Can I be a dad

[Confusiusdoesntsay]

Hi, wasn't sure where to go with this, so I'll try here 1st.
I'm a married man (25 yrs), only child,young mid 50s, engineer, no children, financially stable, all parts included, in good working order!
My wife due to cancer had a hysterectomy at a very early age.
A child has never really crossed my mind......until now.
Leaving my wife isn't an option, I'm too old for sperm donation, besides, I would like some input at least in my child's upbringing. I would want them to know who their father is.
I don't know of places that could deal with this, or if any women would even accept the situation.
So, I would be interested in your views, and if anyone could point me in the right direction.
Thank you in advance.

would have to have some sort of bond with the mother,

What sort of bond?

May I also add, I am quite conservative in family structures. So I realise that any scenario that may arise, can never be ideal.
However, I feel I can still offer a better situation that a lot of children unfortunately find themselves in.

A lesbian couple would be putting themselves at higher risk of having a disabled child because of your age Vs using younger males sperm. I have no idea why anyone would make that choice?

No no no no no. Children deserve to be brought in to a loving environment with a biological mother and father there to protect and nurture them. You had your chance and you missed it. Accept it and move on.
