The biochemical pregnancy loss rate remains stable up irrespective of age and differs in pattern from clinical miscarriages.

Introduction: As women age, the increasing rate of aneuploidy lead to an augmentation in the incidence of clinical miscarriages. It was anticipated that biochemical pregnancy rates would also rise with maternal age. However, no study has previously evaluated the effect of maternal age on biochemical pregnancy rates.

Broadband field-of-view expansion using a pair of digital micromirror devices.

Broadband field-of-view expansion using computational optics methods is presented. A pair of chirp gratings, implemented by digital micromirror devices, is placed on the optical entrance pupil plane of an optical system. The gratings perform achromatic translations of the image across the camera, and a wide image is reconstructed by a post-processing procedure.
