Well it snot always that Bollywood makes a socially relevant movie. Its rather very rare that Bollywood comes up with such a movie which can be good for the cause of the society.
CBFC however makes sure that all such films face a lot of problem or do not release at all.
Phullu which is a movie based on menstruation is facing the same from the CBFC, it has been awarded an A certificate. The reason that it is understood to be a taboo subject in India and its a stigma sort of thing in the Indian society as per the perception of the CBFC..
Makers of Phullu are however not happy with their film being awarded an A certificate and taking the matter to the public. Phullu is a movie which has been directed by Abhishek Saxena and speaks strongly about the subject of menstruation.
Many are asking CBFC as what is so ADULT about periods.
