Sperm Abnormalities as defined by WHO
Kind of Sperm Abnormalities
Kind of sperm abnormalities Include:
Aspermia
This condition may be the result of retrograde ejaculation, genetic disorders like cystic fibrosis or Klinefelter syndrome, hormonal imbalances or congenital abnormalities. This condition may affect male fertility.
Hypospermia
In such conditions, the total ejaculate is less than 1.5 milliliters. Retrograde ejaculation is the most common cause of this condition. However, it may also be caused by genetic disorders, hormonal imbalances or congenital abnormalities.
Azoospermia
This is a condition wherein a man releases semen that contains no sperm during an orgasm. It is a severe type of male infertility. It may be caused by genetic disorders, hormonal imbalances, congenital abnormalities, untreated STDs and because of post-testicular cancer treatment.
Oligospermia
This is a condition wherein the man may have a low sperm count as well as problems with sperm shape and sperm movement. This may be caused by a varicocele vein, hormonal imbalances, undescended testicles, infections of the reproductive tract and environmental conditions.
Asthenozoospermia
This is a condition where a large percentage of sperm moves abnormally i.e., it doesn’t move in a straight line or does not move at all. This condition may be accompanied by a low sperm count. Some of the causes of this include exposure to toxins, excessive alcohol consumption, infections and side effects of certain medications.
Teratozoospermia
In this condition, the majority of the sperm in the semen are shaped abnormally. The sperms may have more than a single head or tail or an oddly shaped head. This keeps them from moving normally and affects their ability to fertilize an egg.
Oligoasthenoteratozoospermia
In such cases the shape, size and movement of the sperm are abnormal. The sperm count may also be lower than normal. This is the most common cause of male infertility.
Necrozoospermia
In such cases all the sperms in the semen are dead. It is a rare cause of infertility.
Leukocytospermia
This is a condition where there is a high amount of white blood cells present in the semen. It is more of a semen abnormality than a sperm abnormality.
