What Causes Male Infertility?

In daily life, some men are unable to father children due to certain underlying causes—yet the specific reasons remain unknown to them. This not only severely disrupts their daily lives but also imposes significant psychological stress. So, what causes male infertility?

What Causes Male Infertility?

Male infertility refers to cases in which a couple has lived together for over one year, engaged in regular unprotected intercourse, yet the female partner fails to conceive—due specifically to factors originating from the male partner. The most common causes are congenital abnormalities, such as abnormal testicular development or absence of the vas deferens. Acquired conditions—including testicular torsion, testicular trauma, orchitis, and testicular tumors—may also lead to testicular atrophy. Additionally, inflammatory conditions affecting the genitourinary tract—such as prostatitis and cholecystitis—can contribute to male infertility.

Varicocele and hydrocele of the testis are also recognized causes of male infertility. Furthermore, congenital chromosomal abnormalities, as well as hyperthyroidism or hypothyroidism, may impair male fertility. Identifying the precise underlying cause enables targeted treatment, thereby improving fertility outcomes.

Patients are advised to maintain emotional calmness and avoid excessive anxiety, which can exacerbate psychological distress. Moreover, individuals experiencing symptoms suggestive of infertility should seek timely medical evaluation and follow evidence-based management strategies under the guidance of a qualified healthcare provider.
