 SB 4.27.7

duhitrr dasottara-satam
 paurañjanyah praja-pate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
O Prajapati, King Pracinabarhisat, in this way King Purañjana also begot 110 daughters. All of these were equally glorified like the father and mother. Their behavior was gentle, and they possessed magnanimity and other good qualities.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Children begotten under the rules and regulations of the scriptures generally become as good as the father and mother, but children born illegitimately mainly become varna-sankara. The varna-sankara population is irresponsible to the family, community and even to themselves. Formerly the varna-sankara population was checked by the observation of the reformatory method called garbhadhana-samskara, a child-begetting religious ceremony. In this verse we find that although King Purañjana had begotten so many children, they were not varna-sankara. All of them were good, well-behaved children, and they had good qualities like their father and mother.
Even though we may produce many good children, our desire for sex that is beyond the prescribed method is to be considered sinful. Too much enjoyment of any of the senses (not only sex) results in sinful activities. Therefore one has to become a svami or gosvami at the end of his life. One may beget children up to the age of fifty, but after fifty one must stop begetting children and should accept the vanaprastha order. In this way he must leave home and then become a sannyasi. A sannyasi’s title is svami or gosvami, which means that he completely refrains from sense enjoyment. One should not accept the sannyasa order whimsically; he must be fully confident that he can restrain his desires for sense gratification. King Purañjana’s family life was, of course, very happy. As mentioned in these verses, he begot 1,100 sons and 110 daughters. Everyone desires to have more sons than daughters, and since the number of daughters was less than the number of sons, it appears that King Purañjana’s family life was very comfortable and pleasing.
