Sperm quality is the key factor to male ferterlity ability. However, unhealthy life style and other factors will also affect sperm quality. Sperm quality can be affected by many factors, including lifestyle, environmental factors, physical health and genetics. The following are the main factors that may cause sperm quality to decline:
Unhealthy life style
Unhealthy life style like smoking, over drinking, bad eating habits, lack of exercise, overwork and staying up late will affect sperm quality.
For example, smoking will produces a large number of free radicals, which can damage sperm DNA and reduce sperm count, motility and morphology. And over drinking will affect testosterone secretion, inhibit sperm production, and lead to a decline in sperm quality. Lack of sleeping for long time will causes hormone disorders and reduces sperm production ability.
Environmental factors
Environmental factors like high temperature environment, environment pollution, radiation and electronic devices will affect the sperm quality. For example, excessively high testicular temperature can inhibit sperm production, such as long-term hot baths, saunas, wearing tight pants or long-term sitting work. And get in touch with air pollution and heavy metal will affect sperm quality. Long time of exposure to radiation sources, frequent use of electronic devices may also affect the testicular function.
Age factors
As men age (especially after 40 years old), sperm quality will gradually decline, the risk of DNA damage will increase, and sperm motility and quantity will decrease.
Psychological factors
Long term mental stress and anxiety can cause hormone imbalances. Mental health issues is highly relative with sperm quality decrease, it may affect life style and hormone secretion.
Medicines and drugs
Taking some kinds of medicine for a long time (such as chemotherapy drugs, antidepressants, antihypertensive drugs) may inhibit sperm production. Drugs like marijuana, cocaine, and heroin can cause a decrease in sperm count, decreased motility, and abnormal morphology.
Genetic factors
Genetic factors like chromosomal abnormalities and gene mutations will affect the production of sperms.
In conclusion, sperm quality decreasing is relative with many factors, including life style, environmental affection, disease, mental condition and other factors. In order to improve sperm quality, male should take effective measures like improving life style, keeping healthy diet, avoiding harmful substances and have a health check regularly. If sperm quality decrease gradually, it is recommended to consult a professional doctor in time for comprehensive evaluation and treatment.
