Oligospermia and Azoospermia are commonly used words when we talk about male infertility. Nevertheless, for many people, these words will be meaningless. In simpler words, oligospermia means “insufficient sperm”, whereas azoospermia means “no sperm at all”. Oligospermia and azoospermia, like many other medical terms, have a Greek origin.


Azoospermia is a condition of male infertility where there is a complete absence of sperm from the semen (fluid ejaculate). It affects about 1% of the male population and about 15% of the infertile couples.

Azoospermia could be caused by multiple issues. In cancer patients, who have undergone chemotherapy or radiation treatments, the cells that produce the sperm are killed. Hence the testicles will produce semen without sperm rendering the individual infertile. Azoospermia can also occur if there is any reproductive tract infection, groin injury or genetic conditions. This can lead to infertility issues. The most common cause is vasectomy which leads to blockage of the tubes that carry sperm from testicles to your penis. This is performed as a birth control measure for men who have completed their family. Here, the testes are making the sperm but it is blocked. Azoospermia may also be attributed to other factors such as obesity or age.


Oligospermia is a male fertility problem marked by a low sperm count. Other attributes of men with this condition’s sexual health are common. This encompasses the ability to obtain and keep an erection as well as ejaculate during orgasm.

The number of sperm in your seminal fluid can fluctuate throughout your life. An adequate number of healthy sperm is frequently required for fertility. Sperm counts of 15 million sperm per ml of sperm are considered average by the World Health Organization (WHO). Anything less is reported to be low and is referred to as oligospermia.

Types of Oligozoospermia

  • Mild oligozoospermia: Mild oligospermia is defined as having 10 to 15 million sperm/mL.
  • Moderate Oligozoospermia: 5 to 10 million sperm/mL is considered moderate oligospermia.
  • Severe Oligozoospermia: If sperm counts are between 0 to 5 million sperm/mL, serious oligospermia is diagnosed.

Causes of Oligospermia

  • Drugs/Alcohols
  • Tumours
  • Hormonal issues
  • Overweight
  • Exposure to harmful chemicals
  • Ejaculation issues due to medicines
  • Sexually transmitted infections


Treatment can increase the quantity and quality of sperm. Among these treatment options are:


Varicocele frequently necessitates surgery. Your doctor will close off the enlarged veins during the process. They will redirect blood circulation to a different vein.


Antibiotics and other medications are used to treat infections and inflammation. Treatment may not increase sperm counts, but it may halt the dips in sperm count.

Lifestyle Modifications

Losing and maintaining a healthy body weight could increase sperm count. It may also lower your risk of a range of other health problems. To improve sperm counts, avoid using drugs, alcohol, and tobacco.

Hormonal Therapy

Hormones can be restored to a healthy level using a range of drugs, injections, and lifestyle modifications. Sperm counts may increase as hormone levels return to normal.

Alternative Therapy

Stem cell therapy has emerged as a fresh hope for male patients due to their ability to self-renew and differentiate, stem cells have been proposed as therapeutic targets for a variety of diseases, including male infertility.
