Girls should be married when they attain age of fertility, said Samajwadi Party MP ST Hasan on Friday while talking about the Centre's move to raise the minimum age of marriage for women to 21.

Speaking to ANI, Hasan said, " The fertility age of women ranges from 16-17 years to 30 years. Proposals for marriage start coming at the age of 16. If the marriage is delayed, there are two disadvantages: One is the possibility of infertility. The second is that children are not settled when one is ageing. When you are in your last decade or so of life, your children are still students. We are breaking the natural cycle."
