Semen non-liquefaction means the ejaculate stays thick and jelly-like longer than the normal 15-30 minutes, making it hard for sperm to swim. The problem is silent at climax but shows up later.

The main sign is a thick, sticky gel that persists. Instead of turning watery, the sample stays like jam on the fingers or tissue.

Small clumps or grains may be visible. They look like tiny tapioca pearls mixed into the fluid.

Volume often looks normal, so the issue is noticed only when the gel is still there an hour later.

Some men feel a mild drag or heaviness in the pelvic floor after sex, as if the fluid is “stuck” inside.

Fertility trouble can be the first clue. Couples may try for months without success, and a lab test then reveals the thick sample.

There is usually no pain, smell, or color change—only the texture and timing are off.
