Patients often ask why it is necessary to check the preoperative tests of the male partner (Hepatitis B, Hepatitis C, AIDS, Syphilis), Mycoplasma, Chlamydia, Gonococcus, since the sperm used in donor insemination and IVF come from sperm banks, not the male partner? It is because if the male partner suffers from the above infections, the disease may be infected through the couple’s sexual life, close contact, etc. Early examination and early detection will help to take appropriate measures to avoid infection to the female partner, especially after the success of the assisted conception and may be passed on to the fetus.
