Introduction: In spite of many studies, the pathomechanism of dysmenorrhea (DM) remains unclear. The study aimed to evaluate the levels of progesterone and 17-beta estradiol and the severity of dysmenorrhea in six young women, including three after the use of manual therapy and the other three after the administration of ibuprofen. Material and methods: In six patients aged 22±2, gynecological and physiotherapeutic examinations were completed. Moreover, a two-fold determination of progesterone and 17-beta estradiol levels were carried out. The intensity of dysmenorrhea was assessed in the numerical pain rating scale (NPRS). The patients were dichotomized into two subgroups. Subgroup A (n=3) was subjected to manual therapy (3 x 45 min), while in subgroup B (n=3), the patients were administered ibuprofen 3 x 400 mg/24 h during menstruation. Results: Lower progesterone levels were detected in the blood of the 3 women from subgroup A after manual therapy and in 2 of the women from subgroup B after administrating ibuprofen. After the therapy, the level of 17-beta estradiol was higher in each woman from subgroup A and in one woman from subgroup B. In subgroup A, dysmenorrhea was reduced on average from 8 down to 3 points in the NPRS and duration time was shortened by one day on average. In subgroup B, dysmenorrhea was decreased on average from 8 to 3 points in the NPRS, yet no changes in its duration time were observed. Conclusions: It has been demonstrated that manual therapy alleviated dysmenorrhea to a similar degree as ibuprofen. However, only the manual therapy exerted an effect on the shortening of dysmenorrhea duration time. The use of manual therapy probably influenced the diminution of progesterone levels.
