Asthenozoospermia and Oligozoospermia Are Different, Remember These 3 Key Distinctions

Asthenospermia and oligospermia are both male disorders that may affect male fertility, but they have clear differences. It is believed that many men do not quite understand what the exact differences are.


So, how to identify these two diseases? Let's take a look.

1. Difference in concepts

Asthenospermia is a male disease in which less than 50% of the sperm move forward or less than 25% of the sperm are with class A motility in semen parameters, also known as low sperm motility. The so-called sperm with class A motility refers to sperm with excellent forward motility.

Oligospermia is a condition in which sperm density is less than 20×10^6 per milliliter in three consecutive, interrupted semen analyses while other parameters are normal or basically normal. However, oligospermia is often associated with low sperm viability, poor forward motility, and high sperm malformation rate.

2. Difference in diagnostic criteria

The diagnosis of asthenozoospermia mainly relies on testing sperm motility function. Before semen liquefaction, the motility of normal sperm is limited when they are separated from the semen. However, once the semen liquefies, the sperm will demonstrate good motility, especially forward movement capability. If the sperm's motility function is affected for some reason, causing the sperm to be unable to reach the location of the egg during the optimal timing, it will result in fertilization disorders.

The diagnosis of oligospermia is based on the measurement of the sperm count per milliliter of semen. If the sperm count per milliliter is less than 20 million, oligospermia is diagnosed. Depending on the specific sperm count, oligospermia is categorized into 3 grades: mild oligospermia, where the sperm count per milliliter is less than 20 million and greater than 10 million; moderate oligospermia, where the sperm count per milliliter is less than 10 million and greater than 5 million; and severe oligospermia, where the sperm count per milliliter is less than 5 million.

3. Difference in causes

The causes of asthenospermia include incomplete maturation or damaged thinning of the testicular spermatogenic epithelium so that it produces sperm of poor quality and weak motility; low semen volume; seminal plasma variants, for instance, when inflammation occurs in the epididymis, the seminal vesicles, or the prostate, etc., the conditions are not conducive to the activity and survival of sperm like the acidity and alkalinity, oxygen supply, nutrition, metabolism, etc.

In addition to congenital azoospermia and sperm deficiency, the causes of reduced sperm production or abnormal morphology and activity include the following main acquired factors: higher temperature in the pubic area, nutritional disorders, tobacco and alcohol damage, drug damage, diseases and testicular injury. In addition to taking medication as the doctor prescribes, patients with sperm deficiency should strengthen self-conditioning to help recovery.

Whether it is asthenospermia or oligospermia, countermeasures should be taken timely once diagnosed. For asthenospermia and oligospermia caused by male genitourinary tract infections, Diuretic and Anti-inflammatory Pill has a good therapeutic effect! It has the efficacy of clearing heat and removing toxins, promoting blood circulation and relieving pain, and inducing diuresis for treating stranguria. So it can help eliminate patients' symptoms and inflammation, improve men's physique, and enhance male fertility!

In addition, patients with asthenospermia or oligospermia can be conditioned by dietary modifications. Patients are advised to eat more foods rich in protein, vitamins, zinc and sex hormones because they are good for their conditions.


The question is frequently asked whether patients with asthenospermia or oligospermia can participate in In Vitro Fertilization(IVF). In fact, these patients can choose to reproduce through IVF. However, generally, mild symptoms will not affect male fertility, and in most cases, patients can recover their fertility through self-conditioning or medical treatment. Therefore, it is recommended to accept treatment first and consider IVF after unsuccessful treatment.
