Song Yuhong was born with spina bifida, a congenital condition that left her in a wheelchair. But that has not stopped the 41-year-old from realizing her dream of becoming a mother.

"The most frequent question I'm asked is, How can you still have sex and have babies if you are paralyzed?" said Song, who has two girls, aged 3 and 1.

"There's still so little understanding. Yes, of course we can. We need it, just as you do!"
