J Reprod Infertil. 2014 Jan;15(1):41-8.


Background: Primary dysmenorrhea is a prevalent disorder and its unfavorable effects deteriorates the quality of life in many people across the world. Based on some evidence on the characteristics of fenugreek as a medical plant with anti-inflammato-ry and analgesic properties, this double-blind, randomized, placebo controlled trial was conducted. The main purpose of the study was to evaluate the effects of fenugreek seeds on the severity of primary dysmenorrhea among students.

Methods: Unmarried Students were randomly assigned to two groups who received fenugreek (n = 51) or placebo (n = 50). For the first 3 days of menstruation, 2-3 capsules containing fenugreek seed powder (900 mg) were given to the subjects three times daily for two consecutive menstrual cycles. Pain severity was evaluated using a visual analog scale and systemic symptoms were assessed using a multidimensional verbal scale.

Results: Pain severity at baseline did not differ significantly between the two groups. Pain severity was significantly reduced in both groups after the intervention; however, the fenugreek group experienced significantly larger pain reduction (p < 0.001). With respect to the duration of pain, there was no meaningful difference between the two cycles in the placebo group (p = 0.07) but in the fenugreek group, the duration of pain decreased between the two cycles (p < 0.001). Systemic symptoms of dysmenorrhea (fatigue, headache, nausea, vomiting, lack of energy, syncope) decreased in the fenugreek seed group (p < 0.05). No side effects were reported in the fenugreek group.

Conclusion: These data suggest that prescription of fenugreek seed powder during menstruation can reduce the severity of dysmenorrhea.
