The effect of luteal-phase support with vaginal progesterone on pregnancy rates in gonadotropin and clomiphene citrate/intra-uterine insemination cycles in unexplained infertility: A prospective randomised study.

The purpose of this study is to analyse the effect of luteal-phase support on pregnancy rates in gonadotropin + intra-uterine insemination (Gn/IUI) and clomiphene citrate (CC) +IUI (CC/IUI) cycles in patients with unexplained infertility. Equal numbers of patients were recruited in two treatment arms (CC/IUI and Gn/IUI) (n = 100, n = 100, respectively). In each group, 50 patients received vaginal progesterone for 14 days (Crinone 8% vaginal gel, 90 mg per day) for luteal-phase support from the day after IUI and continued until menstruation or the 10th week of gestation if pregnant.

Finding the best formula to predict the fetal weight: comparison of 18 formulas.

Background: To compare the accuracy of 18 formulas in predicting fetal weight and also to make a comparison of these formulas in low-birth-weight fetuses (<2,500 g) and in fetuses weighing >4,000 g.

Methods: Four-hundred-and-ninety-five pregnant patients were enrolled. The estimated fetal weight was calculated using 18 different formulas.
