Infertility in Males
Although men with Cystic Fibrosis still may
have a great sex life, the majority of them
are infertile.

are characterized by congenital bilateral
absence of vas deferens (CBAVD).
Congenital bilateral absence of the vas deferens
 The improper development of the tube through
which sperm are released from the testes.
 Similar to being born with a vasectomy; you

 Causes of CBVAD are genetic mutations and
variations in the CF gene.
Female Infertility
Females with CF are less fertile than
normal healthy women.
 Delayed puberty and amenorrhoea are
common due to malnutrition.
 Women with CF have a thicker cervical
mucus which makes it hard for the sperm
to swim through, however not impossible.
