Conceive or not

Patient: Hi , I couldnt able to ejaculate during sex. So with my erected penis , i had sex first and then i mastrubated & the moment semen came , i inserted to my wife’s vagina. And stayed inside her vagina for around 4-5 mins. Will this help her to conceive without ejaculation but with mastrubating inside vagina!?

Symptoms: Took Tazzle for erection. If i dont take tazzle , erection is just 1-2 mins only.
