Oviduct prostacyclin functions as a paracrine factor to augment the development of embryos.

Background: Recently we discovered that human oviducts produce a significant amount of prostacyclin (prostaglandin I2, PGI2) and that PGI2 enhances the potentials of live birth of mouse embryos. However, the eicosanoid profile of mouse oviducts remains unknown.

Methods: The metabolites of [14C]arachidonic acid by mouse oviducts were analysed by high-performance liquid chromatography.

Fetal macrosomia (> or =4500 g): perinatal outcome of 231 cases according to the mode of delivery.

Objective: To determine perinatal complications in infants >or = 4500 g according to delivery mode.

Study Design: Records of 231 mothers and live cephalic infants weighing >or = 4500 g over a 13-year period were retrospectively reviewed. Maternal and perinatal complications were compared in relation to delivery mode.

Impact of advanced maternal age on pregnancy outcome.

The aim of this study was to compare the pregnancy outcome and delivery complications in women 40 years or older (cases) to that of women 20 to 30 years old (controls). Over a 5-year period, 319 cases had a singleton delivery in our institution. These women were compared with 326 controls.
