Body Check – Semen Transcript

Dr Christian: When men ejaculate the purpose of their semen is probably the last thing on their minds but it serves a very important role. Semen is essentially there to carry and protect the sperm it contains but how it looks can change depending on your general well being.

It’s advisable to occasionally check your semen for anything out of the ordinary, as it could highlight another problem or condition in the body. There are a few simple things to look out for.

Usually semen is a cloudy white or off white fluid that within about 30 minutes outside the body goes runny and clear. Any difference in colour may be your body telling you there is a problem.

If the semen becomes predominantly yellow or tinged with green this could be a sign of infection, often due to the sexually transmitted disease gonorrhoea.

Red or brown semen could be a sign of a prostate problem like a burst blood vessel, an infection, an injury or in some cases cancer. So do speak to your doctor if the symptoms continue.

The amount of semen produced will vary from man to man and depends on how active a sex life he has. But on average it’s about a spoon full.

However, recurring low levels or watery semen could highlight a problem called retrograde ejaculation. With this condition, sperm is ejaculated into the bladder rather than out through the penis. It is not harmful but can cause fertility problems; or it could be sign of a prostate abnormality so is worth speaking to your GP about.

Semen will often have a chlorine type smell but a strong, foul smelling ejaculation is very likely to be a sign of an infection, and like all the other warning signs, should be examined by a GP.

For this body check and others featured on the site we want to hear about your findings so please come back to share your results and discuss them with other site users.

I know that loads of men find it very difficult to talk about these sorts of problems, but there are lots of treatments available so please talk to your GP if you are worrying.

Body Check: Semen

When men ejaculate, the purpose of their semen is probably the last thing on their minds, but it can serve a very important role in spotting changes in your well being. In this video, Dr Christian discusses what changes to look out for in your semen.

Usually, semen is a white or off white fluid that within about 30 minutes turns runny and clear. Any changes in colour or smell could be a sign of something more serious.

Semen will usually have a chlorine type smell, but a strong foul smelling ejaculation could be a sign of infection. Yellow or green tinged semen could also indicate infections and red or brown semen can highlight prostate problems.

The amount of semen produced varies from man to man. However, recurring low levels of watery semen could indicate a condition called retrograde ejaculation and though not harmful, it can cause fertility problems.

If you spot any of these changes contact your GP.

I'm guessing you're uncircumcised? It's probably smegma. You need to clean under your foreskin properly.

My boyfriend's seamen smells really quite strong and foul. We've been together for a few months and it has always been that way. At first I thought the smell was coming from me and started looking up bacterial vaginosis, but no, it's definitely coming from him. My previous two partners had seamen which didn't smell at all so I find it a bit odd. After sex, the stench of the fluid oozing from me can often fill the room. (Apologies for being so crude but this is embarrassing bodies). We could never go swinging cause it would be embarrassing. (not that we have any desire to). Anyway, from what he's said to me, I think he's had it all his life. What could cause it? Also, it smells stronger if he doesn't come for a few days. Why would this be?
