BACKGROUND With increasing life expectancy, issues of fertility and pregnancy are pertinent to patients with cystic fibrosis. For this reason, the four Scottish Cystic Fibrosis centres asked men and women with cystic fibrosis about their attitudes to fertility and to information given to them by health professionals.
METHODS A postal questionnaire was sent to 116 men and 79 women aged 16 years and over attending four Scottish Cystic Fibrosis clinics.
RESULTS There was a 70% response rate (82 men, 54 women). All but two men knew that they were likely to be infertile. 37% of respondents lived with a partner; 14 women (26%) and five men (6%) had children. For 85% of men and 72% of women having children was important now or would be in the next 10 years. 43% of men and 26% of women had never had any discussion on fertility issues with cystic fibrosis health professionals. 56% of men thought that first discussion with a health professional about infertility should be before the age of 16 years; 12% remembered having a first discussion at that age. Learning of their infertility was associated with strong negative emotions for most men. Women were more likely than men to have initiated first discussion (17 (32%) versus eight (10%); p<0.01). Twenty five men (31%) and 32 women (59%) were currently using contraception. Ten men (12%) and 15 women (28%) had discussed contraception at the Cystic Fibrosis clinic (p = 0.01).
CONCLUSIONS Parenting and fertility issues are important for men and women with cystic fibrosis but many patients do not find out what they want to know from discussion with health professionals. Patients want discussion to begin in early adolescence. Men in particular are likely to be reluctant to introduce these issues; health professionals should be aware of the need actively to initiate discussion.

It is estimated that there are 2700 people aged over 16 with cystic fibrosis in the UK.1 Children born with cystic fibrosis in 1990 are estimated to have a life expectancy of 40 years, double that of 20 years ago.2 This increase in the population of adults with cystic fibrosis means that they will need information on sexuality and fertility.
Fertility is a particularly sensitive and important issue in cystic fibrosis because more than 95% of male sufferers are infertile.3 Although infertile, sexual function is not usually affected by cystic fibrosis.4 Women with cystic fibrosis may have reduced fertility5 ,6 and pregnancy may put their health at risk.6 Because of this, pregnancy in women with cystic fibrosis should be planned and discussed with the relevant team.3
Studies suggest that not all subjects with cystic fibrosis understand how this affects their reproductive capacity. In a previous study in the UK only 27% of men and women with cystic fibrosis knew how the reproductive organs are affected.7 In another study Conwayet al 8 found that 10 out of 37 men thought that men with cystic fibrosis were not infertile. In contrast, an Australian study by Sawyer et al 9 found that 90% of men over 17 years knew they were infertile.
An unpublished study by Thicket et al in 72 men with cystic fibrosis attending the Birmingham Adult Cystic Fibrosis Unit found that 88% were sexually active but 56% had never received advice on contraception and infertility. Fifty seven percent were aware that it is rare for men with cystic fibrosis to father children, but 68% expressed a wish to have children. Shepherd et al 10 found that men and women with cystic fibrosis were as likely to be married or in a sexual relationship as a non-cystic fibrosis matched control group.
Sawyer et al 9 found that 83% of 14–17 year old boys said that being infertile was not significant while only 10% of men over 17 regarded their infertility as insignificant. They suggest that the significance of infertility changes with age, and that the issue should be introduced at around the age of 14 years and returned to in later reviews. Hameset al 7 found that patients under 13 wanted to receive information from both their parents and clinical staff, while those aged over 13 preferred that health care providers supplied them with information. Johannessonet al 11 found that adult Danish women with cystic fibrosis thought that 13–14 years was the best time to introduce discussion about sexuality. Few women felt they had had satisfactory discussions. It was concluded that feelings such as denial, anger, and grief about fertility decisions were present among the women interviewed. Glover et al 12 found that men not suffering from cystic fibrosis who attended a specialist male subfertility clinic felt “less of a man”, had high levels of anxiety, and blamed themselves for their infertility. Sawyer et alfound similar negative feelings among men with cystic fibrosis.9
The four Scottish adult Cystic Fibrosis clinics (based in Aberdeen, Dundee, Edinburgh and Glasgow) felt it would be of value to carry out a study investigating fertility issues. The aims of the study were (1) to determine attitudes about fertility and pregnancy among subjects with cystic fibrosis aged 16 years and over attending the clinics and (2) to determine satisfaction with communication on this issue from health professionals.
