[3 new cases of internal male pseudohermaphroditism].

The authors report 3 new cases of Male Internal Pseudohermaphrodism. It is a scarce entity. The discovery is fortuous during the cure of hernia or cryptorchidism. The family history has nothing particular. The main problem of this syndrome is its treatment. Our attitude consisted in conserving the mullerian derivatives and treating the hernia or the cryptorchidism. Hysterectomy is not justified for the following reasons; no case of cancerisation of the mullerian derivatives has not yet been reported. The vasa deferens and uterus are in intimate relationship; the dissection is therefore dangerous. We did not perform systematic castration in order to protect fertility. The removal of the testis is performed only when the gland is intraabdominal and undescendable considering the major risk of cancerisation.
