Bro to keep it simple... according to Sarala she thinks her student doesn't know about female reproductive system works..that's all..so obviously Vishnu would not think as he is not from science background... Further per my knowledge .. further females are capable of storing spermatozoa in their reproductive tracts until the eggs are ready to be fertilized.. anyways let's move on with story... To be Frank i myself didn't know that girl's can't produce sperms hahahha...so poor guy... Vishnu would not aware lol

Really? That's too childish of you bro hahahah.
