Uso de midodrín y congelación de semen en el tratamiento de las alteraciones del transporte espermático: caso clínico / Use of midodrine and frozen/thawed semen to treat semen transport disturbances: report of 2 cases

RESUMO

Retrograde ejaculation severely compromises male fertility. The use of sympathicomimetics for the treatment of this condition has poor results, except in patients with partial retrograde ejaculation, whose semen has a higher spermatozoa concentration. The semen of two patients with partial retrograde ejaculation was collected and frozen after the injection of a sympathicomimetic (Midodrine). The frozen/thawed samples were mixed with fresh semen recently ejaculated to obtain a minimal number of motile spermatozoa, and used for intrauterine insemination (> de 1 x 106 motile spermatozoa/ml). In both cases, pregnancies that developed satisfactorily, were obtained
