I am planning to have a kid and since I am having a problem ejaculating during intercourse, I masturbate and ejaculate into a cup and take this semen in a syringe without the needle and inject it in my wife's vagina. I am doing this for the past 3 months but my wife did not conceive. I have the following doubts regarding this procedure. Can a person conceive in this method wherein the semen is injected into the vagina in a syringe rather than depositing the semen into the vagina via natural intercourse? If yes then would it be possible to answer the below questions, 1. When I take the semen in the syringe many air bubbles get inside the syringe. Is it fine to inject the semen with these air bubbles. If not is there a way to remove these air bubbles? 2. Can I use any type of syringe for this or is it necessary to use a particular kind of syringe? 3. I use a sample container made of plastic to collect my semen during masturbation. Is it safe for the sperm/semen to be collected in a sample container made of plastic?