The study population comprised 116 men and 79 women from the four Scottish Cystic Fibrosis clinics aged 16 years and over. In Scotland transfer to an adult Cystic Fibrosis clinic usually takes place at the age of 14. Twenty men and three women were excluded from the study at the discretion of their consultant.
A questionnaire was developed by nurses from all the centres, psychologists (two centres), consultants (all centres), and representatives of the National Services Division, NHS. It was piloted on eight adult patients from the centres, four men and four women. From the results of the pilot study an amended questionnaire was finalised. Approval for the study was obtained from the ethics committee of each participating centre.
The male questionnaire dealt with discussion about infertility while the female questionnaire focused on the issue of pregnancy for women with cystic fibrosis. Some questions were identical for men and women such as “Do you live with a partner?”, “How do you feel if a health professional questions whether or not you should have a child?”, “Has (male infertility)/(fertility or pregnancy) in cystic fibrosis ever been discussed with you by a health professional?”, “Have you been able to find out all you want to know during these discussions?”. Questions in the male questionnaire that had no equivalent in the female questionnaire asked if the respondent was aware that men with cystic fibrosis were usually infertile, at what age they had learnt this, from whom, and what they had felt about their probable infertility.
For all patients surveyed, participating centres provided the most recent percentage predicted forced expiratory volume in one second (FEV1) for age, sex and height, and body mass index (BMI).
ANALYSIS OF DATA
SPSS-PC was used to store and analyse quantitative data. Two tailed Student's t tests were used to test for significant differences between subgroups for parametric data and Mann-Whitney U tests and χ2 tests were used for non-parametric data. The NUD*ist package was used to classify open ended, qualitative responses.
Twenty three patients were excluded from the study, mainly for social reasons—for example, being in prison or a request by the mother of a patient that he be excluded. It was thought possible that three of the excluded men did not know of male infertility. Excluded patients did not differ in mean age (24 years versus 26 years, p = 0.13), but they had better mean FEV1 (63% versus 55% predicted, p<0.05).
Of the 195 patients sent a questionnaire 136 (70%) responded (82 men and 54 women). There were no differences between respondents and non-respondents in sex, mean age (25 years versus 26 years), or mean FEV1 (56% versus 51% predicted, p = 0.10).
The characteristics of the 136 patients who participated in the study are shown in table 1. Their median age was 24 years and most had been diagnosed in early childhood. Median FEV1 was 53% for men and 60% predicted for women. Thirty nine men (48%) and 26 women (48%) were in employment.
LEARNING OF INFERTILITY: MEN
All but two men said they were aware that men with cystic fibrosis are usually infertile. Neither of these men lived with a partner or had children. Twenty nine men (37%) learnt that they were infertile before the age of 16 and 20% between 16 and 19. Twenty one (26%) were over 20 years and 15 did not answer the question or could not remember. Thirty four men (41%) had found out about their infertility from the Cystic Fibrosis clinic, 21 (26%) from their parents, and 16 (20%) from Cystic Fibrosis Trust leaflets. Learning from parents was usually before 16 years (67%, p<0.01), learning from the clinic was after 20 years (62%, p<0.01), and learning from literature was most common between 16 and 19 years (50%, p<0.01).
When men were asked how they felt when told of their infertility, the most common replies were “shocked” (33, 40%), “bewildered” (19, 24%) and “angry” (15, 19%). Nineteen men (24%) reported feeling “not bothered”. Only one reported feeling “relieved or pleased” (table 2).
MEN'S EXPERIENCE OF ASSISTED FERTILITY PROGRAMMES
Thirty men said they had some knowledge of assisted fertility programmes. Four had successfully had a child through assisted fertility and two had been unsuccessful in a programme.
