However, women claiming to have ejaculations who have agreed to
urethral catheterization
prior to intercourse expelled large volumes of urine through the catheter at orgasm.

It is also important for physicians to distinguish orgasmic ejaculation from vaginal discharges which may require further investigation and treatment. In individual cases, the exact source of any reported discharge may not be obvious without further investigation.

Nature of fluid

Critics have maintained that ejaculation is either stress incontinence or
vaginal lubrication
. Research in this area has concentrated almost exclusively on attempts to prove that the ejaculate is not urine,

levels. Early work was contradictory; the initial study on one woman by Addiego and colleagues reported in 1981,

but was confirmed in another 7 women in 1984.

In 1985 a different group studied 27 women, and found only urine,
