Azoospermia is a condition that occurs when there is no sperm in the semen.
Either your testicles fail to produce sperm or something stops sperm from mixing up with semen. There are three main causes that can be identified.
Aspermia is a condition that happens when there is no semen (Seminal fluid) in the ejaculation.
Retrograde ejaculation is one of the main cause of Aspermia where semen is redirected to the bladder instead of the urethra (The tube that carries urine and ejaculation). Other causes may be
In contrast to Azoospermia, Aspermia can be identified by the lack of semen when ejaculating (Anejaculation). Other signs are as follows.
Teratozoospermia is a condition when sperms have abnormal forms and structures (Morphology). Awing to this abnormality, properly penetrating a fertile egg is difficult and therefore it causes subfertility.
Exact reasons for this disorder is unknown. However, the following are considered viable causes.
This disorder cannot be identified on the outset but a proper analysis of semen samples. Persons with subfertility must consult a reputed ayurvedic physician for further evaluations.
Sperms should be able to move independently (Motility) to be able to successfully penetrate a fertile egg. Asthenozoospermia is a condition used to classify sperms with no motility. Sperms with no or limited motility directly affect fertility.
The exact cause for Asthenozoospermia cannot be ascertained. Probable causes are as follows.
This disorder cannot be identified on the outset but a proper analysis of semen samples. Persons with subfertility must consult a reputed ayurvedic physician for further evaluations.
Men with hyperspermia produce larger semen volume than the average. This condition is defined as having a semen volume of 6.0 to 6.5 ml. (reference). Although men with this condition have higher libido (sex drive), it could affect their fertility.
Hyperspermia is a rare condition and therefore there are not enough researches conducted to deduce an exact cause. Following, however, are considered probable cause.
You don’t need to be alarmed because of higher semen volume. As long as your ejaculation contains a decent sperm count it doesn’t affect fertility. Following are general signs of this condition which must further be evaluated by a doctor.
Hypospermia is the opposite condition of Hyperspermia where affected men produce a low volume of semen (< 1.5ml) than an average amount. This combined with low sperm count (oligospermia) contributes to subfertility.
Lifestyle and pathological issues contribute to hypospermia. Following are the probable causes for this condition.
Low level of semen volume even after a few days of abstinence period is a sign of hypospermia. This condition can be cured with proper treatments.
Oligospermia is a condition characterised by lower sperm count than the average amount. The average sperm count is 15 million sperm per millilitre of semen. At least 60% of those sperms should have proper shape and motility.
It is further categorised into three categories based on the sperm count
The contributing factors to Oligospermia may include, but not limited to the following.
The main symptom of Oligospermia is the inability to conceive a child. Further tests are needed to diagnose. Although causes such as hormonal imbalance, dilated testicular veins and blockages may show symptoms.
Symptoms might include but not limited to
Necrospermia is a condition when either all or a high percentage of sperms are dead in a given semen sample. This is different from Asthenozoospermia in which sperms are immobile but not dead.
As with most male subfertility diseases, the exact causes are unknown due to the scarcity of the condition. The following factors, but not limited to, may contribute.
Both Asthenozoospermia and Necrospermia are potential causes of male subfertility. There are usually no symptoms and signs rather than the inability to conceive. The only way to diagnosis the problem is with a carefully carried out semen test.
