Abstract:
Ovarian pregnancy is a rare subtype of ectopic pregnancy with an increased incidence after assisted conception. We present a 31-year-old gestational carrier who presented with suprapubic and pelvic pain at 6 weeks and 2 days' gestation. An ultrasound scan demonstrated an empty uterus and a complex mass in the left adnexa. Operative laparoscopy was performed and an ovarian pregnancy was found and treated. We believe this to be the first report of ovarian pregnancy after IVF in a gestational carrier. Appropriate counselling of surrogate mothers is of utmost importance as the risk of ectopic pregnancy is increased by using assisted reproduction technology. Although ovarian pregnancy still remains a rare event, the possibility of this condition should always be considered.

Electron Carriers
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...
Carrier Transport
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:

Carrier Generation and Recombination
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
