Abstract

Purpose: In recent years, anti-Mullerian hormone (AMH) has been considered a reliable index of ovarian reserve. There are few data on AMH values in thyroid cancer. The aim of this study was to evaluate AMH levels in pre-menopausal women with a history of low-risk thyroid cancer. Methods: Thirty-four women (aged 40.7 ± 6.7 years) were studied 7.1 ± 0.9 years after surgery and at least one RAI treatment. A group of 23 thyroid cancer women (41.6 ± 7.4 years) who had undergone only thyroidectomy served as controls. AMH, follicle-stimulating hormone (FSH) and estradiol were assayed on days 2–3, and prolactin and progesterone levels on days 21–24 of the menstrual cycle. Results: Pregnancy (RAI group 62%; control group 61%) and miscarriage rates (18% and 26%) were similar. AMH levels were similar in the RAI (10.7 ± 1.7 pmol/l) and control (17.5 ± 4.7 pmol/l) groups. Regular menses were reported in 41% and 52% of RAI and control subjects, respectively. Non-ovulatory cycles were noted in 26% and 35% of RAI and control women, respectively. AMH levels were found to be negatively correlated with age (RAI group P = 0.0003; control group P = 0.0001) and FSH, and positively correlated with progesterone, but not with the other hormonal parameters. Conclusions: AMH should replace FSH in the evaluation of gonadal reserve in pre-menopausal thyroid cancer women. At present, age is the only predictor of AMH levels. About one out of two women with a history of thyroid cancer suffers from menstrual dysregulation, but infertility must be considered a low risk.
