Unplanned pregnancies following the introduction of elexacaftor/tezacaftor/ivacaftor therapy in women with cystic fibrosis.
    Archives of gynecology and obstetrics, 2023, Volume: 308, Issue:5

    Cystic fibrosis (CF) causes infertility and subfertility due to various factors, including altered cervical mucus, delayed puberty, and hormonal imbalances. With the introduction of the CFTR modulator therapy elexacaftor-tezacaftor-ivacaftor, we have observed an increase in unplanned pregnancies among women undergoing ETI treatment in our CF center, despite repeated recommendations for strict fertility monitoring. It appears that these pregnancies are more likely attributed to reduced attention to the possibility of conception rather than contraceptive failure. The perception of subfertility developed by women with CF over time, before the era of modulators, can influence their long-term habits and lead to the underuse of contraceptive methods. While further research is needed to fully understand the effects of ETI on fertility, healthcare providers should be attentive to the fertility concerns of women with CF, particularly those treated with modulators in adulthood.

Elexacafator/tezacaftor/ivacaftor resolves subfertility in females with CF: A two center case series.
    Journal of cystic fibrosis : official journal of the European Cystic Fibrosis Society, 2021, Volume: 20, Issue:3

    Infertility and subfertility are commonly faced by females with cystic fibrosis (FwCF) and resulting in decreased contraceptive use and increased utilization of reproductive technologies. Elexacaftor-tezacaftor-ivacaftor (ETI) is a CFTR modulator that affects common causes of subfertility. Two CF centers conducted a retrospective chart review on females with CF who were receiving ETI and became pregnant. We analyzed obstetrical-gynecological history, genotype, and clinical response to ETI therapy. Fourteen FwCF on ETI became pregnant. Half (7) of the FwCFs were previously attempting to conceive, but only three were using contraceptives. Four FwCF had a history of infertility; two were reconsidering use of reproductive technologies (IUI). Patients achieved conception at mean 8 weeks after initiating ETI. ETI may lessen CF-associated factors that affect fertility; however, its exact mechanism is unknown. This warrants counseling on contraceptive use and family planning prior to initiation of therapy and at routine intervals while utilizing ETI.
