Joseph, thank you for your question.

I get this question a lot, as does Dr. Drew, who you might know from Loveline. The answer to your question is YES! The secretion I think you’re referring to is the cowper’s gland secretion, and it is chock full of sperm. If you’re like most people, you’re wondering how that could be. Here’s why:

Sperm can survive in the male duct work for quite some time. As the sperm get moved along for an ejaculation, some of them stay behind, getting caught in crevices in the ductules and the like. What ends up happening is that the next time there is arousal and some preejaculatory secretion occurs, the sperm get trapped in the fluids, and enrich the fluid.

These sperm are just as capable of impregnating a woman as any other sperm.

Thank you for your question. If you have any other questions feel free to drop them by.
