Semen Defined

Semen is a blend of substances of which:

  • 30 to 35 per cent by the prostate
  • 5 per cent from the testicles and epididymes
Semen also contains over 50 different compounds (including hormones, neurotransmitters, endorphins and immunosupressants) each performing a different function and each found in differing concentrations within the seminal plasma. Semen also contains citric acid, free amino acids, fructose, enzymes, phosphorylcholine, prostaglandin, potassium, and zinc. Semen is a mixture of substances, all designed to encourage the male sperm to the female egg during sexual intercourse.The amount ejaculated ranges from a couple of drops to six milliliters.

A lot of different types of semen: normal gel, clear, stringy and opaque. The degree to which you are hydrated does have an impact sometimes on the amount and consistency of your semen.


Normal Semen:

Semen is usually a cloudy white or grey fluid. Following ejaculation, semen may thicken to a jelly-like consistency. Within 30 minutes, it typically becomes runny and clear. The thickening and liquefaction are thought to be important to reproduction. If often has a faint chlorine smell but foods for example, Asparagus can give semen a foul smell.


Post Vasectomy Reversal

We often hear people describe a colour change in semen after vasectomy reversal or the presence of blood.  Noticing the presence of blood represents the presence of thickened epididymal secretions clearing and is a good sign.  There is no specific treatment but please be reassured that this does not adversely affect the reversal and may indeed indicate that they are likely to have a positive result.


Clumps in semen

Rice like clumps are all perfectly normal are are nothing to worry about.
