1. Odor: Semen has a special fishy smell similar to carob or chestnut flowers. If there is an abnormal smell, further examination is required to determine the true cause. How is infertility caused by seminal vesiculitis diagnosed? 90% of semen is secreted from the seminal vesicle, and fructose can be used by sperm as a source of power; when the seminal vesicle is inflamed, these secretions decrease, which may affect the vitality of the sperm; insufficient volume of semen cannot fill the posterior fornix of the vagina with semen pool, which can also cause infertility. So how is infertility caused by seminal vesiculitis diagnosed? Below, experts from the best infertility hospital will introduce the diagnostic methods for infertility caused by seminal vesiculitis.
2. Appearance: Mainly observe the color of the semen, common colors include gray-white, milky white, light yellow, and brown-red. Normal semen is gray-white or milky white. If the semen is dark yellow, it is mostly due to abstinence for too long. If seminal vesiculitis or reproductive tract inflammation occurs, the semen can appear brownish red, also known as hematospermia.
3. Liquefaction of semen: Freshly ejaculated semen is thick and gel-like, and after 10-30 minutes, it becomes a thin liquid. This condition is called semen liquefaction. If the semen does not liquefy within one hour at a room temperature of 25°C, it is considered abnormal liquefaction.

What are the routine tests for sperm and semen?
Experts from Taiyuan Infertility Hospital introduce that generally, routine tests for sperm and semen include appearance, odor, acidity and alkalinity, liquefaction of semen, and volume of semen. Routine tests for sperm and semen can provide information on the volume of semen, sperm density, total number of sperm in the semen, sperm morphology, sperm motility and survival rate, sperm agglutination, and liquefaction of semen.
5. Acidity and Alkalinity: The pH value of semen is usually between 7.0-8.0. When the environment is too acidic (pH value less than 7) or too alkaline (pH value greater than 9), the vitality of the sperm will be greatly reduced, making conception difficult.

Infections are most commonly caused by Escherichia coli, followed by Staphylococcus, Streptococcus, and Corynebacterium-like bacteria. When the seminal vesicle is inflamed, the mucosa of the seminal vesicle becomes congested and edematous, and the gland cavity may become obstructed due to inflammation, forming an abscess. The seminal vesicle abscess may spread to surrounding tissues and invade adjacent tissues after breaking through the seminal vesicle.
4. Volume of semen: Normally, the volume of semen per ejaculation is 2-5 milliliters, less than 1.5 milliliters or more than 8 milliliters is considered abnormal.
Seminal vesiculitis can be divided into acute and chronic types. Seminal vesiculitis often occurs together with prostatitis. When diagnosing, it can be quite difficult to strictly distinguish between prostatitis or seminal vesiculitis. Seminal vesiculitis often affects both sides, and the inflammation is mostly caused by bacterial retrograde infection along the vas deferens from the posterior urethra or bacteria from epididymitis invading the seminal vesicle along the vas deferens.
