Effects of Supervised Physiotherapy-Based Exercise on Ovarian Reserve and Spontaneous Pregnancy in Women with Diminished Ovarian Reserve: A Controlled Pilot Study

Diminished ovarian reserve (DOR) is a major cause of female infertility with limited treatment options, and lifestyle interventions such as supervised, structured exercise therapy may support ovarian function. In this pilot study, we evaluated the effect of a supervised, physiotherapy-based exercise program combined with antioxidant supplementation on ovarian reserve markers and spontaneous pregnancy rates in 24 infertile women aged 20-42 years, with body mass index (BMI) 18.5-30 kg/m², regular menstruation, anti-Müllerian hormone (AMH) < 1.1 ng/mL, and antral follicle count ≥3 measured on days 2-4 of the cycle. Participants were randomized into two groups of 12: Both groups received standardized oral therapy, while the intervention group additionally participated in a three-month supervised, structured exercise therapy programme. Analysis of covariance was used to adjust for baseline differences in AMH and BMI, as groups differed significantly in BMI at baseline. At post-treatment assessment, AMH levels were significantly higher in the intervention group, whereas FSH, LH, estradiol, prolactin, and TSH levels did not change significantly. Spontaneous pregnancies were recorded both during the intervention period and throughout a follow-up period of up to six months. Spontaneous pregnancy occurred in 7 out of 12 participants in the intervention group versus 1 out of 12 in the control group, resulting in four and one live births, respectively. These findings suggest that combining supervised, structured exercise therapy with antioxidant supplementation may enhance ovarian reserve and improve the likelihood of spontaneous pregnancy in women with diminished ovarian reserve.
