What Causes Abnormal Semen in Men?

Abnormal semen in men can impair male fertility and also impose a psychological burden on affected individuals. Such abnormalities are primarily attributable to unhealthy lifestyle factors. What, then, are the underlying causes of abnormal semen in men?

What Causes Abnormal Semen in Men?

The primary factor influencing semen quality is the frequency of sexual activity. Excessively frequent intercourse may result in thin, low-volume semen. Conversely, prolonged abstinence may cause semen to appear yellowish and slightly thicker. With moderate sexual activity, semen typically appears white and has a characteristic fishy odor. The key is maintaining a balanced lifestyle—ideally engaging in intercourse approximately every three days.

Abnormal semen may also stem from various urological or reproductive disorders, including seminal vesiculitis, orchitis, asthenospermia (reduced sperm motility), prostatitis, incomplete semen liquefaction, teratospermia (abnormal sperm morphology), and other structural or functional sperm abnormalities. Therefore, upon noticing any semen abnormalities, men should promptly seek medical evaluation and undergo appropriate diagnostic testing; treatment should then be tailored based on the specific findings.

In daily life, men should also eliminate detrimental habits such as chronic sleep deprivation, prolonged sitting, extended computer use, long-term smoking, and excessive alcohol consumption. Dietarily, spicy and irritating foods should be minimized, while foods rich in zinc and vitamin C—known to support improved sperm quality—should be consumed more frequently.