HAVING A FAMILY: MEN AND WOMEN
Thirty men (37%) and 20 women (37%) were married or living with a partner. Fourteen women (26%) had children and five men (6%) described themselves as having children (four through an assisted fertility programme) (table 1). Men and women who were married or living with a partner were older (mean age 31 versus 23 years, p<0.001) but had similar mean FEV1 (57% versus 55% predicted, NS) to those not living with a partner. Men and women with children were older than those without (33 versus 25 years, p<0.001) and had higher FEV1 (68.1% versus 53.7% predicted, p<0.01).
Most respondents described having children as being important either now or in the future (table 2). More than half worried that, if they had a child, it would have cystic fibrosis. One in three respondents would be angry if a health professional questioned whether they should have a child (table 2; box FB1). Among those who did not have children at present, respondents who thought having children now or in the next 10 years was important did not differ in lung function from those who did not think having children was important (mean FEV1 (53% versus 58% predicted, NS).
CONTRACEPTION: MEN AND WOMEN
Twenty five men (31%) and 32 women (59%) were using some form of contraception (condom for men; pill or IUD for women). Ten men (12%) and 15 women (28%) (p<0.05) had discussed contraception at a Cystic Fibrosis clinic (table 3).
DISCUSSION WITH A HEALTH PROFESSIONAL: MEN AND WOMEN
Women were more likely than men to have discussed fertility with a health professional (74% versus 57%, p<0.05; table 3). Women were more likely than men to start the first discussion (32% versus 10%, p<0.01). Twelve men (15%) and 12 women (24%) said they had been able to find out all they wanted to know from discussions with a health professional. Fifty eight per cent of men and women wanted written information about fertility issues, pregnancy, or screening. Less than a quarter (18 men (24%) and seven women (14%)) remembered receiving any.
AGE AND PERSON FOR FIRST DISCUSSION: MEN AND WOMEN
Table 3 shows that, although few men had their first discussion with a health professional about infertility before the age of 16, this was men's preferred age for first discussion (46, 57%). Women suggested 16–19 years (25, 46%). Eighteen women (34%) had had a first discussion at this age. Only nine men (11%) and nine women (17%) thought first discussion should be at over 20 years. Most men (69, 84%) and women (37, 69%) said they had no preference for discussion with someone of the same sex, but when asked which health professional they would prefer, men preferred to discuss with a doctor (46, 56%) and women preferred a cystic fibrosis nurse (38, 70%).
OPEN ENDED COMMENTS
Thirty men (37%) and 38 women (70%) gave comments to open ended questions. The 24 men aged 20 years or less were particularly unlikely to answer open ended questions (6, 25%).
TALKING TO HEALTH PROFESSIONALS
In an open ended question men and women were asked to comment on talking to health professionals about fertility and to comment on how they would feel if a health professional questioned if they should have a child. Some examples of comments are shown in box FB1.
WHAT SORT OF INFORMATION?
Box FB2 shows examples of comments on the kind of information wanted. Women gave a detailed and rich commentary on the information they thought should be given. Three themes emerged from female responses: (1) wanting more information about health consequences of pregnancy, (2) suggesting information to give to other women, particularly about the long term health effects from pregnancy; and (3) describing satisfactory and unsatisfactory discussion with cystic fibrosis doctors and nurses.
Men made few specific suggestions about what information they wanted and seemed to divide into those who wanted “the facts” and those who wanted the emotional impact of infertility to be recognised by their health professionals. Most men did not seem to be aware of the relatively low success rate of assisted fertility treatment. Of 30 comments from men, nine were on the positive chance that they would be able to have children through assisted fertility and no man commented on the low success rate of fertility programmes. As noted previously, men aged 20 years and under were much less likely than women or older men to make any comment on what information they wanted. Older men with good lung function seemed most likely to be distressed by their infertility (box FB2).
These results show that having children is important to most men and women with cystic fibrosis, but only a few men and women felt they had been able to have an adequate discussion with a health professional about fertility.
