Teratozoospermia is an abnormality affecting male semen in which most sperm are abnormally shaped.
Because of their poor morphology, sperm cannot fertilize the egg and cause sterility.
The causes of teratozoospermia are:
- Genetic alterations
- Chemotherapy and radiation therapy
- Seminal infections and orchitis
- Testicular trauma
- Diabetes Mellitus and meningitis
- Tobacco, alcohol, drugs
- Bad eating habits, toxic, tight clothing...
There are some causes that can be solved (fever, quitting tobacco, healthy habits...) so that the problem in some cases would be reversible.
