Reproductive Health and Fertility Challenges in Cystinosis

As patients with cystinosis are living longer into adulthood, they may wish to have children but often face reproductive complications. With appropriate planning and care, some patients may have successful reproductive outcomes.1-4

Delayed puberty, growth failure, hypothyroidism, and renal impairment can negatively impact reproductive health and fertility in patients with cystinosis.5-7

Most adult males with cystinosis are considered infertile. This is primarily due to hypogonadism, testicular dysfunction, and obstructive azoospermia.2,9 Fertility assessments, including semen analysis, can provide insights into the reproductive potential of males with cystinosis. If reproduction is desired, fertility preservation using sperm cryopreservation with or without surgical testicular or epididymal sperm extraction can be pursued and used for assisted reproductive techniques, such as in vitro fertilization.2,10

Females with cystinosis are typically fertile, though delayed menarche may occur. While females with cystinosis may be able to conceive naturally, there are significant risks associated with pregnancy.2,4

It is important for patients and caregivers to have open discussions with health care providers regarding reproductive health concerns in cystinosis, and these conversations should be initiated early in adolescence and continue into adulthood.8,10 Fertility specialists, endocrinologists, urologists, obstetrician-gynecologists, maternal-fetal medicine specialists, and genetic counselors can provide guidance and support in addressing family planning concerns and navigating reproductive issues associated with cystinosis.10,11
