Just as the rasis and grahas (planets), the nakshatras also have been classified into different groups on the basis of their characteristics and attributes.

This would be helpful in predicting the sex of the progeny, by detemiining in which star constellation, the lord of the 5th house is situated and in which rasi and the planet (Ududasa lord) ruling that star (nakshatra).
