Hi there,

Thanks for your question. If I don't respond immediately, it is because I am either in the OR or traveling. I will get back to you ASAP.

Technically, sex can cause a false elevation in the PSA for about 3-5 days. To be safe, we ask patients to refrain from sex for 7 days before having the PSA checked. Hope this helps and let me know if you have questions.
