Most male cystic fibrosis (CF) patients are infertile due to obstructive az
ospermia but little is known about the best time to counsel patients on inf
ertility. All male patients attending the Adult Nottingham CF unit were inv
ited to complete an anonymous questionnaire on infertility. The response ra
te was 60%. The median age that the patients first became aware of male inf
ertility was 17 years (range 13-24) but the preferred age of receiving this
information was 14 years (range 8-16). Patients first learnt about male in
fertility from the CF team (six patients), parents (five), from written inf
ormation (two) or unexpectedly (five). Five out of 18 patients had undergon
e seminal analysis at a median age of 26 years but 17/18 patients felt that
this should be offered routinely. Our survey has shown that patients would
like infertility discussions at a younger age and routine seminal analysis
.
