in the horoscope of Revati we see 5th house lord Venus getting debilitated in the 9th house or the bhagyastana which is not good. Ketu is conjoined with Jupiter forming the guru chandal dosha. We Also see that Rahu is placed in the 5th house of Praveen horscope. When Rahu is placed in the 5th house, it will bring delays, obstacles and having children. You will need some medical help so it is best to show to your doctor. It is not a good chart on the progeny front and delays will be there. Doing the Santan Gopal Mantra will help.
