Use of CFTR modulators in pregnancy: new information for neonatal, paediatrics and midwifery teams.

Cystic fibrosis (CF) is common, multisystem, life-limiting genetic condition, predominantly in the Caucasian population. There have been recent advances in the management of CF, in particular in the last 5 years following approval of cystic fibrosis transmembrane conductance regulator (CFTR) protein modulators by the National Health Service (NHS) for use in people with CF (pwCF).Traditionally, almost 40% of female patients with CF (fwCF) and over 95% of male patients with CF (mwCF) have issues with subfertility or infertility.
