Does teratozoospermia have a significant impact on the fetus?

Teratozoospermia has significant impacts on the fetus, specifically manifested in the following aspects: 1. Cognitive effects: An increased rate of sperm abnormalities may indicate a higher risk of pathogenic genes in the fetus, potentially leading to intellectual disability as well as declines in memory, attention, and judgment. 2. Risk of miscarriage and embryonic arrest: Abnormal sperm can reduce the quality of the fertilized egg, increasing the risk of fetal miscarriage and, in severe cases, resulting in embryonic arrest. 3. Fetal malformations: Elevated sperm abnormality rates may directly cause fetal malformations, such as hydrocephalus, congenital heart defects, and spina bifida, among other serious conditions. 4. Other effects: Teratozoospermia may also lead to complications in pregnant women, such as preterm labor and miscarriage, posing threats to fetal survival. The impact of teratozoospermia on the fetus should not be overlooked. It is recommended to undergo thorough pre-pregnancy examinations and implement appropriate monitoring and preventive measures during pregnancy.
