Mode of delivery of women with Swyer syndrome in a German case series.

Objectives For women with Swyer Syndrome, a 46,XY gonadal dysgenesis, full term pregnancies are possible after oocyte donation. According to literature, mode of delivery is almost always by Caesarean section for various reasons. Medical indications are multiple pregnancies and related complications, preeclampsia, an androgynous shaped pelvis and failed induction of labor. Elective Caesarean sections were performed based on maternal request and medical recommendation. Methods Following careful examination and shared decision making, we planned a spontaneous delivery with a patient with Swyer syndrome and tested the different hypotheses regarding anatomical and functional features according to literature. In addition, deliveries of women with Swyer Syndrome were analyzed in a German multicenter case series. Results A total of seven women with Swyer syndrome with a total of 10 pregnancies were identified, who later gave birth to twelve live-born children. Seven out of 10 births were performed by elective and non-elective Caesarean section, three births took place vaginally. Conclusions In summary, the risk of Caesarean section delivery has increased, but spontaneous delivery can be attempted in the event of inconspicuous findings.
