Abstract
Background
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age and the most common cause of infertility due to anovulation. PCOS in adolescents is concerning. Nigella sativa is effective in improving gonadotropins and sex hormones. The current study was designed to investigate the effect of Nigella sativa supplementation on PCOS symptoms and their severity in adolescents.
Methods
The current randomized clinical trial was conducted on 114 adolescents with PCOS who were referred to gynecologist offices and clinics in Gonabad, Iran from March 2022 to March 2023. Participants were randomly allocated to the intervention (Nigella sativa 1000 mg/day) and control (10 mg/day medroxyprogesterone from the 14th day of the cycle for 10 nights) groups. The study duration was 16 weeks. Ovarian volume (measured by ultrasound), anthropometric and blood pressure; serum testosterone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), luteinizing hormone (LH), hirsutism severity (Ferriman–Gallwey score) levels were evaluated before and after the study.
Results
Data from 103 participants (control group = 53, intervention group = 50) were analyzed. The mean age of participants was 17.0 (Interquartile range [IQR]:2.0). The mean difference in hirsutism score changes (p < 0.001), right (p = 0.002), and left (p = 0.010) ovarian volume, serum LH (p < 0.001) and testosterone (p = 0.001) were significantly higher in the intervention group compared to the control group. The frequency of oligomenorrhea, menometrorrhagia, and amenorrhea, were significantly reduced after the study in the intervention group compared to the control group (ps < 0.001).
Conclusions
Short-term Nigella sativa supplementation may be effective in reducing ovarian volume and improving hormonal balance, and menstrual irregularities in adolescents with PCOS. Further research and long-term studies are warranted to validate the potential therapeutic effects of Nigella sativa in adolescents with PCOS.
