Current status of fertility and family formation in men with cystic fibrosis

A provider survey assessing fetal impact of CFTR modulator use in males with CF during assisted and unassisted reproduction and partner pregnancy

BACKGROUND

Most males with cystic fibrosis (mwCF) are infertile but with CF transmembrane conductance regulator (CFTR) modulator-conferred benefits, more are utilizing assisted reproductive technologies (ART). Administration of normal human doses of modulators in animal reproductive models caused no genotoxicity; no human data exists. Potential health decline following modulator discontinuation makes the decision to withhold therapy during reproduction challenging.

METHODS

From August-October 2021, international CF clinicians completed an anonymous questionnaire regarding mwCF who used modulators during reproduction.

RESULTS

We received 42 surveys for mwCF with partner pregnancies. Forty of 42 mwCF utilized ART; 35 continued modulators during sperm retrieval and 40/42 during partner pregnancy. One of four males who discontinued modulators experienced clinical deterioration. First trimester miscarriages occurred in 11.9 % of partner pregnancies. No congenital anomalies were reported.

CONCLUSIONS

Use of CFTR modulators during reproduction and partner pregnancy in mwCF did not result in a higher-than-expected miscarriage rate nor congenital anomalies.

Reproductive Counseling and Care in Cystic Fibrosis: A Multidisciplinary Approach for a New Therapeutic Era

With the advent of highly effective modulator therapies, many people with cystic fibrosis (CF) are living longer, healthier lives. Pregnancy rates for women with CF more than doubled between 2019 and 2021, reflecting increases in both planned and unplanned pregnancies. For men with CF, CF-associated infertility can be mitigated with assistive reproductive technology, yet patient knowledge of these challenges and options is variable. Preconception and prenatal counseling for individuals with CF and for parents of children with CF who wish to expand their families requires nuanced discussions to promote informed reproductive decisions, drawing from a combination of standard practice recommendations and CF-specific assessments. This review article synthesizes the current literature and practice recommendations regarding reproductive counseling and care in CF, outlining the role of genetic counseling, carrier screening, teratogen counseling, in vitro fertilization and pre-implantation genetic diagnosis, and careful assessment and management of cystic fibrosis-related diabetes when present. Via a multidisciplinary, patient-centered approach, clinicians can support adults with CF and parents of children with CF as they make informed reproductive decisions and embark on family planning.

"Find ways to work parenting into cystic fibrosis": A PhotoVoice exploration of being a parent and having CF

BACKGROUND

As more people with cystic fibrosis (CF) consider their reproductive futures, the impact of parenthood on CF must be better understood. In the context of chronic disease, deciding if, when, and how to become a parent is complex. Little research has investigated how parents with CF balance their role as parents with its associated health impacts and demands of CF.

METHODS

PhotoVoice is a research methodology that utilizes photography to generate discussion about community issues. We recruited parents with CF with at least 1 child <10 years old and divided them into three cohorts. Each cohort met five times. Cohorts developed photography prompts, took photographs between sessions, and reflected on the photos at subsequent meetings. At the final meeting, participants selected 2-3 pictures, wrote captions, and as a group organized the photographs into thematic groups. Secondary thematic analysis identified metathemes.

RESULTS

Participants (n = 18) generated a total of 202 photographs. Each cohort identified 3-4 themes (n = 10) which secondary analysis grouped into 3 metathemes: (1) It is important for parents with CF to pay attention to the joyful aspects of parenting and to cultivate positive experiences; (2) Parenting with CF requires balancing your own needs with those of your child, and creativity and flexibility can be key; (3) Parenting with CF consists of competing priorities and expectations often with no clear "correct" choice.

CONCLUSIONS

Parents with CF identified unique challenges to their existence as both parents and patients as well as ways in which parenting has enhanced their lives.