Among the respondents, all but two men knew they were probably infertile (another three excluded men may not have known). This is similar to the study by Sawyer et al 9 in which 90% of adult men knew they were infertile. Patients who learnt through the Cystic Fibrosis clinic were older than patients who learnt from their parents. This suggests that the topic has commonly not been dealt with by health professionals during adolescence.
Although women seem more able to introduce discussion of fertility issues than men, women often did not feel that they were given adequate information. Contraception, reproductive health, and timing of pregnancy are all issues on which women with cystic fibrosis need advice in order to be able to make informed decisions. In the present study 22% of women had been able to find out what they wanted to know from discussions with health professionals; 59% were using contraception (compared to national UK rates of 65%13) and half of these had discussed contraception at their Cystic Fibrosis clinic. Few men (12%) reported any discussion of contraception in the clinic in spite of its importance for avoiding risk of sexually transmitted disease and thrush.
It is possible that these results do have some distortion from incorrect recall and they reflect practice over the person's 20 years of care. However, the preferences of our respondents were clear. The patients' judgement, looking back on their experience, was that fertility issues should be introduced by health professionals during adolescence. Sawyer et al 14found among 40 men aged 18–53 years that the median age at which patients thought it appropriate to learn about infertility was 14 years; the median age at which the respondents had learnt was 16 years. Similarly, in our study 56% of men think that 12–15 is the best age to discuss infertility but only 12% remembered having a discussion at that age. However, men did not give us a clear picture of what information they thought should be given at this age. Infertility obviously aroused strong negative feelings in many of our respondents; 20% of the respondents in the study by Sawyer et al 14 confused infertility with impotence. Puberty is delayed in many young men with cystic fibrosis and Sinnemaet al 15 found that intimacy and sexual relationships were delayed among boys and girls with cystic fibrosis in comparison with a non-cystic fibrosis control group. Men with cystic fibrosis are likely to have small volume ejaculates.15 It is possible that the issue of “being normal” is what boys want addressed at early puberty.
Men said that they would prefer to discuss infertility with a doctor but women preferred to discuss pregnancy with a cystic fibrosis nurse. It was not clear why this was so. Although most denied this when explicitly questioned, people with cystic fibrosis may prefer to discuss these issues with their own sex and their expectation may be that most doctors are men and nurses are women.
EMOTIONS AND ADVICE ON FERTILITY
Sawyer et al 14 believed that there was little evidence of negative emotion associated with learning of infertility, but two thirds of men in this survey reported feeling negative emotions such as shock and bewilderment when told that they were infertile. Between 30% and 40% of men and women said they would feel angry if a health professional questioned whether they should have a child. Genetic screening advice is a sensitive area even when it is not associated with personal health concerns. Sawyer6 found that many women overestimated the risk of having a child with cystic fibrosis. Almost two thirds of men and women in the present study were worried that, if they had a child, it too would have cystic fibrosis. Previous studies have shown the adverse psychological effect of knowledge about carrier status.17Health professionals may underestimate the emotional impact of genetic information.
In conclusion, this study and previous studies6 ,18indicate that discussion should start in early adolescence. The content of discussion will change as patients mature, particularly for men. A 14 year old boy probably needs the basic facts of his infertility, with reassurance that his development will be normal and that infertility does not affect sexuality. A 25 year old might want detailed information about infertility treatments. Women of all ages want advice on reproductive health, and the health implications and possibilities for pregnancy. Men and women will be concerned about genetic issues when they begin long term relationships and consider decisions about parenting. In this survey patients in their late twenties were likely to be living with a partner and to place importance on having children.
Having better or worse lung function was not significantly related to the likelihood of living with a partner, using contraception, or placing importance on having children, although the open ended comments suggested that older men with good lung function found it more difficult to come to terms with infertility.
It is the responsibility of Cystic Fibrosis centres to offer information on fertility to patients with during adolescence and, in the case of women, to discuss with individual patients the potential impact of pregnancy on cystic fibrosis. Patients can then make informed choices. The onus is on health professionals to instigate discussion about fertility because it appears that people find it a difficult subject to bring up themselves.
