Really sad to hear the death news of Mr. Prahlad Jani. Before his death, unfortunately researchers failed to identify how he live without eating food and water.
But still we have an opportunity to continue research. Yes ! we should freeze his sperm as soon as possible. If we freeze his sperm means we give birth to a baby
through traditional surrogacy method. The baby who born from his sperm may also have power to live without eating food. So researchers can continue
research (how that baby living witout eating and water) on that baby. Human sperm can survive only for few hours after the death of human. So far more than 24 hours over.
Still I hope Prahlad's sperm remain surviving inside his epididymis by the luck. So I strongly recommend Indian government researchers try to freeze his sperm.
