The most common complaint about ejaculation is too rapid or what is called "pre-mature ejaculation." This topic was discussed above in the orgasm section. Less commonly, men can have what is called retrograde or backward ejaculation. In this case, climax is reached, but no fluid comes forward out the end of the penis. Rather, a nerve malfunction has resulted in the fluid going backward into the urinary bladder, and the ejaculation fluid (semen) safely passes out the next time the man urinates. This is not a significant problem unless the man is trying to get his wife pregnant. In many cases simple medications can be used to stimulate the nerves to propel the semen forward so as to allow pregnancy through intercourse to occur. However, when this medicine fails, sperm can be successfully harvested by collecting the first urine sample voided immediately after climax. These sperm can be "washed" and concentrated in the laboratory to be used for insemination of the man's female partner.
