Ovarian reserve in patients with Sjögren’s syndrome: a cross-sectional study

Objective This study aimed to assess the potential impact of primary Sjögren’s syndrome (pSS) on fertility and ovarian reserve by evaluating the number of antral ovarian follicles (AFC) through ultrasound and analysing serum levels of anti-müllerian hormone (AMH) and follicle-stimulating hormone (FSH), which are currently the most reliable indicators of fertility potential. Method A total of 52 premenopausal women were recruited from the Maternal, Infantile, and Urological Sciences Department at Umberto I Hospital, Sapienza University of Rome. Among them, 26 had pSS, and 26 served as healthy controls. All participants underwent a gynaecological examination, a transvaginal ultrasound, and serum testing for AMH and FSH levels. Results The study found that serum AMH levels were significantly lower ( p = 0.002) in pSS patients compared to the controls, indicating a potential reduction in ovarian reserve in these patients. However, no statistically significant differences were observed in FSH levels between the two groups. Conclusions The findings suggest that pSS may have a negative impact on ovarian reserve, as evidenced by lower AMH levels in comparison to age-matched controls. AFC and FSH levels, however, were similar to those of healthy women. These results provide new insights that could be beneficial for this patient population, though further, larger-scale studies are necessary to more comprehensively understand the relationship between pSS and female fertility. Key Points • The study assesses the possible impact of pSS on fertility and ovarian reserve by evaluation of AMH, FSH, and AFC. • Family planning and fertility are important issues for patients with rheumatic disorders and must be considered and discussed with the patient already at the time of diagnosis, and appropriate counselling must be performed.
