How do you check for Progeny, Child?

Most of the married people want children (except few). They are depressed, if no child born. Here are some of the planetary positions in a horoscope to indicate for them to be childless.

1. The Lord of Lagna (Ascendant) and Mercury occupy the 4 or 7th or 10th house.
2. Mars is placed in the Lagna , Saturn in the 8th house and the Sun in the 5th house;
3. When the 5th or 8th or 12th houses ( any one of them) occupied by malefic;
4. If Venus occupies the 7th house, The Moon in the 10th house and the malefic planets occupy the fourth house.
5. If the malefic in aspect by benefics , occupy the 8th house from the Moon.
6. If the 7th house occupied by Venus and Mercury, 4th house by Malefic and Jupiter in the 5th house.
7. The Moon occupies the fifth house and malefic occupy the Lagna , the Seventh, and the 12th house (he will neither have wife nor children) - in all the given places.While at this, some of you had asked me to give the planetary positions -combinations - preventing birth of male child , which I add below:
8. Rahu in the 5th house, either in the sign owned by Mars ( Aries or Scorpio) or in aspect by Mars (Rahu in 4th, 7th and 8th house from the position of Mars).
9. Saturn in the 5th house from Lagna and in aspect from the Moon (7th house from Moon) and the lord of 5th house is associated with Rahu ( for example: Let us assume Cancer - Karkataka as Lagna; Saturn is in Scorpio - Vruchika - 5th house to Lagna,, AND The Moon is in Taurus - Rishab - where, the Moon is exalted - and the lord of Scorpio - Mars, is with Rahu in any house in the Horoscope - this result is seen)
10. Jupiter in combination with Rahu or Ketu, Lord of 5th house is weak and or powerless, and the lord of Lagna is combined with Mars ( Example : Let us assume Scorpio- Vruchika, is the Lagna - Lord of 5th house , Pieces - Meena, Jupiter is in Mithuna with Rahu/Kethu- Gemini, the 8th house (weak house to Scorpio) from Scorpio, and is combined with Mars the lord of Lagna - Scorpio - is positioned with Jupiter in Mithuna, this result is seen)
11. Jupiter in association with Mars, Rahu occupies the Lagna and the lord of 5th is placed in th sixth or 8th or 12th house .
12 Lords of Lagna and fifth house, are powerless/weak, and all malefic planets occupy the 5th house, with Jupiter and Mercury.
13. The Lord of Lagna is associated with Rahu and the Lord of 5th house is combined with Mars, and ‘Puthrakaraka’ Jupiter is in aspect from Rahu/Kethu.There are many more combinations which could indicate preventing birth of male child.
