Manava Dharmashastra 5.159

5.159

putro me jāyatāmityabhilāṣaḥ | so'patyalobhastato hetoryā bhartāramatikramya vartate'nyena samprayujyeta | sā iha loke nindāṃ garhāṃ prāpnoti, svargaṃ na prāpnoti |

Medhātithi’s commentary (manubhāṣya):
Her longing being—‘may a child be born to me’; this is the ‘longing for a child.’ From this cause if the woman disregards her husband and becomes wedded to smother man, she brings to herself ‘disgrace’—bad name—‘in this world’; and never reaches heaven.—(159).
