Reproductive hormones and anthropometry: a follow-up of PCOS and controls from perimenopause to above 80 years of age.

There is a lack of knowledge about hormonal and anthropometric changes in women with polycystic ovary syndrome (PCOS) after the menopause.To study reproductive hormones and anthropometry in women with PCOS up to an age above 80 years.Prospective cohort study.University Hospital.A well-defined cohort of women with PCOS, previously examined in 1987 and 2008 (21 years period) was re-examined in 2019 (11 years period). Of the original cohort (n = 37), 22 women were still alive and 21 (age range 72-91 years) participated. Comparisons were made with age-matched controls (n = 55) from the original control cohort (BMI similar to PCOS women). The results were compared with results from 1987 and 2008.Hormonal measurements and physical examination.FSH, LH, testosterone, SHBG, free androgen index (FAI), hirsutism score, BMI, and waist-hip ratio (WHR).At mean age 81 years, FSH levels were lower in women with PCOS (50 vs. 70 IU/L) who were still more hirsute than controls (33% vs. 4%). No differences were found in FAI, testosterone, SHBG or LH levels, BMI or WHR.From perimenopausal age until the present age, levels of testosterone and FAI continued to decline in women with PCOS. SHBG levels continued to increase with age. FSH had not changed over time during the last eleven years.Women with PCOS at ages 72-91 had lower FSH levels, remained clinically hyperandrogenic and had similar FAI and body composition as controls.
