A low sperm count, also called oligozospermia, is where a man has fewer than 15 million sperm per milliliter of semen.

Having a low sperm count can make it more difficult to conceive naturally, although successful pregnancies can still occur.Problems with sperm, including a low sperm count and problems with sperm quality, are quite common. The following steps should be taken by any man who is experiencing low sperm count.

Getting your sperm count checked

You will need to see your gynecologist if you have not managed to conceive after one year without success. It is a good idea for both you and your partner to get advice, as fertility problems can affect men and women and often could be a combination of both. It is important to understand what the exact issue is before you decide on your next steps.

One of the tests your Gynecologist can arrange you to go through is a semen analysis.This is where a sample of your semen is analyzed in a laboratory to check the quality and quantity of the sperm. The results are usually available within a week.If the results are abnormal, the test should be repeated to ensure it was accurate. This will normally be performed after three months.

Your GP can refer you to a specialist in male infertility at your local hospital or fertility clinic if any problems are found.

Home sperm count testing kits

There are several male fertility home-testing kits available to buy from pharmacies. These tests claim to indicate whether your sperm count is low.

It may be tempting to try one of the tests if you would rather not see your GP, but you should be aware that:

• although research by the manufacturers suggests these tests can give an accurate indication of sperm count, they haven’t been extensively studied

• some home-testing kits classify a low sperm count as under 20 million sperm per milliliter of semen, but more recent international guidelines state that anything above 15 million sperm per milliliter of semen is normal

• home-testing kits only check the number of sperm, not other things that can affect fertility, such as how well the sperm are able to move (motility)

While these tests might sometimes give a useful indication of your sperm count, they may also give you false reassurance or may suggest your sperm count is low when it’s actually perfectly normal.

It’s better to see your GP for a proper semen analysis at an accredited laboratory if you’re concerned about your fertility.

Causes of a low sperm count

In many cases, it is not obvious what causes a low sperm count.Sometimes problems with sperm count and quality are associated with:

• a hormone imbalance, such as hypogonadism (reduced hormone production)

• a genetic problem such as Klinefelter syndrome

• h a v i n g h a d undescended testicles as a baby

• a structural problem – for example, the tubes that carry sperm being damaged and blocked by illness or injury, or being absent from birth

• a genital infection s u c h a s c h l amy d i a , gonorrhoea or prostatitis (infection of the prostate gland)

• v a r i c o c e l e s (enlarged veins in the testicles)

• previous surgery to the testicles or hernia repairs

• t h e t e s t i c l e s becoming overheated

• excessive alcohol consumption, smoking and using drugs such as marijuana or cocaine

• certain medications, including testosterone replacement therapy, long-term anabolicsteroid use, cancer medications (chemotherapy), some antibiotics and some antidepressants

Treatments for low sperm count

If you or your partner has been diagnosed with a low sperm count, there are several options available. Your doctor may initially suggest trying to conceive naturally for a little longer. Many couples conceive within the second year of trying.

You can help maximize your chances of conceiving by:

• having sex every two or three days

• moderating your alcohol consumption and stopping smoking

• staying in good shape, exercising regularly and having a healthy, balanced diet

In Vitro Fertilization (IVF)

In Vitro Fertilization (IVF) may be an option if you have a slightly low sperm count and you havebeen trying to conceive naturally with your partner for at least two years.

During IVF, an egg is removed from the woman’s ovaries and fertilised with sperm in a laboratory. The fertilised egg is then returned to the woman’s womb to grow and develop.

Intracytoplasmic sperm injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is a type of IVF technique, in which a single sperm is injected directly into an egg to fertilise it. The fertilised egg is then transferred to the woman’s womb.

ICSI may be offered if you have been trying to conceive naturally with your partner for at least two years and you have either:

• few or no sperm in your semen

• poor quality sperm

Before having ICSI, you and your partner will need to have an assessment to ensure the treatment is appropriate. This will involve questions about your medical and sexual history, and screening tests to check for infections or genetic problems that could affect your baby and the chances of ICSI working.

Donor insemination

Donor insemination means using sperm donated by another man.You may wish to consider using donor insemination as an alternative to ICSI, particularly if the man has a genetic disorder that could be passed on to any children. It can be used as part of IVF if necessary. If you are considering donor insemination, you should be offered counseling as a couple about the implications for you and your children.

Gonadotrophin medication

If you have very low levels of gonadotrophin hormones (which stimulate the production of sperm), you should be offered treatment with gonadotrophin medication to improve your fertility.But if no cause has been found for your abnormal sperm count, you will not be offered hormone-based medicines as they are not known to improve fert
