Does insemination with frozen sperm increase the likelihood of having a child with birth defects?
All available data indicates that frozen semen does not increase the risk of birth defects. Since the first successful attempt at artificial insemination in humans in 1953, more than 250,000 children have been born from artificial insemination with no increase in birth defects. In fact, the freezing process tends to kill off weaker sperm, and may thus lead to fewer birth defects.
