Patient's question:
My cousin and his wife have been married for over two years and have been trying to have a baby. However, they haven't been successful yet. The other day, they had a thorough check-up at the hospital and were told that the infertility was caused by abnormal sperm from my cousin. I asked my cousin to help me ask the doctor what exactly is the reason for the abnormal sperm.Doctor's answer:
The causes of abnormal spermia include urinary and genital tract infections, orchitis caused by the second-order neurons of mumps, epididymal tuberculosis, varicocele, etc. They can all lead to an increase in abnormal sperm, typically including double-headed sperm, which affects sperm quality. The use of hormones or certain chemical drugs, such as anticancer drugs, reserpine, busulfan, and furans, can cause sperm to develop immaturely. Radiation exposure to the gonads can lead to dramatic changes in sperm. Long-term high fever in the scrotum and chronic alcoholism (especially high-concentration spirits) can both cause sperm to become deformed.
