Question
My wife and I have been unable to conceive naturally for a long time. After examination, both our reproductive systems and endocrine functions are normal, but only sperm morphology abnormalities were found. Since there is a case of XYY chromosome in the family, I would like to know how to check if I also have this issue.
Answer
Hello, your cousin has an XYY chromosome, which does not necessarily mean you have a chromosomal abnormality as well. You can undergo a blood test to confirm your chromosomal status. Currently, your sperm morphology abnormalities may be due to varicocele-induced temperature rise. It is recommended that you have a blood test, with 3 milliliters of blood taken for a chromosome examination.
