Amarum) as an antifertility on pregnancy in the preimplantation stage of mice (Mus musculus L.). This study uses a Completely Randomized Design (CRD) consisting of 4 treatments. 16 female mice weighing 20-30 grams aged 2-3 months were divided into 4 groups, namely; K1 (Aquades), K2 (0.7 mg / g bb), K3 (1.4 mg / g bb), and K4 (2.8 mg / g bb) extract. The administration of the extract was administered orally as much as 0.5 ml / head / day in the 0 to 3 day pregnancy. Mice are maintained until the 18th pregnancy day. Mice were sacrificed and dissected, then the preimplantation stage pregnancy parameters were observed. The results showed that the white ginger rhizome extract reduced the percentage of implantation, namely K1 (0.90%), K2 (0.39%), K3. Reducing the percentage of resorbsi embryos, namely K1 (0%), K2 (0%), K3. Reducing the percentage of live fetuses, namely K1 (0.90%), K2 (0.35%), K3. As well as increasing the percentage of dead fetuses K1 (0%), K2 (0.04%) K3 and in the fourth parameter for K4 no fetus was found, the extract also increased the percentage of gestational loss, namely K1 (0.12%), K2 (0.60% ), K3 (1%) and K4 (1%).
