The (child-yielding) Yogas mentioned will be futile for the couple without virility, just as the blind are devoid of many qualities (i.e. advantages).

Notes: The Sloka is suggestive of the fact, that irrespective of promising combinations of Grahas at the time of intercourse, one should have good PutrBhava/Putrslord. Unless the promise for progeny is from the natal horoscope, such indications from Adhana are of no effect.

During the first month of conception, the embryo will only be in the form of ogulated blood and (the development) is ruled by Sukr. Mangal presides over the second month, while it takes the form of a seed (like Pingaka, or Pingaksha seed). In the third month it transforms into a sprout and is ruled by Guru; marrow and bones are added in the 4^th month ruled by Surya; development of skin, fat and blood takes place in the fifth month under the rulership of Candr; Sani takes over the process of growth of limbs in the sixth month; senses occur to the child under the rulership of Budh in the seventh month hunger and thirst are felt in the 8^th month, which process is controlled by Lagns lord of Nisheka (i.e. the Grah ruling the moment of intercourse, that led to conception) and Candr rules the ninth month, when the child develops excitement and moves in the womb of the mother. The 10^th month is ruled by Surya preceding the delivery.
