Can a man with teratozoospermia conceive naturally?

Many men commonly smoke, and those who smoke frequently face a higher risk of sperm abnormalities, which may contribute to infertility.

Can natural conception occur with teratozoospermia?

From the perspective of eugenics and healthy reproduction, pregnancy is not advisable when sperm morphology abnormalities are excessive; corrective measures should be undertaken prior to conception. Abnormalities such as oversized sperm heads—or other atypical shapes—hinder penetration through the microscopic channels formed by cervical mucus. Sperm with abnormally small heads are often observed in cervical mucus, primarily due to the absence of an acrosome. When the proportion of morphologically abnormal sperm exceeds the normal reference range, active medical intervention is warranted. Forced conception carries risks: miscarriage represents a relatively mild adverse outcome, whereas more severe consequences may include subtle, undetectable neurodevelopmental or cognitive impairments in the offspring.

In daily diet, consumption of animal offal (e.g., liver, kidney) may be increased. Offal is rich in cholesterol—a key precursor for sex hormone synthesis—and also contains adrenal hormones and sex hormones that promote spermatogonial cell division and maturation. Therefore, moderate intake of animal offal can help elevate endogenous testosterone levels, increase semen volume, and improve sexual function.

Low fructose concentration in semen is associated with necrozoospermia (a high proportion of non-viable sperm). Fructose is abundant in honey and many fruits—including pears, apples, grapes, and sweet oranges.
