To the Editor:

We read with interest the Androlog Summary by Chudnovsky and Niederberger on "Copious Pre-ejaculation: Small Glands—Major Headaches" (J Androl, 2007;374–3755). In this article, they cited our study (Zukerman et al, 2003) and stated that we "observed the presence of spermatozoa in pre-ejaculatory fluid and have advocated against the use of coitus interruptus as a safe means of contraception." Ironically, our findings and conclusions were actually the opposite. We studied 12 subjects who were referred to our Andrology and Sex Counseling Unit for the following reasons: 1) 3 for excessive fluid secreted during foreplay, 2) 5 for premature ejaculation, and 3) 4 normal healthy volunteers. Whereas all patients had sperm in routine sperm analyses, none of the pre-ejaculatory samples contained sperm. We therefore concluded that because pre-ejaculatory fluid secreted at the tip of the urethra from the Cowper gland during sexual stimulation did not contain sperm, the failure of coitus interruptus as a contraceptive method is probably due to late withdrawal (after emission and onset of ejaculation).
