What Is Oligoasthenozoospermia? – Causes & Treatment

By (medical director at fertty international), BSc, MSc (embryologist) and BA, MA (fertility counselor).
Last Update: 05/25/2020

Oligoasthenozoospermia (OA), also called oligoasthenospermia, is a primary cause of male infertility where two seminal parameters are altered: sperm count and sperm motility.

Thus, oligoasthenozoospermia is the resulting disorder when oligozoospermia and asthenozoospermia are combined, which aggravates infertility in the male affected.

Achieving natural pregnancy with oligoasthenozoospermia is complicated, but the good news is that it is possible. Moreover, when conceiving is not possible, these couples can turn to reproductive technologies like In Vitro Fertilization (IVF) to become parents.


Oligoasthenozoospermia or oligoasthenospermia (OA) is a sperm disorder that involves two disorders at the same time:

Low sperm count, below 15 million sperm/ml.
Abnormal sperm motility, with more than 60% of sperm being immotile, or unable to move in a straight direction.

In short, males with OA have a reduced sperm motility and count, with sperm that are unable to move forward, with a rapid, linear progression.

As a result of this sperm disorder, the chances for sperm to hit the egg for fertilization are considerably reduced, which hinders or prevents natural pregnancy, causing male infertility.

Oligoasthenozoospermia is a condition where the male has less than 15 million sperm per milliliter. Moreover, 60% of spermatozoa are unable to move forward.


Establishing a unique cause of OA is difficult. As a matter of fact, it typically goes unnoticed by the man who suffers from it until he decides to have a baby.

In any case, the following are some of the most common causes of OA in men:

  • Toxic habits, including tobacco, alcohol, or drug use
  • Exposure to toxic environmental agents
  • Infections of the seminal ducts
  • Not following a balanced diet
  • Cancer treatments (radiotherapy and chemotherapy)
  • Hormonal imbalances
  • Testicular trauma
  • Testicular disorders, like varicocele
  • Genetic diseases, including Klinefelter syndrome (KS), or Y chromosome microdeletion

Altered sperm parameters can be caused by a combination of these factors as well.

Lifestyle plays a major role when it comes to determining sperm quality. Any alteration that affects spermatogenesis (sperm production process) can cause OA or any other sperm disorder.


Depending on the severity of OA, or if there exist other fertility issues in the man and/or the woman, the best treatment option will be different.

Broadly speaking, there is no cure for oligoasthenozoospermia. However, in the mildest cases, a simple change of lifestyle habits, and the intake of vitamin and antioxidant supplements can boost sperm quality.

Conversely, in the most severe cases, couples have no alternative but to undergo fertility treatment to become parents.

Natural treatment

Natural remedies to cure OA include following a healthy, balanced diet, quitting toxic habits, and adding supplements to your diet such as Androferti.

Androferti and any other male fertility product to boost male fertility, is composed of L-Carnitine, Vitamin C, coenzyme Q10, vitamin E, zinc, folic acid, selenium, and vitamin B12.

Other examples of natural remedies are: brewing damiana herb into tea, or Peruvian maca powder. The efficacy of these methods has not been scientifically proven, though.

Assisted reproduction

In severe cases of OA, or when the couple fails to achieve pregnancy naturally, the only option left for them to start a family is Assisted Reproductive Technology (ART).

Basically, there exist two fertility treatments that are adequate for these males:

Intrauterine Insemination (IUI)
Only indicated in cases of mild-to-moderate O, since there are a series of minimum quality standards to meet for IUI to be possible. The motile sperm count (MSC) after sperm capacitation must be 3 million sperm or more. There are some requirements for the woman as well, such as age and tubal patency.
In most cases, it is used as the first choice, especially in men with moderate or severe OA. Out of the sperms selected, they are injected into the egg one by one so that fertilization hopefully occurs.

Thanks to in vitro fertilization, all the obstacles present in the male and female reproductive tracts are overcome, thereby increasing the chances of achieving a pregnancy. In this particular case, by barriers we are referring to the cervix, uterus (womb), and Fallopian tubes.

Furthermore, with ICSI, the specialist can "force" fertilization to the point of even using a sperm that is immotile. The only requirement for this technique to be possible is that its integrity is intact, which is to say, that it is alive.

If you need to undergo IVF to become a mother, we recommend that you generate your Fertility Report now.

Is it possible to achieve pregnancy with oligoasthenozoospermia?

By Dr. María Arqué (medical director at fertty international).

Oligoasthenozoospermia is a cause of male infertility in which two seminal parameters are affected: sperm’s concentration and motility.

We talk of oligoasthenozoospermia when concentration is below 15 million per ml and when there are more than 60% of sperm with altered motility.

Therefore, oligoasthenosperma is considered to be a combination of the oligozoospermia and asthenozoospermia disorders, which aggravates men’s sterile situation.

Achieving a natural pregnancy by men with oligoasthenozoospermia is complicated, although not impossible. If pregnancy was not achieved, couples affected by this pathology should resort to in vitro fertilization (IVF) techniques in order to become parents.

Basically, there are two suitable treatments for these patients: Intra-uterine insemination (IUI) in cases of discreet oligoasthenozoospermia or IVF/ICSI for patients with moderate or severe oligoasthenospermia.

Can acupuncture help with severe oligoasthenozoospermia?

By Zaira Salvador BSc, MSc (embryologist).

Some studies have shown that acupuncture can indeed help with infertility in both males and females. Some men can experience an improvement in sperm quality after various acupuncture sessions, along with healthier lifestyle habits. However, in severe cases, it is unlikely that natural remedies help recover fertility in the male and allow him to conceive.

Can oligoasthenozoospermia be cured with Clomid?

By Zaira Salvador BSc, MSc (embryologist).

It depends on what is causing oligoasthenozoospermia (OA). The main ingrediente of Clomid is clomiphene citrate. This formula stimulates the function of the testicles, promoting spermatogenesis in males with hormonal imbalances. For example, Clomid would be the treatment of choice in cases of males with hypogonadism.

Is there a relationship between varicocele and oligoasthenozoospermia?

By Zaira Salvador BSc, MSc (embryologist).

Yes. Varicocele is a cause of low sperm quality, which can lead to sperm disorders such as oligoasthenozoospermia. In this case, sperm quality will increase after undergoing surgery to treat varicocele.
