Fertility jabs tied to birth defects


     London: Infertile men, please note — fertility jabs may be harmful for your future child, for a new study says they increase the risk of birth defects in kids.

    The study by University of Adelaide on more than 300,000 babies found that children conceived through the common method of fertility treatment had a significantly higher risk of developing abnormalities than those conceived naturally.

    In fact, babies born as a result of intracytoplasmic sperm injection (ICSI) — where a single sperm is injected directly into egg — were more likely to suffer abnormalities, ‘The Daily Telegraph’ reported.
    In ICSI, the embryologist injects a single sperm directly through the shell of egg and depositing it inside. This means that abnormal sperm, which would normally be filtered out by the process, are able to fertilize the egg.

    However, researchers were unable to establish whether this was because the ICSI technique itself increases the risks of abnormality or because men suffering from extreme sperm damage were more likely to pass on genetic anomalies.

    But the study also found that IVF treatment did not increase risk of birth defects. In IVF treatment, sperm and eggs are mixed together in a dish and sperm breaks into the egg on its own in order for fertilisation to occur.
