Patient: Description of condition (onset, main symptoms, hospital visited, etc.): 20 years old, male, mild geodystrophy. He was diagnosed at the age of 4, and his face is still green. I would like to know what to pay attention to when having a child with mild thalassemia. Does it affect the fertility of a woman with common anemia such as iron deficiency anemia? Also, what should I pay attention to when I have sex with a patient with mild thalassemia? Yang Hongchong, Hematology Specialist, The First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine: When choosing a spouse for an unmarried patient with thalassemia minor, it is best to choose a thalassemia-free partner. Married people should find out whether their spouse also has thalassemia or carries the thalassemia gene, and prepare for an amniotic fluid examination in the fifth to sixth month of pregnancy to find out whether the fetus has thalassemia for eugenic selection. Sexual activity should be measured. Maternal health has a major impact on the fetus, so female anemia, even the most common iron deficiency anemia, may have a negative impact on fertility.
