Sperm is a lightweight liquid that cannot overcome the density of water. Instead, it tends to <a href=\"https:\/\/sperm.blog\/does-fertile-sperm-sink-in-water-find-out-the-truth\/\" target=\"_blank\" rel=\"noreferrer noopener\">float and move<\/a> with the flow.

However it doesn&#8217;t lead to anejaculation, although it sometimes does, SSRI treatment appears to substantially improve perceived control over ejaculation when compared to placebo. Undesirable effects are a small increase in treatment withdrawals due to adverse events as well as substantially increased adverse event rates.
