Worth of note: All women in the series are prevented from getting pregnant, until permitted by the authorities. This is achieved by insertion of a birth control device. Insertion of the device is never shown, but removal of the device is shown at 9:00 in S1E1. It becomes clear that the device is inserted and removed via an incision in the side of the abdomen, however in the removal scene it would be easy to believe that it was being removed by the doctor via the vagina. Later in the same episode (36:20) a woman is shown to have removed her own device by cutting into the side of her abdomen. The practice of forced birth control is mentioned several times in series, but only physically shown in the first episode.
