When the Father and Mother beget one through mutual desire,—this that he is born in the womb is to be regarded as his “production.”—(147)

Medhātithi’s commentary (manubhāṣya):
These two verses are purely valedictory.

‘When the Father and. Mother beget him’—the child—‘through mutual desire’—in secret, under the influence of desire.

‘Should be regarded as his production;’—that the child is born in the womb of the Mother—i.e., b ecomes endowed with his several limbs—this is mere production. And those entities that have their production are sure to be destroyed; so that what is the use of that ‘production’ which is doomed to immediate destruction?—(117)

This verse is quoted in Vīramitrodaya (Saṃskāra, p. 480).
