Frequently asked questions

Does masturbation cause low sperm count?

No, it won’t have any long-term effect on your sperm quality or quantity. In fact, orgasms can release stress and reduce the likelihood of prostate cancer. Ejaculation can slightly lower sperm count for a few days and sperm count is lower right after ejaculation. Avoiding masturbation for a few days before trying to conceive may increase your changes.

How can I make sperm stronger?

Sperm ‘strength’ is related to shape, ability to move and numbers of live sperm released in semen. These can be improved either through medication or through lifestyle changes. See the information under the ‘What to do after testing positive for sperm problems?’ for details.

What makes a man super fertile?

There is no way of becoming super fertile’. Fertility rates can be affected by genetics, but also by lifestyle or health problems. Some men are naturally more fertile, but most men can achieve higher levels of fertility through treatment. You do not need to be more fertile than average to conceive a child.

Can a GP do a male fertility test?

Yes, your doctor can arrange a semen analysis. A GP will normally offer a sperm count check if you’ve been trying for a child unsuccessfully for 1 year. You will need to produce your sample for testing in person and then results are usually available within a week.

What colour and smell is healthy sperm?

Healthy semen is usually clear, white or grey and has the consistency of raw egg. Normal sperm is slightly alkaline, making it smell a bit like cleaning products containing bleach, chlorine or ammonia. Healthy sperm usually have a faint smell and stronger more unpleasant smells may be a sign of health problems.

See your GP or health professional if your semen:

  • becomes strong-smelling
  • smells fishy
  • contains blood
  • is coloured pink, red, brown, black, yellow or green

Or if you experience pain when ejaculating.
