Female subfertility (W15) has an incidence of 3.8 per 1000 patient years, meaning almost four new diagnoses of female subfertility in a year in a practice with 1000 female patients. Link/Figure 1
Male subfertility (Y10) has an incidence of 2.8 per 1000 patient years, meaning almost three new diagnoses of male subfertility in a year in a practice with 1000 male patients. Link/Figure 2
The prevalence of ‘subfertility female’ (W15) is 8.1 per 1000 female patient years, meaning that among 1000 female patients in a year, eight receive help or guidance from their GP for subfertility. Link/Figure 3
The prevalence of ‘subfertility male’ (Y10) is 3.9 per 1000 male patient years, meaning that among 1000 male patients in a year, four receive help or guidance from their GP for subfertility. Link/Figure 4
Subfertility is usually a problem for a couple, but is recorded more commonly among female patients in the FaMe-Net database than among males. In this website, data cannot be studied in residential association (i.e. for couples). This would be possible with additional data extractions (on request). The data implies, however, that subfertility as a health problem is sometimes presented to the GP by a couple but sometimes by a woman alone.
The incidence and prevalence are highest in the age group 25-44 years, both among women and men. In this age group, 26 per 1000 female patients present to their GP with subfertility throughout the year (prevalence). Subfertility is also prevalent in the age group 15-24 years, especially among women (1.3 per 1000 patient years). In the age group 45-64 years, a new or existing diagnosis of subfertility is rare, but occurs more often in men (incidence 0.6, prevalence 0.9 per 1000 patient years) compared to women (incidence 0.3, prevalence 0.6 per 1000 patient years).
Among women aged 25-44, subfertility is ranked 34 in the ‘Top Prevalence’ list of conditions affecting a large proportion of the population and presented to the GP. ‘Pregnancy’ (W78) is the number one prevalent condition in this group, followed by two other reproduction related conditions (oral contraception (W11) and intrauterine contraception (W12)).
