This Post 2 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]
NO2 is an odd electron molecule ,i.e. the central nitrogen atom has a single unpaired electron which makes it unstable.
so it dimerises to gain stability

It is controlled by oxytocin as it level when increased causes labour pains
howevwer relaxin also plays an important role as it softens the ligaments of pubic symphysis and makes parturition easier
relaxin is also a indicator of pregnancy as during onset of pregnancy it softens the ligaments of feet which makes the female feel as if her shoes' size has increased.
