Abstract
BACKGROUND AND OBJECTIVE: Polycystic ovarian syndrome (PCOS) is the common cause of
Oligo‑ovulation. This syndrome causes long‑term metabolic issues as well as increase the risk of
diabetes type 2, hypertension, dyslipidemia, and cardiovascular disease. The current research aimed
to study the effect of green tea on weight and hormonal changes of women suffering from PCOS.
METHODS: This two group, double‑blind, randomized clinical trial was conducted in Isfahan city.
Overweight women suffering from PCOS (n = 60) were randomly divided into two groups. Green
tea was prescribed to the experimental group, and placebo was prescribed to the control group.
Free testosterone hormones and fasting insulin were compared in both groups at the beginning and
12 weeks after the study commencement. The weight of participants of both groups was also measured
before and after the study. The statistical data were analyzed by SPSS software and paired t‑test.
RESULTS: The paired t‑test showed that there was no significant difference in the mean weight
of both groups before the intervention (P = 0.812), but the difference was significant after the
intervention (P = 0.031). There was no significant difference in the mean fasting insulin of both groups
before the intervention (P = 0.352), but the difference was significant after the intervention (P < 0.0001).
Moreover, there was no significant difference in the mean free testosterone level of both groups before
the intervention (P = 0.638), but the difference was significant after the intervention (P < 0.0001).
CONCLUSION: The consumption of green tea by overweight and obese women suffering from PCOS
leads to weight loss, a decrease in fasting insulin, and a decrease in the level of free testosterone.
