seminal fluid test, any of several tests of semen to detect abnormalities in a male’s reproductive system and to determine fertility. Some common factors considered are seminal fluid liquefaction time and spermatic quantity, morphological characteristics, motility, volume, and pH. Normal values in some of these tests are as follows: sperm count, 60 million/mL to 150 million/mL of seminal fluid; pH, higher than 7 (7.7 average); ejaculation volume, 1.5 mL to 5.0 mL; and motility, 60% of sperm.
