As per KP method of analysis : Retrogression has no effect in case of natal charts. It has an impact in horary charts only. Saturn is in 9th house and also 9 sign. 9th house is a common sign. So it gives the disease to be lingering type. Saturn gives 6th house and 12th house results through 9th house(its own house). So Saturn gives success in your day to day service and relinquishment of job. It has no effect on your marriage house (7th house), as Venus and Jupiter are there.
The nature of the spouse depends on 7th cusp sub lord. It is Mercury (in 6th house – open enmity, disputes, desirous of separation, litigation). Mercury is the lord of 12th house (separation, bed comforts, secret enmity etc). Mercury gives 8th house (sudden events, disappointments) through his star lord Ketu and 2nd house (finance) and 7th house (self to the boy) through sub lord. It means he always desires your money or dowry, your property. He will deal with jovial words.
Being placed in 7th house, Venus and Jupiter gives handsome and robust look. Seems to have a pleasant and jovial nature. This is the apparent look.
Mars is in 6th house being in less degrees to 7th cusp. It gives foreign trips to him.
Note: Sign is not important. It helps us to know the strength of the planets. House is important as it gives the matters like marriage – 7th house.
Good Luck
