Let us assess your wife's horoscope first,
at first glance ther affliction is not forthcomming but a harder look reveals the problem. The 5th lord is Ravi. all things being equal people with a Mesha Ascendent have fewer Children. this 5th lord Ravi is in the 12th house which is a Dusthana. but what has really affected him is that he is in Revathi Nakshatra owned by Budha. Budha is combust and is Debilitated in the chart. he is a utter malefic for this lagna owning the 3/6th house. The 5th house is caught between 2 Malefics Shani and Rahu. this affliction is carried over to the Chandra lagna too.From chandra Lagna the 5th lord Budha is again debilitated.
In the D7 chart the lagna has shifted just 1.34 secs back. I will take the lagna to be Pisces. The lagna, chandra lagna, and the 5th house is aspected by the 12th lord Shani.
for anything to be experienced in life the lagna should be strong. Kuja the lagna lord has landed in a enemy and a weak Rashi. Guru, the 12th lord and Santhana karaka and Ketu's presence in the lagna is not to be taken lightly.
Through hard work and spiritual practices, a person gets honor and dignity. The lazy one who puts in no efforts is like a fool who allows salt to be spilled on the wounds of his misfortunes. The idler depending only on fate, achieves nothing. - K.N.Rao ji
