The dilated lower part of the vas deferens of cestodes which opens into cirrus.
either of a pair of male accessory sex glands that open into the vas deferens before it joins the urethra. The seminal vesicles secrete most of the liquid component of *semen.
These are a couple of spongy glands, l.5 to 2 inches long, that secrete high-sugar, acidic, and thick, ropy colloid into the ductus deferens (containing sperm from the testes) during ejaculation. The two fluids empty into the prostate, where they are mixed with alkaline prostatic fluids to form semen.... seminal vesicles
analysis of a specimen of semen, which should be obtained after five days of abstinence from coitus, in order to assess male fertility. Normal values are as follows: volume of ejaculate: 2–6.5 ml; liquefaction complete in 30 minutes; sperm concentration: 20–200 million spermatozoa per ml (sperm count refers to the total number of spermatozoa in the ejaculate); motility: 60% moving progressively at 30 minutes to 3 hours; abnormal forms: less than 20%. Analysis of three separate specimens is necessary before confirming the presence of an abnormal result.... seminal analysis
