Retrograde ejaculation: etiology and treatment via the use of a new noninvasive method.

ABSTRACT

Retrograde ejaculation (RE) is not a common infertility problem, but has increased in incidence recently due to surgical aggressiveness in pelvic and genital malignancies. However, RE is the most common cause of aspermia, or absence of ejaculate at orgasm. Meanwhile, surgical or drug therapy methods have not been very promising in regaining normal antegrade ejaculation. As yet, the standard procedures for treatment of RE involve the artificial insemination of either nonprocessed or processed (via centrifugation and resuspension) postcoital voided bladder contents. RE specimens in this study were collected after postcoital voiding into a TEST buffer and resuspended in TEST-yolk buffer. The urine effects on the voided spermatozoa were studied. The technique employed in this study assists in the recovery and reconstitution of RE fit for artificial insemination.
