(b) This Yoga applies only in the absence of the Yoga mentioned already.

13. If (at the time of conception), the Moon and the Sun, occupying respectively any of the even and odd signs, aspect each other, or (2), if Saturn and Mercury (occupying, respectively any of the even and odd signs) aspect each other, or (3) if Mars (in an odd sign) aspect (or be aspected by) the .Sun in an even sign, or (4) if the Moon and Lagna in odd signs be aspected by Mars (in an even sign), or (5) if Mars aspect the Moon and Mercury occupying respectively even and odd signs, or (6) if Venus, Lagna and the Moon occupy (male signs and) male Navamsas, the issue will be a hermaphrodite.
These Napumsaka Yogas take effect only in the absence of male and female Yogas.
14. If, when the Moon and Venus are in even signs Mercury, Mars, Jupiter and Lagna be in odd signs, or if a male planet aspect Lagna and the Moon in the even signs, or if Mercury, Mars, Jupiter and Lagna be powerful and occupy even signs, the issue will be a male and a female child. Again, if Lagna and all the planets occupy the Ubhaya (common) Navamsas and be aspected by Mercury in his Navamsa, the issue will be three children: Of these, two will be male children if the Navamsa occupied by Mercury be that of Gemini, and two will be female children if such Navamsabe that of Virgo. Again, if, when Mercury occupies the Navamsa of Gemini, the other planets and Lagna occupy the Navamsas of Gemini and Sagittari, all the three will be male children; and if, when Mercury occupies the Navamsa of Virgo, the other planets and Lagna occupy the Navamsas of Virgo and Pisces, all the three will be female children.
15. If the last Navamsa of sign Sagittari begin to rise, if all the planets occupy the Navamsa of Sagittari and be powerful, and if the rising sign be aspected by powerful Mercury and Saturn, the issue will be more than three children (a).

16. In the first mouth of pregnancy, the embryo is formed; in the second, it becomes flesh; in the third, the limbs are formed; in the fourth, the bones are formed; in the fifth, the skin is formed; in the sixth, the hair begins to grow; in the seventh, intelligence is infused into the child (a).
The lords of the several months from the first to the seventh are Venus, Mars, Jupiter, the Sun, the Moon, Saturn and Mercury respectively.
(a) In the eighth month, the child begins to eat through the navel cord. In the ninth month, the child is filled with cares, and in the tenth month the child is born. The lord of the 8th month is the lord of the rising sign at the time of conception. The lord of the 9th month is the Moon, and the lord of the 10th month is the Sun. According to Yavaneswara, the lord of the first month is Mars and that of the second month is Venus.
There will be miscarriage of pregnancy in that month whose lord happens to be afflicted at the time of conception; but if any of the planets be of dim appearance, the fetus will simply suffer in the month of the particular planets. If the Sun be powerful the child would resemble its father, and if the Moon be powerful, the child would resemble its mother. The health and disposition of the child follow those of its parents at the time of conception.
17. If Mercury occupy the fifth or the ninth house (a) from the rising sign, and if at the same time the other planets be powerless, the face, the legs, and the hands of the child will be doubled. If the Moon occupy sign Taurus and if malefic planets occupy the Riksha Sandhis (b) the issue will be a mute child; but if the Moon be aspected by a benefic planet, there will be speech after a long time (c).
