ABSTRACT
BACKGROUND: Reduced female fertility in CF is believed to be due to thick cervical mucous, poor nutritional status, functional hypogonadotropic hypogonadism and possibly increased inflammation. Literature suggests that reduced ovarian reserve may also play a role. METHODS: 20 women with CF and 20 controls age 18-35 years were recruited. Serum anti-mullerian hormone (AMH), estradiol and follicle stimulating hormone (FSH) were assessed as well as antral follicle count (AFC) using transvaginal ultrasound. RESULTS: Women with CF had significantly lower AMH levels than controls (17.8+/-4.7 vs. 33.2+/-21.0 pmol/L respectively; p=0.004). There were no differences in estradiol, FSH or AFC. CONCLUSIONS: Women with CF have reduced ovarian reserve which may contribute to sub-fertility. CF care providers should consider referring women with CF to fertility specialists early to optimize chances of pregnancy.
