[Per-urethral coitus. One case followed by pregnancy]

Description of a case of intravesical coitus via the urethra in a woman with vaginal atresia with a punctate orifice, initially unnoticed. Pregnancy may occur by external insemination, despite this anatomical situation. Incontinence was worsened by hymenotomy and by the pregnancy. Incontinence without cystitis is the fact noted most frequently in the 18 cases found in the literature.
