Uterorelaxing effects of vaginal progesterone: comparison of two methodologies for assessing uterine contraction frequency on ultrasound scans Jean-Marc Ayoubi, M.D., Renato Fanchin, M.D., Delphine Kaddouz, M.D., René Frydman, M.D., Dominique de Ziegler, M.D. Fertility and Sterility Volume 76, Issue 4, Pages 736-740 (October 2001) DOI: 10.1016/S0015-0282(01)01998-7
FIGURE 1 Uterine contraction (UC) frequency: Three-dimensional (3D)-derived assessment. UC frequency was assessed daily using a 3D-derived technique from day 15 to day 20 in estrogenized women receiving 1.125 g of Crinone 4% or 8%, and 2.25 g of Crinone 8% containing 45, 90, and 180 mg of P, respectively.

FIGURE 2 Uterine contraction (UC) frequency during the folliculoluteal transition. The results of UC frequency measured on accelerated sequences (×2–5) of images sequences and with the three-dimensional (3D)-derived methodology are comparable. Ayoubi.
