In the female chart, the 5th house is semi barren occupied by a retro 6th and 7th lord Saturn. The 5th lord Jupiter is in the 9th in the rasi chart aspecting both the lagna and the 5th house. However, it moves to the 8th bhava in the bhava chart.
In the Saptamsa chart, Jupiter, the karaka for children, aspects both the Lagna lord and the 5th lord. The 5th house is in a barren sign. Ketu occupies the lagna indicating a probable abortion of the first conception.
Jupiter is in the nakshatra of Venus which is the dasa lord and hence is activated now. The 8th house indicating the garbasthana has no malefic associations.
Overall, this chart has potential for child birth but may need medical help.
In the male chart, the 5th lord Jupiter occupies its own house along with an exalted Venus and a closely conjunct Rahu. This conjunction leads to Sarpa dosha and a sarpa samskara puja is needed to be performed. In Saptamsha, Karaka Jupiter (in his debilitation house) aspects the Lagna lord and Venus the 5th lord is in the house of Jupiter. Jupiter dasa starts from mid April 2025.
If the suggested puja has been performed by then, there are good chances for child birth next year.
Please note that the puja is not to be performed by you if your father is alive. In that case, he has to do on your behalf with proper sankalpa.
Regarding relationships, you have Mars in the 7th rasi and 7th Bhava. Your wife also has Mars with Rahu in the 7th Rasi but in the 6th bhava. Your Mars is active because your antardasa lord is Mars. Her Rahu is active because the dasa lord Venus is in the nakshatra of Rahu. Further Mars in the 7th is not considered good since it is the marana karaka sthana for Mars. And both of you have strong Sun. Hence all the fights. You can pray to Lord Subramanya daily and ask your wife to recite a Devi (Durga) Stotra daily.
