in 28.3% of recipients and 58.3% preterm birth among 48 neonates. A small randomised trial of 60 term newborns found lower pain scores during the first injection after brief skin-to-skin contact during caesarean delivery.
GLP-1 receptor agonists around conception: no pooled signal for maternal complications
If a patient conceives on a GLP-1 receptor agonist, these pooled data give no reason to expect more maternal complications, but review the plan for the drug and glucose monitoring rather than relying on this alone.
Doula support: moderate-certainty links to fewer preterm births and caesareans
Consider supporting continuous labour companionship where it can be offered, while telling patients the benefits are associations drawn largely from weaker studies.
Ten years of uterus transplantation in the United States: births, but frequent reoperation
When counselling about uterus transplantation, give the reoperation, donor risk and preterm birth figures alongside the live birth rate.
Brief skin-to-skin contact at caesarean and newborn pain during the first injection
Where theatre conditions allow, brief skin-to-skin contact at caesarean is worth offering; do not treat it as a replacement for other pain-reduction measures for neonatal injections.
Ask about weight-loss and diabetes injections at every preconception visit
Add a direct question about injectable weight-loss and diabetes drugs to the preconception checklist.
Make contraceptive counselling part of starting a GLP-1 receptor agonist
When a woman of reproductive age starts a GLP-1 receptor agonist, discuss contraception at the same visit and consider whether her current method suits her.
