Brihat Parashara Hora Shastra
केन्द्रत्रिकोणसंस्थे वा पूर्णं पुत्रसुखं वदेत् । षष्ठाष्टमव्ययस्थे तु सुताधीशे त्वपुत्रता ॥ २॥
Should Putr‟s Lord be in Ari, Randhr, or Vyaya Bhava, there will be no offspring. Should the Lord of Putr be combust, or be with malefics and be weak, there will be no children; even, if per chance issues are obtained, they will only quit the world soon.
